Feeling Dizzy When You Stand Up? It Might Be Orthostatic Hypotension
Have you ever stood up too quickly and felt lightheaded or dizzy? While that can happen to anyone once in a while, if it happens often, it might be more than just getting up too fast, it could be orthostatic hypotension, also known as postural hypotension.
What is Orthostatic hypotension?
Postural hypotension is a condition where your blood pressure drops significantly when you go from lying down or sitting to standing. This sudden drop can lead to symptoms like:
- Dizziness
- Lightheartedness
- Blurry Vission
- Fainting
- Weakness
These symptoms usually appear within a few minutes of standing up and can improve when you lie back down.
Causes of Orthostatic hypotension:
- Dehydration
- Poor oral intake
- Parkinson’s disease
- Autonomic dysfunction
- Adrenal insufficiency
- Diabetic Neuropathy (nerve damage)
- Some medications like those for high blood pressure, depression, or Parkinson’s can contribute to postural hypotension.
Diagnosing the Problem
Orthostatic hypotension is diagnosed by measuring blood pressure and heart rate after the patient has been lying down quietly for about 5 minutes and then again after standing. A fall in systolic blood pressure of ≥20 mmHg or diastolic blood pressure of ≥10 mmHg within 3 minutes of standing confirms orthostatic hypotension. In some cases, further testing may be needed to assess how well your autonomic system is functioning.
How Is It Treated?
Treatment focuses on both managing symptoms and addressing the underlying cause. Options may include:
Lifestyle changes:
- Stand up slowly
- Stay hydrated
- Wear thigh high compression stockings
Medication adjustments:
- Some medications may need to be reduced or stopped
- Others, like midodrine, may be added to help raise blood pressure
Physical therapy and exercise:
- Gentle movements can help improve circulation and strengthen food vessels over time.
Why It Matters
Postural hypotension can lead to serious falls and injuries, especially in older adults. It can also be a sign of an underlying condition that needs attention.
