Causes of Restless Legs Syndrome

Many people are losing quality sleep because of Restless Legs Syndrome (RLS), a condition that causes irritation in the legs that keeps them from falling asleep. Identifying the underlying cause is essential to finding the most effective treatment and restoring the quality of your sleep.

Nerve-Related Causes of RLS

The symptoms of Restless Legs Syndrome are often caused by a problem with nerve signals, which may result from:

  • Iron deficiency
  • Diabetic neuropathy

If low iron levels are causing RLS symptoms, treatment may be as easy as a daily iron supplement. However, iron supplementation should be monitored by your healthcare provider to prevent iron poisoning.

Drug-Related Causes of RLS

RLS symptoms are often side-effects of a number of common medications, including:

  • Allergy medicines (OTC and prescription)
  • Antihistamines
  • OTC sleep aids
  • Antidepressants
  • Dopamine-receptor antagonists, including anti-nausea medicines

If the symptoms of Restless Legs Syndrome appear on the list of side effects of medicine you are taking, discuss alternative medications or how to safely wean yourself off of medications with your doctor.

Temporary Causes of RLS

RLS is often caused by pregnancy, especially in the last trimester. If RLS symptoms developed during pregnancy, most often they will completely resolve within a month after childbirth, so no treatment is recommended or necessary.
