Pregnant women also have a higher likelihood of having night leg cramps. Several conditions, such as kidney failure and diabetic nerve damage, are known to cause night leg cramps. But if you have one of these, you're most likely aware of it and have symptoms other than night leg cramps.

If you haven't already, you will probably experience leg cramps at some point in your life. They can hit at the worst possible moments; whether you're lying in bed at night or taking a run on the treadmill, that sharp stabbing pain can feel totally debilitating. If leg cramps, also called charley horses, persist, they can become even more irritating, perhaps knocking you off your typical exercise or sleep routine. A leg cramp is a sharp, sudden contraction or tightening of the muscle in the calf, which usually lasts a few seconds to a few minutes.

If a cramp does hit, you can ease it in the moment by stretching the muscle gently. To find a long-term solution to leg cramps, however, you might need to take a closer look at their many potential causes. To keep leg cramps at bay, make sure you're nourishing your body and getting enough rest.

You'll also want to rule out any underlying issues that could be contributing to leg cramping, such as peripheral artery disease or thyroid issues. See a doctor when cramps prevent you from exercising, or if they seem to happen spontaneously without a trigger. Here, experts weigh in on the major reasons you might be experiencing leg cramps, so you can keep those muscles free of charley horses for good.

One of the classic causes of leg cramps is dehydration. Peterson, PhD, research assistant professor in the department of physical medicine and rehabilitation at the University of Michigan Medical School, "especially during the summer months, in the heat without enough liquid. It may be that fluid depletion causes nerve endings to become sensitized, "triggering contractions in the space around the nerve and increasing pressure on motor nerve endings," he says.

This depletion is exacerbated by hot conditions or exercising, since you lose more fluid through sweat. It's not just water that you sweat out.

Lost electrolytes can also contribute to leg cramping. If you're low in certain electrolytes and other minerals, that imbalance can trigger spontaneous cramping. An imbalance in sodium, calcium, magnesium, or potassium could all lead to leg cramping, says Gerardo Miranda-Comas, MD, associate program director of the sports medicine fellowship at the Icahn School of Medicine at Mount Sinai.

Sports drinks can help reduce cramps thanks to their sodium, as can eating wisely. Bananas, sweet potatoes, spinach, yogurt, and nuts are rich in those muscle-friendly minerals and may ward off the deficiencies that could cause leg cramps. Pregnancy increases a woman's risk for leg cramps, especially during the second and third trimesters. If you're pregnant and experiencing leg cramps , stay hydrated and consider taking a magnesium supplement —with your doctor's approval.

Independent of an exerciser's hydration status, many experience leg cramping due to overuse. Rest and stretching is extra important in these situations. When you're trying to kick your routine up a notch—increasing your biking mileage, starting to swim for triathlon training —your muscles aren't automatically used to the new intensity and movement. Miranda-Comas explains. You may be more prone to leg cramps when you're already overtired. You might be more lax in your diet or forget to hydrate effectively, or, if your body hasn't had enough time to properly recover from your last bout of exercise, your muscles might already be in rough shape.

Miranda-Comas says. In other words, a tired muscle loses more nutrients than it uses, so it's not functioning at its peak. Nighttime or nocturnal leg cramps, which affect more than half of adults , can also be triggered by tiredness. Sontag explains. Muscles were made to move, contract, and rest, so if you're doing anything out of the ordinary—sitting at a conference all day, standing in line at an amusement park—you might experience some leg cramping.

Standing for a prolonged period of time can understandably contribute to muscle fatigue, which in turn can cause cramping, Dr. Sontag says. But too much sitting isn't necessarily better. Prolonged sitting "may predispose the muscles to malfunction," he explains, as the muscle fibers may become hyperactive.

When the muscle is "on" and can't relax, you end up getting a cramp. If you get leg cramps from standing, make sure to take a seat before your muscles feel too tired. And if you cramp from sitting for long periods of time, try to spend at least a couple of minutes walking around per hour that you're seated. If there's no obvious cause of your leg cramps, then you might want to take a look at any recent additions to your medication list, Dr.

Diuretics, a class of medications used to lower blood pressure , may trigger cramps because they deplete the body of fluid and salts, he explains. Other medications that may cause leg cramps include osteoporosis drugs like raloxifene and teriparatide; intravenous iron sucrose used to treat anemia ; asthma medications like albuterol; conjugated estrogens used to treat menopause symptoms ; and pain meds like naproxen and pregabalin.

Commonly prescribed statins are also associated with muscle cramps in general, he adds. Talk to your doctor if you started taking a new medication at the onset of your leg cramps; Dr. Sontag says he is usually able to find an alternative medication for his patients. If your leg cramps seem spontaneous and not exercise-related, it's important to see your doctor to rule out underlying concerns.

Some, for instance, "those that affect how the body moves electrolytes," Dr. Miranda-Comas says, can cause leg cramps. Others, like peripheral artery disease , when cholesterol clogs blood vessels in the legs, affect blood flow.

PAD can trigger cramps since there may not be enough blood getting to the legs. Leg cramps can also be a symptom of the nervous system disorder multiple sclerosis. Some people with MS experience spasticity, which can include a range of involuntary muscle spasms and twitches, as well as leg cramps.

Spasticity might feel like a mild tightness or tingling in the muscles to some people or more severe cramping and pain to others. Left untreated, spasticity can cause frozen or immobilized joints, so talk to your doctor if you have symptoms of MS. Much like overexcited nerves can cause overuse-related leg cramps, nerves that malfunction for other reasons can lead to cramping too. Osteoarthritis , the most common type of arthritis, is usually categorized by stiff and achy joints.

But people with the painful condition may also experience muscle spasms and leg cramps. These leg cramps are usually linked to osteoarthritis of the spine, which, when severe, could lead to pinched nerves or other nerve damage.

Too-high blood sugar levels in people with type 2 diabetes can lead to damage to the nerves in the legs, feet, arms, and hands called diabetic peripheral neuropathy. This nerve damage often leads to feelings of numbness or tingling, but it can also produce muscle twitching and full-blown leg cramps when the nerves in the legs aren't functioning properly. Diabetes treatment can help prevent any further nerve damage, but a doctor might recommend pain medication or anticonvulsant drugs to tamp down the leg cramps.

Thyroid conditions may also contribute to leg cramps, Dr. People with hypothyroidism produce too little thyroid hormone, and overtime that deficiency can damage the nerves that send signals from your brain and spine to your arms and legs. Some people with underactive thyroids will feel tingling or numbness in their muscles, while others might experience leg cramps.

Always check with a doctor if you have unresolved leg cramps, especially with adequate nutrition, hydration, and stretching.
