Orthostatic Hypotension: A Patient's Guide to Why You Get Dizzy on Standing and What to Do About It

A 78-year-old woman comes into clinic after a fall in her kitchen. She got out of a chair to refill her coffee, took two steps, and the lights went out. She woke up on the floor with a bruise on her cheek. Her daughter brought her in, worried. When we check her blood pressure lying down, it’s 140 over 80. After three minutes of standing, it’s 100 over 60. Her medication list includes a blood pressure pill, a water pill, an alpha-blocker for nighttime urinary symptoms, and a low-dose antidepressant. We have a diagnosis, a likely cause, and a treatment plan in one visit.

That’s the typical orthostatic hypotension story in older adults. The dizziness on standing is usually a side effect of the medications that were prescribed for other reasons. Catching it matters because the falls it produces are real and serious. A broken hip in an 80-year-old is the kind of event that changes the rest of a person’s life.

This guide walks through what orthostatic hypotension is, who gets it, how the diagnosis is made, what causes it, and how it’s treated. The emphasis is on what you can do at home and what to expect from your team. I want you to walk away understanding why standing makes you dizzy and what the menu of fixes looks like.

What Is Orthostatic Hypotension, in Plain English?

Orthostatic hypotension is a drop in blood pressure when you stand up. The body normally has a fast reflex that keeps blood pressure steady on standing, by tightening blood vessels in the legs and speeding up the heart. When that reflex fails or is overpowered, blood pressure falls, blood flow to the brain drops, and you feel lightheaded, dizzy, sometimes faint. The formal definition is a fall of at least 20 mmHg systolic or 10 mmHg diastolic within 3 minutes of standing.

What “Orthostatic” and “Hypotension” Mean

“Orthostatic” means related to standing upright. “Hypotension” means low blood pressure. Put together: low blood pressure when standing up. The condition is a sign rather than a disease in itself. Something has thrown off the normal control system that keeps blood pressure steady when you change position.

How Blood Pressure Normally Adjusts When You Stand

When you go from lying or sitting to standing, gravity pulls roughly half a liter of blood down into your legs and the blood vessels of your abdomen. Without compensation, blood pressure in your brain would crash within seconds and everyone would faint every time they stood up. The body has a fast reflex system that prevents this. Pressure sensors in the carotid arteries (the big arteries in your neck) and the aorta (the big artery coming out of your heart) sense the falling pressure and immediately signal the brain stem. The brain stem fires the sympathetic nervous system: blood vessels in the legs tighten, the heart speeds up by 10 to 20 beats per minute, and blood pressure stabilizes within 30 to 60 seconds. Most healthy people feel a brief flicker of lightheadedness, then nothing.

What Goes Wrong in Orthostatic Hypotension

Three broad things can break this reflex. The autonomic nervous system itself can be damaged (by Parkinson’s disease, diabetes-related nerve damage, multiple system atrophy, or pure autonomic failure). Medications can block the normal compensatory responses (blood pressure pills, alpha-blockers, diuretics, certain antidepressants). Or the body can have too little blood volume to maintain pressure (dehydration, blood loss, prolonged bed rest). The result is the same: blood pressure falls on standing, and you feel it.

Why It Matters

The dizziness on standing is more than unpleasant. It causes falls, and falls cause injuries that can be serious or life-altering in older adults. Repeated episodes also reduce blood flow to the brain and heart over time, which is linked to higher long-term rates of stroke, heart attack, cognitive decline, and death. The condition is worth catching and treating.

What Are the Symptoms?

The hallmark is dizziness or lightheadedness within seconds of standing up. Other common symptoms include blurred or graying vision, weakness in the legs, a “coat hanger” ache across the shoulders and neck, brain fog, nausea, and in worse cases near-fainting or actual fainting. Symptoms often improve when you sit or lie back down.

