Don ‘ ts: Don ‘ t slap or shake anyone who’s just fainted. Don ‘ t try to give the person anything to eat or drink, not even water, until they are fully conscious.
Fainting happens when you lose consciousness for a short amount of time because your brain isn’t getting enough oxygen. The medical term for fainting is syncope, but it’s more commonly known as “ passing out.” A fainting spell generally lasts from a few seconds to a few minutes.
Most people who faint do not need to go to the emergency room, but for a small minority of people who do faint, the brief loss of consciousness can be a sign that more serious and potentially fatal medical events are on the horizon.
When a person faints, they suffer a brief loss of consciousness. It is recommended that you lay the person down and elevate their feet. Most people will recover quickly after fainting once they lay down because more blood can flow to your brain.
If you see someone faint, lie the person on his or her back and make sure they are breathing. If possible, lift the person’s legs above heart level to aid blood flow to the brain.
Less often, people faint suddenly, without any warning symptoms. Seizures, which are a disturbance of the brain’s electrical activity, and cardiac arrest, in which the heart completely stops beating, can cause loss of consciousness but are not considered fainting.
They may be unconscious for a few seconds — as in fainting — or for longer periods of time. People who become unconscious don’t respond to loud sounds or shaking. They may even stop breathing or their pulse may become faint.
Many different conditions can cause fainting. These include heart problems such as irregular heart beats, seizures, low blood sugar (hypoglycemia), anemia (a deficiency in healthy oxygen carrying cells), and problems with how the nervous system (the body’s system of nerves) regulates blood pressure.
One of the most common reasons people faint is in reaction to an emotional trigger. For example, the sight of blood, or extreme excitement, anxiety or fear, may cause some people to faint. This condition is called vasovagal syncope.
If you do faint, remain lying down for ten minutes. Sit up slowly when you need to get up.
When coming round after a faint, the person often feels awful, sickly and may vomit, or even have diarrhoea. Often there is prolonged fatigue after a faint.
Body’s clock may lead to increased risk for fainting during the nighttime. Summary: The circadian system may contribute to the daily pattern of vasovagal syncope via its influences on physiological responses to changes in body posture. Fainting, or syncope, is quite common.
The medical term for fainting is syncope. When someone loses consciousness, it’s possible that their eyes may roll back into their head before or when they fall down. Typically, an individual is only unconscious for a minute or two after they’ve fainted.
