Restless Legs Syndrome

While most people might not associate restless legs syndrome (RLS) with a struggle to stay fit, this relatively common but often untreated condition can zap your energy, leaving you with little left to work out, eat right, and generally take good care of yourself.

Could you be among the estimated 1 in 10 people in the U.S. with RLS? It's possible, if these symptoms sound familiar:

• A strong urge to move your legs, accompanied by feelings of discomfort such as itching, creeping, tugging, or pulling. These feelings occur when your legs are at rest, and they subside when your legs are in motion.
• Insomnia or interrupted sleep as a result of the urge to move your legs.

In most cases, the cause of RLS is unknown. Some cases of RLS have been linked to deficiencies of iron, vitamin B, or folate; in these cases, a healthy, balanced diet or supplements can help to relieve symptoms. Sometimes RLS is linked to another health condition, like peripheral neuropathy (loss of sensation or pain, particularly in the limbs, which may be a complication of diabetes or other disorders), impaired circulation (for instance, varicose veins or swelling in the legs), or Parkinson's disease (a nervous system disorder associated with tremors and impaired movement). In these cases, treating the underlying condition can help to alleviate RLS symptoms. RLS may have a genetic component as well, as some cases seem to run in families.

Because certain drugs can aggravate the symptoms, be sure to tell your doctor about all medications and supplements you take. Drugs linked to RLS include antinausea drugs like metoclopramide (brand name Reglan), antiseizure drugs like phenytoin (Dilantin), antipsychotic drugs like haloperidol (Haldol), and some cold and allergy medications.

If you suspect you might have RLS, ask your doctor to evaluate you for this condition. Avoiding caffeine, nicotine, and alcohol may help reduce the symptoms. Prescription medications are also available that can calm the symptoms and help you get a better night's sleep.
