A leg cramp is a sudden and involuntary contraction of one or more muscles. Though generally harmless, muscle cramps can cause severe pain and make it temporarily impossible to use the affected muscle.

Leg cramps may occur due to any of the following reasons:

• Dehydration:

Inadequate consumption of fluids is the most common cause of cramps. It is essential to drink plenty of fluids after a workout and during the summer to avoid dehydration and painful leg cramps.

• Inadequate blood supply:

Narrowing of the arteries that deliver blood to the leg muscles reduces their functionality and increases the risk of recurrent leg cramps. Consult your doctor if you experience frequent leg cramps.

• Electrolyte imbalance:

The muscular contraction and relaxation mechanism requires a certain balance of sodium, potassium, magnesium, and calcium. Consuming a healthy, well-balanced diet rich in fresh vegetables and fruits can effectively prevent leg cramps.

• Physical overload:

Over-exertion of the body results in muscle fatigue, which increases the risk and occurrence of leg cramps.

• Medications:

Leg cramps can potentially be a side effect of certain prescription drugs such as diuretics, conjugated estrogens, and statins. Consult a physician if you believe your leg cramps are a side effect of the medications you are prescribed.

• Inappropriate footwear:

Wearing shoes that don’t fit or support your feet well can cause muscle fatigue and cramps.
