Orthostatic Hypotension

That dizzy feeling when you stand up isn't "just getting older." Discover the root cause and find lasting relief at Healers Clinic Dubai.

What is Orthostatic Hypotension?

Orthostatic hypotension (also known as postural hypotension) is a form of low blood pressure that occurs when standing up from a sitting or lying position. It is characterized by a sudden drop in blood pressure, causing dizziness, lightheadedness, or even fainting.

Why Does It Happen?

When you stand up, approximately 500-800ml of blood pools in the lower extremities. In a properly functioning cardiovascular system, baroreceptors in the carotid arteries and aortic arch detect this drop in blood pressure and trigger the autonomic nervous system to increase heart rate and vascular resistance. In orthostatic hypotension, this compensatory mechanism fails, causing inadequate cerebral perfusion.

Root Causes

Autonomic Neuropathy

Damage to the autonomic nervous system impairs the body's ability to regulate blood pressure

Dehydration

Insufficient fluid intake reduces blood volume, making it harder to maintain pressure when standing

Heart Problems

Heart valve disorders, heart failure, or low heart rate can prevent adequate circulatory response

Endocrine Disorders

Adrenal insufficiency, thyroid disorders, and diabetes can affect blood pressure regulation

Medication Effects

Blood pressure medications, diuretics, and certain antidepressants can cause excessive blood pressure drops

Red Flags

Fainting or loss of consciousness
Chest pain or pressure
Shortness of breath
Severe headache
Persistent dizziness
Signs of stroke

At-Home Strategies

Rise Slowly

Sit at the edge of the bed for a minute before standing

Stay Hydrated

Drink adequate fluids throughout the day

Compression Stockings

Wear compression socks to reduce leg blood pooling

Avoid Large Meals

Eat smaller, more frequent meals

Exercise Regularly

Strengthen leg muscles to help pump blood upward

Frequently Asked Questions

What is the difference between orthostatic hypotension and regular hypotension?
Regular (or absolute) hypotension is consistently low blood pressure regardless of position. Orthostatic hypotension specifically refers to the drop in blood pressure that occurs when standing up, rather than when lying down or sitting.
Can orthostatic hypotension be cured?
The prognosis depends on the underlying cause. If caused by dehydration or medication, it can often be resolved. Chronic causes may require ongoing management. At Healers Clinic, we focus on identifying and treating the root cause for lasting improvement.
Why does standing up make me dizzy?
When you stand, gravity causes blood to pool in your legs. Your body normally compensates by increasing heart rate and constricting blood vessels. In orthostatic hypotension, this compensation is inadequate, leading to reduced blood flow to the brain and dizziness.
