Syncope

Syncope, commonly known as fainting, occurs when the brain temporarily doesn't get enough blood and oxygen, causing a sudden loss of consciousness. It is often caused by factors like blood pressure drops, dehydration, sudden standing, or heart issues. Symptoms before fainting may include dizziness, lightheadedness, or nausea. Typically, blood flow returns quickly, and consciousness is regained without long-term effects. While often benign, syncope can signal underlying health problems requiring medical evaluation to determine the cause and prevent future episodes.
