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

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
