What Causes Restless Leg Syndrome?

Hypothyroidism Or Hyperthyroidism

Hypothyroidism or hyperthyroidism and restless leg syndrome often occur together because both conditions are associated with dopaminergic dysfunction. In a study of patients with thyroid conditions, 8.2 percent reported having symptoms similar to those described in RLS. By comparison, the control group without thyroid conditions only have a 0.9 percent prevalence of restless leg symptoms. One-third of the thyroid patients reported their RLS symptoms became completely resolved after their thyroid condition was treated. Hypothyroidism is caused by the thyroid failing to make enough hormones. The condition can also cause depression and slow metabolism. On the other hand, hyperthyroidism occurs when the thyroid is overactive and creates too many hormones. This can lead to an overactive metabolism and potentially serious symptoms.
