Leg Cramps: Causes and What to Do

There is nothing quite like having leg cramps. I can be sleeping soundly one minute and be wide awake and writhing in pain the next. It feels like someone has tied barbed wire around my calf muscle and then put a wrench on both ends. But what are some possible causes?

In my experience, muscle injury due to overuse can certainly cause leg cramps. But one should not just assume that's what it is.

The Mayo Clinic says that during periods of heavier exercise than normal you can become dehydrated, which can cause leg cramps as well. Simply replenishing your body's water supply can alleviate leg cramps that result from dehydration. But dehydration also can result from inadequate fluid intake even during normal daily activity.

Leg Cramps Causes

According to the Mayo Clinic , the depletion of calcium in your body is one of them. But Mayo also states that too little potassium and magnesium can play a role in leg cramps as well. And the depletion of these minerals in the body can be caused by several factors.

For example, the Mayo Clinic says people who take diuretics and blood pressure medications may find their levels of calcium, potassium and magnesium are still not up to par. These medications have a tendency to deplete mineral levels, in spite of efforts to eat foods rich in these minerals.

Leg cramps causes can come from much more serious issues as well. Harvard Medical School says about 30,000 people in America currently suffer with amyotrophic lateral sclerosis (otherwise known as ALS, or Lou Gehrig's disease). About 5,600 people are newly diagnosed every year. Muscle cramps in the legs can be one of the symptoms.

The National Institute of Neurological Disorders and Stroke states that muscle pain, stiffness and cramping in the legs and toes are also symptoms of Parkinson's disease.

Studies through the National Kidney and Urologic Diseases Information Clearinghouse (NKUDIC) show that leg cramps can be the beginning signs of serious kidney malfunction. When kidneys don't function properly, wastes aren't being filtered from the blood in a sufficient manner. The resulting condition is called uremia.

Sometimes leg cramps causes are simply unknown. But if leg cramps should become frequent and persistent, you should not hesitate to see your doctor. There may be a serious underlying cause.

Remedies for Leg Cramps

There are many remedies for alleviating leg cramps causes, but you should do your homework and choose wisely.

One of the most common remedies doctors used to treat leg cramps was quinine, a chemical with medical uses. However, according to Johns Hopkins Health Alerts, quinine can have some serious side effects. It should only be used for its primary purpose: to treat malaria.

Johns Hopkins says that doctors are exploring the use of muscle relaxers, numbing agents and calcium channel blockers as other treatments for leg cramps causes. Johns Hopkins also says diazepam and naftidrofuryl (an antiseizure medication) may be effective, but patients are encouraged to try B-complex vitamins.
