Thyroid disease and fibromyalgia: Another study concluded a casual relationship between both
In a study by Bazzichi and their colleagues, they observed that patients suffering from thyroid autoimmunity disorder have higher risks of fibromyalgia. In their clinical test, 52 patients afflicted with autoimmune thyroid diseases were observed together with 37 patients with fibromyalgia. A standard clinical assessment survey and pain indicator test was used for the population of patients observed, and ultimately categorized them based off of their levels of pain, fatigue, muscle spasms, restless sleep, tension headaches, and mood disorders. A comorbidity with fibromyalgia and another thyroid disease known as Hashimoto's thyroiditis (HT) was found in a large number of patients, with or without subclinical hypothyroidism. As a result, they have concluded that there is a relative causal relationship between fibromyalgia and thyroid autoimmunity diseases that may be a little bit more than cause and effect.
