Health Tip: What's Behind My Low Blood Pressure?

-- 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).