Dizziness and Lightheadedness

The most common symptom. Most patients describe it as “feeling woozy” or “the room spinning” within seconds of standing. The sensation usually settles within a minute or two if the body manages to compensate, or sooner if you sit down. Some patients have learned to lean against a wall or a counter when they stand, instinctively buying time.

Vision Changes

Reduced blood flow to the brain shows up in the visual system early. Many patients describe their vision “graying out” at the edges before clearing, or seeing spots or stars. Some experience brief blurred vision. A few have transient loss of vision in one or both eyes.

Weakness and Trouble Walking

The legs can feel rubbery on standing, especially in the first few steps. Some patients describe needing to grip the handrail when going down stairs because their legs won’t reliably hold them. It comes from reduced blood flow during the first 30 to 60 seconds of being upright, not from leg weakness as such.

Coat Hanger Ache

A characteristic pattern of pain across the shoulders and the back of the neck, in the shape of a coat hanger. It comes from reduced blood flow to the muscles of the neck and upper back when blood pressure drops. It often improves when you lie down, which is unusual for muscle pain and is a clue to the diagnosis.

Brain Fog and Cognitive Symptoms

Some patients describe a fog or fuzziness in their thinking when they’re upright that clears when they sit. They may have trouble concentrating, finding words, or following conversations. Cognitive symptoms are often the most disabling part of the condition for working-age patients.

Nausea

Reduced blood flow to the gut can cause nausea on standing, sometimes with vomiting in severe cases.

Fainting

Actual loss of consciousness happens when the blood pressure drop is severe enough to drop brain perfusion below the threshold of consciousness. Fainting from orthostatic hypotension typically happens within a minute or two of standing, often without much warning beyond the usual dizziness.

Symptoms That Improve When You Lie Down

Almost all orthostatic symptoms get better when you sit or lie back down. This pattern is the diagnostic clue. Symptoms that don’t improve with lying down point to something else.

When Symptoms Happen

Classic orthostatic hypotension produces symptoms within 3 minutes of standing. Initial orthostatic hypotension produces symptoms in the first 15 seconds (often missed by standard testing). Delayed orthostatic hypotension produces symptoms 5 to 30 minutes after standing, often during prolonged standing tasks like grocery shopping, cooking, or attending church. The pattern matters for both diagnosis and management.

Who Gets Orthostatic Hypotension?

Older adults are at highest risk. About 20 percent of people over 65 have it. People taking multiple blood pressure medications, alpha-blockers, diuretics, or antidepressants are at high risk regardless of age. People with Parkinson’s disease, diabetes-related nerve damage, multiple system atrophy, or pure autonomic failure are at elevated risk. Dehydration, prolonged bed rest, and recent blood loss are common precipitants.

Age-Related Risk

The reflex that keeps blood pressure steady on standing gets weaker with age. The pressure sensors become less sensitive, the blood vessels become stiffer, and the heart’s ability to respond to stress declines. By age 65, about 20 percent of adults have measurable orthostatic hypotension. By age 80, it’s closer to 30 percent.

Medications That Commonly Cause It

This is the most important category because the cause is often fixable by changing the medication. The drugs most commonly responsible:

Blood pressure pills, especially when used in combinations or at high doses. Alpha-blockers, prescribed for high blood pressure or for prostate symptoms (terazosin, doxazosin, prazosin, tamsulosin). Diuretics (furosemide, hydrochlorothiazide, torsemide), which reduce blood volume. Tricyclic antidepressants (amitriptyline, nortriptyline). Some newer antidepressants. Antipsychotics (especially older ones like haloperidol and some newer atypicals). Parkinson’s medications (levodopa, dopamine agonists like pramipexole and ropinirole). Nitrates for chest pain. Sildenafil and tadalafil for erectile dysfunction. Opioid pain medications.

A medication review with your team is the first step in evaluating orthostatic hypotension, almost without exception.

Parkinson’s Disease

About 30 to 50 percent of people with Parkinson’s develop orthostatic hypotension at some point, often early in the disease before the motor symptoms are prominent. It’s part of the disease’s autonomic involvement, not just a medication side effect, though the Parkinson’s medications themselves can worsen it.

