Causes of restless leg syndrome in most patients are unknown. However, it is associated with pregnancy, obesity, smoking, anemia, nerve disease, and many more.
Causes of Restless legs syndrome
- Iron deficiency or improper utilization – many research findings suggest that restless legs syndrome (RLS) is mostly due to the iron deficiency in brain. The brain makes dopamine-using iron, a chemical that controls other brain activities, particularly part of brain that control movement.
- A number of medical conditions can develop RLS these conditions include kidney failure, Parkinson disease, diabetes, rheumatoid arthritis, pregnancy, and iron deficiency.
- Family history - People whose family members have had RLS are more likely to develop it. Thus, genetics may contribute to the improper utilization or lack of iron in the brain that causes RLS.
- Nerve Damage - in the legs/feet or sometimes in the arms/hands may cause or worsen RLS. Other conditions that can cause nerve damage, including diabetes.
- Medication - that may cause RLS, include Antinausea medicines (for stomach upset treatment), Antidepressants, Antipsychotics (for mental health disorders), Antihistamines (for Cold and allergy), and Calcium channel blockers (for heart problems and high blood pressure). RLS symptoms usually get better or may even disappear if the medication is stop that causes RLS.
- Alcohol and tobacco can also cause or worsen RLS symptoms. Symptoms may be relieved or disappear once these substances are stopped.
