Low Blood Pressure Symptoms & Diagnosis

Symptoms

Symptoms include:

Mild to moderate reduction in brain blood flow:
- Faintness
- Light-headedness
- Dizziness
- Weakness
- Confusion
- Visual blurring
Severe reduction in brain blood flow:
- Fainting or brief loss of consciousness (syncope)

Exercise or having eaten a heavy meal may worsen symptoms.

If you experience any of these symptoms do not assume it is due to orthostatic hypotension. These symptoms may be caused by other health conditions. If you experience any one of them, see your doctor.

Diagnosis

Orthostatic hypotension is diagnosed when symptoms are present and there is a measured reduction in blood pressure while standing, which is relieved by lying down. The underlying cause must be determined on an individual basis.
