👉 Syncope is a medical condition where a person's heart rate drops to a low level, causing them to feel dizzy and faint. It can be caused by various factors such as stress, dehydration, or an underlying health issue like low blood pressure. Symptoms may include feeling light-headed, dizziness, nausea, or weakness in one or both legs. If left untreated, syncope can lead to further complications such as heart failure or even death.
