Let's talk about Restless Legs Syndrome & Genetics
What is restless legs syndrome?
Restless legs syndrome, also called RLS or Willis-Ekbom disease, is a neurological condition characterized by the uncontrollable urge to move the legs. Scientists believe reduced iron levels in the brain may play a role. Evidence also suggests RLS may be related to dopamine, a chemical messenger in the brain that helps control body movement.
People with RLS tend to experience discomfort in their legs and sometimes other parts of the body as well. Because the urge tends to come when resting or stationary, they can also have trouble sleeping. This lack of sleep can make them tired and affect their ability to concentrate throughout the day.
Is restless legs syndrome genetic?
Genetics does play a role in restless legs syndrome. In addition, people with a family history of RLS have a higher chance of developing RLS themselves.
What impacts my chances of developing RLS?
Genetics are a factor in RLS, but there are also other elements to take into account. For example, RLS tends to be more common as people age.
Restless legs syndrome is also more common in females than in males. Some females develop RLS during pregnancy but for most, symptoms disappear after delivery. Certain types of medications or health conditions like iron deficiency, end-stage kidney disease, and nerve damage can also impact your chances of developing RLS.
Did you know?
Up to 7-10% of the general U.S. population is estimated to have RLS.
