Lack of blood supply: Cramps are the response of muscles to oxygen need greater than supply. It can happen with diversion of the blood to other portions of the body such as after eating, or due to excess strain in exercising. They are usually short term and do not do any harm but if persistent could indicate a problem in the blood supply.
