Fainting happens when the blood pressure falls and there is a risk of insufficient blood being pumped to the brain.

Fainting is nature's way of placing the body in a position that is more likely to help raise the blood pressure back to normal. It occurs when people have had to stand still for a long time; (the active pump movement of the calf muscles is not being used to assist in blood flow).

It is not uncommon in pregnancy or after missed meals, the latter also involving a drop in blood sugar levels. Lowering the head or lying the patient down and raising the knees is normally sufficient to aid recovery. Resting for at least 10mins is important to allow the blood pressure to return to normal.