Multiple System Atrophy

A rare neurodegenerative condition that affects the autonomic nervous system early and severely. Patients often have profound orthostatic hypotension as one of the first signs, sometimes before any motor symptoms appear.

Pure Autonomic Failure

A primary autonomic disorder where the autonomic neurons degenerate without the motor or cognitive symptoms of Parkinson’s or multiple system atrophy. Pure autonomic failure tends to progress slowly and is the most “orthostatic-dominant” of the autonomic conditions.

Diabetic Autonomic Neuropathy

Long-standing diabetes (especially type 1 or poorly controlled type 2) damages the small nerve fibers that control autonomic function. The damage can affect heart rate, blood pressure, digestion, and bladder function. Orthostatic hypotension is one common manifestation.

Volume Depletion

Dehydration (poor fluid intake, vomiting, diarrhea, diuretic overuse), blood loss (recent surgery, gastrointestinal bleeding), or prolonged bed rest can all reduce blood volume enough to produce orthostatic symptoms. Volume-depletion orthostatic hypotension typically resolves once the underlying cause is addressed.

Adrenal Insufficiency

The adrenal glands produce hormones that help maintain blood pressure. Adrenal insufficiency (Addison’s disease, adrenal suppression from chronic steroid use) can cause orthostatic hypotension as one of its presentations.

Other Causes

Spinal cord injuries (especially at higher cord levels), amyloidosis, alcoholism, vitamin B12 deficiency, paraneoplastic syndromes, and certain genetic conditions can all produce orthostatic hypotension. These are less common but worth screening for in patients with no obvious medication or age-related cause.

How Is It Diagnosed?

The basic test is simple: lie down for 5 minutes, then have blood pressure and heart rate measured. Stand up. Repeat at 1 minute and 3 minutes. A drop of at least 20 mmHg systolic or 10 mmHg diastolic confirms the diagnosis. The heart rate response gives a clue about whether the autonomic system is involved. A tilt table test or extended monitoring is added when the basic test doesn’t capture what your symptoms suggest.

Bedside Orthostatic Vital Signs

You lie quietly on the exam table for at least 5 minutes. The team measures your blood pressure and heart rate while you’re lying down. Then you stand up. Your blood pressure and heart rate are measured at 1 minute and at 3 minutes. A drop of 20 mmHg or more in the systolic (top) number or 10 mmHg or more in the diastolic (bottom) number confirms orthostatic hypotension.

What the Heart Rate Response Tells Us

In a healthy person, heart rate rises 10 to 20 beats per minute on standing as the body tries to compensate for the falling blood pressure. In neurogenic orthostatic hypotension (the autonomic system is damaged), the heart rate response is blunted; it may rise less than 10 beats per minute, or not at all. In non-neurogenic causes (medications, dehydration), the heart rate response is usually preserved and may even be exaggerated.

Tilt Table Testing

If the bedside test is normal but symptoms strongly suggest orthostatic hypotension, or if the team wants to distinguish classic from delayed orthostatic hypotension, a tilt table test is the next step. The patient is strapped to a table that tilts upright, and blood pressure and heart rate are monitored continuously for 30 to 45 minutes. The test catches delayed orthostatic hypotension that the bedside test would miss. For more on this test, see our guide to tilt table testing.

Lab Tests

Lab tests look for treatable contributors. A complete blood count looks for anemia. A basic metabolic panel checks kidney function and electrolytes. Thyroid function tests rule out thyroid disease. Vitamin B12 may be checked. In selected patients, morning cortisol screens for adrenal insufficiency.

Plasma Norepinephrine

In specialized centers, blood levels of norepinephrine (the main hormone of the sympathetic system) are measured lying down and standing. In healthy people, the level should rise substantially on standing. A blunted or absent rise points to neurogenic orthostatic hypotension.

