Thyroid disease

Thyroid Disease is a medical condition that affects the function of the thyroid gland, and can in include hyperthyroidism (excess thyroid hormone), hypothyroidism (insufficient hormone), goiter, and thyroid cancer, as well autoimmune thyroid diseases such as Hashimoto's thyroiditis or Graves' disease.

Typically, hypothyroidism is ruled out before the diagnosis of myalgic encephalomyelitis or chronic fatigue syndrome is given. However, there is some evidence to suggest a subset of ME/CFS patients may have subtler thyroid hormone issues.
