How do you faint?


According to WebMD, fainting is also referred to as syncope and occurs when there is decreased blood flow to the brain, which in turn causes a momentary loss of consciousness and posture. Conditions that trigger fainting include irregular heartbeat and low iron due to anemia. A vasovagal attack is the most common cause of fainting and occurs when blood pressure drops and decreases circulation to the brain.

The Mayo Clinic explains that certain fainting spells occur when the body overreacts to specific external triggers, such as the sight of blood, or emotional triggers, such as stress. Vasovagal fainting spells are typically harmless and in most cases do not require medical treatment, but it is always a good idea for individuals who experience fainting spells to consult with a medical professional to ensure that the fainting spells are not due to an underlying heart condition.

According to MedlinePlus, fainting can occur after a harsh coughing fit, after a strained bowel movement and in individuals who stand in one spot for an extended period of time. Fainting is also triggered by stress, fear or excruciating pain. Additional causes include medications that lead to a drop in blood pressure, seizures and low blood sugar.
