Syncope is a medical condition characterized by a sudden, brief loss of consciousness and muscle strength, followed by a rapid and complete recovery. It is also known as fainting or passing out. Syncope is caused by a decrease in blood flow to the brain, usually from low blood pressure. It can be triggered by a variety of factors, including standing for a long period of time, emotional stress, dehydration, and certain medications. Treatment for syncope typically involves lifestyle changes, such as drinking more fluids and avoiding triggers, as well as medications to increase blood pressure.
