Syncope, commonly known as fainting, is a temporary loss of consciousness caused by a decrease in blood flow to the brain. This condition can occur due to various factors, including dehydration, low blood sugar, or standing up too quickly. It typically lasts for a short period, and most individuals recover quickly without medical intervention. During a fainting episode, a person may feel lightheaded, dizzy, or weak before losing consciousness. It is important to identify the underlying cause of syncope, as it can sometimes indicate a more serious health issue, such as a heart condition or neurological disorder.
