What Causes Leg Cramps in Children?

A muscle cramp or spasm can be defined as an involuntary and sudden muscle contraction. Usually these kinds of muscle cramps are experienced in the legs (commonly known as a "charley horse"). These kinds of leg cramps are generally observed in children. Though the exact cause of a leg cramp is not known, there are some factors which may be partly responsible for leg cramps.

Fatigue

• Muscle fatigue can cause leg cramps in children. Tired and overworked muscles may stiffen and leg cramps may result.

Exercising

• Muscles need time to rest and recuperate. Hence excessive exercising or play may also cause leg cramps in children. Children need to warm up and cool down before and after their exercises to avoid this.

Electrolyte Imbalances

• Electrolyte imbalances may also cause leg cramps in children. This can be controlled by regularly taking calcium and magnesium. Green leafy vegetables are also useful in enhancing the mineral balance in the body.

Dehydration

• Lack of water can cause problems in the transportation of nutrients across the cells and muscles. It may also lead to an access of lactic acid built up in the cells, which can cause cramps.

Obesity

• Obesity may be one of the main causes of leg cramps in children. Obesity causes muscle fatigue due to the additional weight.

Illness

• Leg cramps can also be an indication of serious problems like leukemia and other diseases. See a physician if your child experiences abnormally painful or chronic leg cramps.
