What causes restless leg syndrome?
Experts are still trying to pinpoint the exact cause of Restless Leg Syndrome (RLS). However, here is what they do know at this point, courtesy of the Restless Leg Syndrome Foundation:
- RLS most often occurs in middle-aged adults but has also been traced back to childhood for some sufferers
- RLS often runs in families
- RLS sometimes appears to be the result of another condition, which, when present, worsens the underlying RLS. This is called secondary RLS
- Up to 25 percent of women develop RLS during pregnancy, but the symptoms often disappear after giving birth
- Anemia and low iron levels can make RLS worse
- RLS is very common in patients who require dialysis for end-stage renal disease
- Damage to the nerves of the hands or feet from any number of causes, including diabetes, contributes to RLS
- Attention Deficit Disorder (ADD) is common in children and adults with RLS
