Fainting is a loss of consciousness for a brief period of time, notes MedlinePlus. In most cases, fainting does not pose a serious threat and can be managed by allowing the individual to rest and get fresh air. However, when a person does not get well quickly or has fallen from a great height, the issue should be reported to a doctor immediately.

One of the most common reasons for fainting is dehydration. Due to low levels of fluids in the body, the heart may not be able to pump enough blood to the brain. Drink plenty of water and fluids to avoid fainting caused by dehydration.

Avoid standing for prolonged hours, especially after previously experiencing a fainting spell. Certain medications may trigger fainting spells; follow doctor's instructions when taking medications that are associated with fainting side effects.

Cases of fainting caused by underlying issues such as diseases or other medical conditions can be managed by treating the underlying cause. Doctors take the patient's history and carry out a physical examination to determine the best way to manage the situation.
