A individual fainting is known as syncope in medical terms. It normally occurs when the brain receives insufficient blood supply. When blood pressure is too low and the brain isn’t getting enough oxygen, this can happen. Syncope is usually a sign of a more serious medical condition.
How does syncope occur?
For the brain to receive oxygen and glucose, it needs continuous blood flow. The reticular activating device, which is located in the brain stem, must be switched on for a person to be awake. At least one of the brain’s hemispheres must also be involved. If the reticular triggering system lacks blood flow or both hemispheres of the brain become inactive due to a lack of oxygen or glucose, fainting occurs.