Autonomic Testing

In atypical cases, formal autonomic function testing (heart rate variability with deep breathing, Valsalva maneuver response, quantitative sudomotor axon reflex test) is done in a specialty lab to characterize the pattern of autonomic involvement. This is most useful when the team suspects a specific autonomic disorder.

Holter Monitor or Patch

If the symptoms aren’t reliably reproduced in clinic, an ambulatory blood pressure monitor or rhythm monitor can capture episodes at home. Some patients only get symptoms after meals, in the heat, or with specific activities, and home monitoring catches what an office visit can’t.

When the Workup Should Expand

If basic testing doesn’t explain the picture, or if there are other concerning features (severe symptoms, rapid progression, neurological signs, weight loss, family history), the workup expands to look for the underlying autonomic condition. Neurology referral is often appropriate in these cases.

What’s the Best Way to Prepare for an Orthostatic Evaluation?

Bring a complete medication list including over-the-counter drugs, supplements, and herbal preparations. Bring a written log of when symptoms happen, what makes them worse, and what makes them better. Don’t dehydrate before the test; drink normally. Wear loose clothing. Skip caffeine and alcohol for 24 hours. Take your usual medications unless the team tells you otherwise.

A Week Before

Confirm the appointment. Start a symptom log: when you feel dizzy, what you were doing, how long it lasted, what helped. The log is the most useful thing you’ll bring to the visit.

A Day Before

Drink normally. Don’t load up on water (extra fluid can mask the orthostatic drop). Don’t dehydrate. Eat normal meals. Avoid alcohol; alcohol worsens orthostatic hypotension and can confound the test.

The Day Of

Eat a light breakfast. Take your usual medications unless told otherwise. Wear loose clothing and slip-on shoes. Bring your medication list. Plan to arrive a few minutes early to settle before testing.

What to Tell the Team

Be specific about your symptoms. “Lightheaded on standing” is less useful than “I get lightheaded within 10 seconds of standing, I have to grip the counter, and it lasts about 30 seconds.” Mention any falls or near-falls in the last year. List every medication, including ones you take occasionally or as needed. Mention recent surgeries, hospitalizations, or major weight changes. Mention if anyone in your family has Parkinson’s, multiple system atrophy, or pure autonomic failure.

How Is It Treated?

Treatment starts with a careful medication review, since drugs are the most common reversible cause. Lifestyle measures form the foundation: more water, more salt (if your other conditions allow it), counter-pressure maneuvers, compression stockings, slow position changes, sleeping with the head of the bed elevated, and avoiding heat. Medications like midodrine, droxidopa, fludrocortisone, and pyridostigmine are added when lifestyle isn’t enough.

Medication Review (Always the First Step)

The team goes through your medication list and asks which drugs can be stopped, reduced, or substituted. Common targets: extra blood pressure pills, alpha-blockers (especially the older ones, where switching to a more selective agent for prostate symptoms can help), diuretics taken at high doses, tricyclic antidepressants when alternatives exist, and any redundant or marginally indicated medications. This step alone resolves many cases.

Fluid Intake

Aim for 2 to 3 liters of water per day unless you have a condition (heart failure, kidney disease) that limits fluid intake. Spread it across the day rather than drinking it all at once. Drink a large glass of water (about 16 ounces) before you get out of bed in the morning; it helps the morning orthostatic drop that catches many patients.

Salt Intake

Most adults are told to limit salt for blood pressure reasons. Orthostatic patients usually need more, not less. Aim for 6 to 10 grams of sodium per day (about 2 to 4 teaspoons of table salt), unless you have heart failure, kidney disease, or supine hypertension that makes high salt risky. Salt helps the body retain water and maintain blood volume. Salty snacks (pretzels, broth, pickles) are practical sources. Salt tablets are an option for patients who can’t get enough from food.

Counter-Pressure Maneuvers

When you feel symptoms coming on, several maneuvers can quickly raise blood pressure and abort an episode:

Leg crossing while standing: cross one leg over the other and squeeze. Hand gripping: clench both hands and pull them apart firmly against each other. Toe raises: rise up on your toes a few times to activate the calf-muscle pump. Squatting: drop into a squat or sit on the floor. Bending forward: lean forward at the waist while standing.

