Lightheadedness

Medically reviewed by Drugs.com. Last updated on Oct 6, 2024.

Lightheadedness is the feeling that you may faint, but you do not. Your heartbeat may be fast or feel like it flutters. Lightheadedness may occur when you take certain medicines, such as medicine to lower your blood pressure. Dehydration, low sodium, low blood sugar, an abnormal heart rhythm, and anxiety are other common causes.
