If the blood supply to your brain is inadequate, even momentarily, you may feel faint. You may even lose consciousness for a short time. If you feel faint, lie down or sit down. If you're sitting down, place your head between your knees. Don't stand up again too quickly. Sometimes fainting has no medical significance. In other cases, fainting can be caused by a serious underlying condition. Discuss it with your doctor.