These maneuvers work because they raise pressure inside the chest and abdomen, which pushes blood back to the heart. Practice them at home so they feel natural when you need them.

Compression Garments

Graduated compression stockings (pressure highest at the ankles, decreasing up the leg) help by reducing blood pooling. Knee-high stockings at 20 to 30 mmHg pressure are often enough. Thigh-high or waist-high stockings are more effective for severe cases. An abdominal binder helps when significant blood pools in the abdominal vessels. Stockings should be put on before you get out of bed in the morning, when blood hasn’t yet pooled.

The brand I recommend to my own patients is JOBST. You can find the full line at the JOBST compression sock store on Amazon. Start with 20 to 30 mmHg and work your way up to 30 to 40 mmHg as you get used to them. One honest warning: stockings this snug are a workout to pull on, and that’s the single most common reason patients abandon them. A pair of donning gloves and a donning device solve most of the struggle. The video below shows how the donning device works.

Sleep Position

Elevating the head of the bed by 4 to 6 inches reduces overnight fluid shifts and can improve morning orthostatic tolerance. The elevation also lowers supine blood pressure, which matters for patients who have supine hypertension along with their orthostatic hypotension. Use blocks under the head-end legs of the bed rather than just stacking pillows; stacking pillows often slides out and undoes the effect.

Slow Position Changes

Sit on the edge of the bed for a full minute before standing. Wait for the lightheadedness to settle before walking. The few seconds of patience prevent a lot of falls.

Avoid Heat

Hot showers, hot tubs, saunas, and hot environments all cause blood vessels to dilate, which worsens orthostatic hypotension. Use lukewarm showers. Sit on a shower bench if standing in the shower is risky. Avoid sun exposure during the hot part of the day in summer.

Eat Smaller Meals

Large meals shift blood flow to the gut and can cause postprandial hypotension (a blood pressure drop after eating). Smaller meals more often help. Avoid heavy carbohydrate loads, which seem to produce the biggest postprandial drop.

Avoid Alcohol

Alcohol dilates blood vessels and worsens orthostatic hypotension. Eliminate or sharply limit alcohol, especially during the day.

Exercise (Carefully)

Recumbent or seated exercise (rowing machine, recumbent bike, swimming) maintains conditioning without triggering orthostatic symptoms. Avoid sudden upright exertion when symptoms are active. As tolerance improves, gradually add upright exercise (treadmill walking, elliptical) while staying near a support.

What Are the Prescription Options?

Several prescription medications help when lifestyle measures aren’t enough. Midodrine is the first-line FDA-approved drug for orthostatic hypotension. Droxidopa is approved for neurogenic orthostatic hypotension. Fludrocortisone helps the body retain salt and water. Pyridostigmine amplifies the remaining autonomic responses. Each has tradeoffs and the right choice depends on your specific picture.

Midodrine

A selective alpha-1 receptor agonist that tightens blood vessels. Taken 3 times a day, spaced about 4 hours apart, starting at 2.5 mg and titrating up to 10 mg per dose. The last dose should be at least 4 hours before bedtime, because midodrine can cause supine hypertension that’s worst at night. Side effects include scalp tingling (a characteristic feeling that the medication is working), goosebumps, and urinary retention in men.

Droxidopa

A synthetic precursor of norepinephrine. The body converts it to norepinephrine, which raises blood pressure. Especially useful in neurogenic orthostatic hypotension. Taken 3 times a day during the day, with the last dose at least 5 hours before bedtime to limit supine hypertension. Side effects can include headache, dizziness, and supine hypertension.

Fludrocortisone

A synthetic mineralocorticoid hormone that signals the kidney to retain salt and water, expanding blood volume. Taken once daily, typically 0.1 mg, with titration up to 0.2 mg or rarely higher. Requires regular monitoring of potassium and blood pressure. Can worsen heart failure and contribute to supine hypertension.

