Vasovagal syncope, often referred to as a vasovagal response, is caused by a sudden drop in heart rate and blood pressure, leading to reduced blood flow to the brain. This can be triggered by various factors such as stress, pain, prolonged standing, or emotional distress. When the body overreacts to these triggers, it results in fainting or lightheadedness. The condition is generally benign but can be concerning if it leads to injuries from falls.
