Leg cramps at night may be the result of over exercising or overdoing daytime activity. Too much activity can lead to muscle fatigue and may lead to cramping later on when you are trying to relax. You also may be at risk if you spend long hours standing on hard surfaces, sitting inactive for long periods, or holding your legs in an awkward position while sleeping or during the day.
Lack of Proper Nutrition
If your diet lacks certain nutrients you may experience painful leg cramps at night. If your diet is deficient in potassium, calcium and other minerals, you are at a higher risk. Being dehydrated and not having enough fluid in your body can be another common cause. The right levels of nutrients and water are necessary for proper muscle function and contraction. If your levels are depleted, your muscles can cramp.
Some medications may list night cramps as a side effect. This includes drugs such as birth control pills, diuretics, statins and steroids. All of these medications can cause cramping, because they may deplete your body's levels of fluid, sodium, potassium, calcium and magnesium. See Medicinenet.com for a complete list of medications that can cause cramping.
Other Medical Conditions
Having a thyroid condition or a neurological disease such as Parkinson's may increase your chances of having nighttime leg cramps. So can living with peripheral artery disease or diabetes. Some medical conditions can hinder your body's ability to get enough oxygen to the muscles, causing them to fatigue and cramp. You also are more prone if you have flat feet or are pregnant. Both may make you walk differently, which can place strain on the muscles of the lower leg and lead to cramping. According to the Mayo Clinic, as we age our chances of experiencing night leg cramps increases.
To help prevent nighttime leg cramps, make sure you stretch before and after vigorous activity and warm up properly. Keeping well hydrated also will help you to minimise your chances of leg cramps at night. If you think your diet may be deficient in certain nutrients, talk with your doctor or a registered dietitian to have them analyse your diet and help you make healthy changes.