Pyridostigmine

A cholinesterase inhibitor (the same drug class used for myasthenia gravis) that amplifies the autonomic system’s remaining responses. Useful for patients with partial autonomic function. Taken 30 to 60 mg two to three times a day. Side effects include nausea, diarrhea, and increased salivation.

Atomoxetine

A norepinephrine reuptake inhibitor (originally developed for ADHD) that has shown benefit in some autonomic dysfunction patterns. Usually 18 mg per day. Less established than the other agents but useful in selected cases.

Combination Therapy

Severe cases often need more than one drug. A common combination is midodrine plus fludrocortisone, with pyridostigmine added if there’s residual autonomic function. Droxidopa is sometimes used in place of or in addition to midodrine. The team titrates the combination to balance standing blood pressure against the risk of supine hypertension.

How Do You Manage Supine Hypertension?

Supine hypertension (high blood pressure when lying down) is the flip side of orthostatic hypotension and develops in about half of patients with neurogenic orthostatic hypotension, especially those on treatment. Management requires balancing standing pressure (which needs to be high enough to function) against supine pressure (which shouldn’t be high enough to cause organ damage). Approaches include elevating the head of the bed, careful timing of medications, short-acting antihypertensives at night, and occasionally transdermal nitroglycerin patches at bedtime.

Why It Happens

The same drugs and conditions that raise standing blood pressure tend to raise lying-down blood pressure too. Patients on midodrine, droxidopa, or fludrocortisone often have pressures of 160 to 200 systolic when they go to bed. Over years, this contributes to cardiovascular risk.

Head-of-Bed Elevation

Raising the head of the bed by 6 to 9 inches uses gravity to lower supine pressure modestly. It also reduces overnight fluid shifts that worsen morning orthostatic hypotension. This is the simplest and safest intervention.

Timing Medications

Take orthostatic medications during the day only, with the last dose at least 4 to 5 hours before bedtime. Avoid taking blood pressure-raising medications close to sleep.

Bedtime Short-Acting Antihypertensives

A small dose of a short-acting blood pressure drug (clonidine, hydralazine, or low-dose nifedipine) at bedtime can blunt the overnight pressure rise. The dose has to be small enough not to cause symptomatic morning hypotension when you stand up.

Transdermal Nitroglycerin

A small nitroglycerin patch applied at bedtime and removed in the morning can lower supine pressure during the night. The patch is removed before getting out of bed to avoid worsening morning orthostatic symptoms.

Avoiding Snacks Before Bed

Eating raises blood pressure temporarily. Avoid late-evening snacks if supine hypertension is a concern.

How Do You Prevent Falls and Injuries?

Most of the injury from orthostatic hypotension comes from falls. Reducing falls is one of the most important parts of management. The toolkit includes home safety modifications (remove rugs, improve lighting, install grab bars), walking aids when needed, physical and occupational therapy, vision and hearing optimization, vitamin D adequacy, and emergency alert systems for patients living alone.

Home Safety Walk-Through

Get an honest look at your home for fall hazards. Remove throw rugs. Add non-slip mats in the bathroom. Install grab bars next to the toilet and in the shower. Improve lighting, especially nightlights for getting up at night. Make sure stairs have sturdy handrails on both sides. Move frequently used items to waist-height shelves so you don’t have to bend down or reach up.

Walking Aids

A cane or a walker is a tool that prevents broken hips, not a sign of giving up. If your team recommends one, use it. The fall you prevent is worth the slight inconvenience.

Physical and Occupational Therapy

A physical therapist can work on balance, gait, and strength, all of which reduce fall risk. An occupational therapist can do a home safety evaluation and recommend changes specific to your living situation.

Vision and Hearing

Get an annual eye exam. Address cataracts when they affect function. Get hearing aids if you need them; poor hearing is a risk factor for falls.

