What is Restless Legs Syndrome (RLS)?

RLS, also known as Willis-Ekbom disease, is a condition that affects the nervous system, causing an overwhelming urge to move the legs. Individuals with RLS often experience the following sensations:

  • Discomfort
  • Tingling
  • Crawling sensations in their legs

These symptoms tend to worsen during periods of rest, particularly in the evening or at night. This makes it challenging for sufferers to obtain a good night’s sleep.

Genetic factors

Research indicates that RLS can run in families, suggesting a genetic component. Specific gene variants may increase the risk of developing RLS.

Dopamine dysfunction

Dopamine is a neurotransmitter that plays a crucial role in regulating movement. Imbalances in dopamine levels in the brain may contribute to developing RLS symptoms.

Iron deficiency

Insufficient iron levels in the brain may disrupt normal dopamine signaling and lead to RLS. Iron supplementation or dietary changes may be beneficial for individuals with RLS.

Other underlying medical conditions

One condition that can be associated with RLS is varicose veins. Varicose veins are enlarged, twisted veins that commonly occur in the legs. They can cause discomfort, pain, and a heavy or achy feeling in the legs. While varicose veins and RLS are distinct conditions, some individuals with varicose veins may also experience RLS symptoms. If you have varicose veins and are experiencing restless legs, it is important to consult a varicose veins El Paso. Their vein specialist can provide a proper evaluation and guidance on managing both conditions effectively.

RLS can also be associated with other medical conditions, such as:

  • Peripheral neuropathy
  • Diabetes
  • Pregnancy

Treating these underlying conditions may help alleviate RLS symptoms.
