Fainting occurs when you lose consciousness briefly as a result of your brain not getting enough oxygen. Most fainting will pass quickly and won’t be serious, but in some cases, it may be linked to a serious health disorder involving the heart. If you faint more than once, you should contact your GP or healthcare professional as soon as possible.
Here is everything you need to know about fainting from the home doctor experts at House Call Doctor.

What to do if someone faints?
Firstly, you need to encourage blood flow to their head by raising their feet above the level of their heart or have them sit with their head between their knees. Loosen any tight clothing, belts or collars and have the person stay lying down for at least 10 to 15 minutes. Try to cool the person down with a drink of water ifs possible.