Vitamin D

Vitamin D deficiency contributes to muscle weakness and increases fall risk. Most adults over 65 benefit from supplementation; check your level if you haven’t recently.

Medication Review (Again)

Beyond the orthostatic-causing drugs, watch out for sleeping pills, sedating antihistamines, opioid pain medications, and benzodiazepines, all of which add to fall risk.

Emergency Alert System

A wearable medical alert button is worth it for patients living alone with orthostatic symptoms. The few minutes between a fall and getting help can make a substantial difference in outcomes.

When Should I Worry?

Most orthostatic episodes are uncomfortable but not emergent. Call your cardiologist or primary care doctor within a day for new or worsening orthostatic symptoms, any fall, new chest pain or shortness of breath with episodes, new neurological symptoms, or a sense that the medication plan isn’t working. Go to the ER for syncope with injury, syncope with chest pain or shortness of breath, sudden severe symptoms different from your usual pattern, or any signs of stroke.

When to Call the Office

Within a day for: a fall with or without injury; new or worsening symptoms despite the current treatment plan; new chest pain, palpitations, or shortness of breath during an episode; new fatigue or weakness; new neurological symptoms (weakness, numbness, trouble speaking); change in medications by another provider that may interact with the orthostatic plan.

When to Go to the ER

For: fainting with injury (especially head trauma); fainting with chest pain or shortness of breath that doesn’t settle; sudden severe symptoms different from your usual pattern; signs of stroke (sudden weakness, slurred speech, vision loss, severe headache); blood in stool, vomit, or urine (which may be the cause of acute volume depletion); fever with symptoms.

What’s Routine and What’s Not

A typical orthostatic episode that resolves quickly with sitting or lying down is routine and doesn’t need same-day care. Falls without injury, even multiple in a short period, need a routine call but not an ER visit. Anything new, severe, or progressive deserves more urgent attention.

Common Questions Patients Ask Me

Will this go away on its own?

It depends on the cause. Medication-induced orthostatic hypotension often resolves completely when the offending drug is reduced or stopped. Dehydration-related cases resolve when fluids are restored. Cases from progressive neurodegenerative conditions like Parkinson’s or multiple system atrophy don’t go away, but they’re often manageable.

Is it the same thing as low blood pressure?

Not exactly. Some people simply have low resting blood pressure (a systolic of 90 to 100) without any symptoms. Orthostatic hypotension is a specific drop in pressure on standing, with symptoms.

Why does it happen worse in the morning?

Overnight, you lose fluid through breathing and through urination. Blood volume is at its lowest first thing in the morning. The autonomic system is also at its sleepiest. The combination produces the morning peak in symptoms. Drinking a large glass of water before you get out of bed, putting on compression stockings before standing, and rising slowly all help.

Can I still exercise?

Yes, and you should. Reconditioning improves orthostatic tolerance over time. Start with recumbent or seated exercise (rowing, recumbent bike, swimming). Gradually add upright exercise near a support. Avoid sudden upright exertion when symptoms are active.

Should I increase my salt and water?

Almost always yes, unless you have heart failure, kidney disease, or another condition that limits salt or fluid intake. Discuss the right targets with your team. 2 to 3 liters of water and 6 to 10 grams of salt is a common starting point.

Can I drive?

If you have well-managed orthostatic hypotension without fainting episodes, yes. If you’ve had any episode of fainting at the wheel or while transitioning into the car, no, until the team clears you. Driving regulations vary by state.

Is alcohol off-limits?

Sharply limit, especially in the daytime. Alcohol dilates blood vessels and worsens orthostatic hypotension. A small glass of wine with dinner, if your team agrees, may be tolerable for some patients.

What if my blood pressure is high lying down but low standing up?

This is supine hypertension plus orthostatic hypotension, a common combination in patients with neurogenic orthostatic hypotension on treatment. Management involves head-of-bed elevation, careful medication timing, and sometimes a small dose of a short-acting antihypertensive at bedtime.

