If you have an urge to move your leg as soon as it comes to a resting position, you may have a condition called restless legs syndrome. It is a neurological problem that can lead to uncomfortable sensations like throbbing and itching and can even compromise the quality of your sleep. Understanding what causes RLS can help you seek the right medical attention In

Causes of RLS

While the restless legs syndrome is quite common in India, the exact cause behind it is still unknown. However, there are a few speculated reasons for the RLS causes, including dopamine deficiency in the basal ganglia, the part of the brain responsible for movement, which requires dopamine for proper functioning.

Some of the speculated RLS causes are:

  • Genetics: RLS can be inherited if one of your parents passes on the genetic predisposition for the condition.
  • Low Iron Levels: Even with normal blood iron levels, low iron levels in the brain can still contribute to RLS.
  • Medical Condition: Certain medical conditions, such as anaemia, diabetes and kidney disease, can lead to secondary RLS, meaning the condition arises as a result of these underlying health issues.
  • Medicines: Some medicines like antihistamines, antinausea and antidepressants can trigger or worsen RLS symptoms.

Conclusion

RLS is a condition that affects many people, but a lack of awareness may prevent it from being recognised as a medical issue. Now that you are informed, ensure that neither you nor anyone in your family has to live with it untreated. While looking for health insurance plans, be sure to check whether it covers conditions like RLS. This is especially important when choosing senior citizen health insurance, as it’s essential to look for comprehensive coverage that includes RLS and other common health concerns. A good policy ensures coverage against a range of medical conditions, including both common and chronic diseases, as well as unexpected health emergencies, providing financial protection and peace of mind.
