(HealthDay News) -- Many people worry about high blood pressure and how to bring it under control. But low blood pressure also can be a medical problem, perhaps leading dizziness, fainting or fatigue.
The U.S. National Library of Medicine lists these common causes of low blood pressure (medically called hypotension):
- A side effect of medications, such as certain antidepressants, diuretics, painkillers or heart medicines.
- Alcohol use.
- Heart failure or heart attack.
- Dehydration.
- A severe allergic reaction (anaphylaxis).
- Advanced diabetes.
- Going into shock.
- Irregular heartbeat (arrhythmia).