Will I need this treatment forever?

For non-neurogenic causes (medications, volume depletion), often no. For neurogenic causes from progressive autonomic conditions, usually yes, with adjustments over time.

Is this related to fainting from a sudden scare?

No. That’s vasovagal syncope, which is a reflex response to a trigger (pain, fear, sight of blood, prolonged standing in heat). Orthostatic hypotension is a postural drop in pressure that doesn’t depend on a specific trigger.

Why did my doctor send me to a cardiologist for this?

Because the testing and treatment overlap with our field. Cardiologists handle blood pressure problems, autonomic testing, and the medications used to treat orthostatic hypotension. In many cases, a neurologist also gets involved, especially for suspected Parkinson’s, multiple system atrophy, or pure autonomic failure.

Can my fitness tracker tell me when I have it?

Some watches and patches can measure standing heart rate and rough blood pressure trends. The data is suggestive but not diagnostic. A proper bedside orthostatic vital sign test is the standard.

How Should I Plan My Day?

A few practical adjustments make a big difference. Start the day with a large glass of water before you get out of bed. Put on compression stockings before standing. Rise slowly and sit on the edge of the bed for a minute. Take medications at the times your team specified. Eat smaller meals. Stay out of the heat. Schedule demanding activities for afternoon, when most patients tolerate standing better.

Morning Routine

Drink a large glass of water (about 16 ounces) before getting out of bed. Put on compression stockings while still in bed. Sit on the edge of the bed for a full minute. Stand slowly, using a support. Take morning medications with another glass of water. Eat a small breakfast (large breakfasts can trigger postprandial hypotension).

Daytime Strategy

Drink fluids steadily across the day. Eat smaller meals more often. Avoid prolonged standing tasks in the morning; save them for later. Wear loose, breathable clothing. Avoid hot showers and hot environments. Use counter-pressure maneuvers when you feel symptoms coming on.

Evening Routine

Have your last dose of midodrine, droxidopa, or fludrocortisone at the time your team specified (typically 4 to 5 hours before bed). Eat a moderate dinner. Avoid late snacks if supine hypertension is a concern. Take any bedtime antihypertensive if prescribed for supine hypertension. Sleep with the head of the bed elevated.

Travel and Special Situations

Long flights: stay hydrated, walk the aisle every hour, wear compression stockings. Hot environments: schedule travel during cooler hours, use shaded routes, sit when symptomatic. Eating out: avoid alcohol, eat moderately, sit for a while after the meal before standing.

Common Medications That Cause Orthostatic Hypotension

Lifestyle Measures and What They Do

Prescription Medications for Orthostatic Hypotension

A Final Note From Me

Orthostatic hypotension is a common, often treatable, frequently underrecognized condition. The patients who do best are the ones who understand what’s happening, take the lifestyle measures seriously, and stay in touch with their team about what’s working and what isn’t.

The first step is always the medication review. Most cases I see in clinic resolve substantially once we identify and remove the contributing drugs. The second step is consistent attention to water, salt, compression, and slow position changes. These aren’t glamorous interventions, but they make a measurable difference in symptoms and falls.

Prescription medications are useful when lifestyle isn’t enough. Midodrine, droxidopa, fludrocortisone, and pyridostigmine each have their place. The trick is to balance standing blood pressure against the risk of supine hypertension, which means careful timing of every dose.

Falls are the most consequential complication. A broken hip in an 80-year-old changes the rest of that person’s life. A walker is a tool, not a sign of weakness. A grab bar in the bathroom is prevention. Take these tools seriously when your team recommends them.

If you’ve been told you have orthostatic hypotension, the diagnosis usually points to a specific cause and a specific path forward. The conversation to have with your team is “what’s likely causing this, and which of the menu of fixes are right for me?” Get answers to both questions and you’ll have most of what you need to manage the condition well.

If you have questions about orthostatic hypotension, suspect you have it, or have already been diagnosed and want help thinking through the management plan, our office can help.
