Restless legs syndrome (RLS) causes an urge to move the legs due to a disorder of the part of the nervous system. It is also considered as a sleep disorder because it usually interferes with sleep.
Causes of Restless Legs Syndrome
Doctors do not know the cause of restless legs syndrome in most cases; however, genes play a role as they suspect. Nearly half of people with RLS also have a family member with the condition.
Other factors associated with the development or worsening of restless legs syndrome include:
- Chronic diseases. Certain chronic diseases and medical conditions, including iron deficiency, Parkinson’s disease, kidney failure, diabetes, and peripheral neuropathy often include symptoms of RLS.
- Medications. Some types of medications, including antinausea drugs, antipsychotic drugs, some antidepressants, and cold and allergy medications containing sedating antihistamines, may worsen symptoms.
- Pregnancy. Some women experience RLS during pregnancy, especially in the last trimester. Symptoms usually go away within a month after delivery.
Other factors, including alcohol use and sleep deprivation, may trigger symptoms or make them worse.
