Hypothyroidism is a condition that occurs when the thyroid gland produces an inadequate amount of thyroid hormone. The most common causes of hypothyroidism are iodine deficiency, Hashimoto's thyroiditis, and as a result of treatment for hyperthyroidism. Secondary hypothyroidism may occur if an individual's pituitary gland is damaged, which results in an inability of the body to control thyroid hormone production.
Thyroid hormones are necessary to control metabolism within the body. Consequently, when the thyroid gland does not produce enough thyroid hormones, the effect on the body is far-reaching. Hypothyroidism may result in weight gain, slow metabolism, dry skin, fatigue, depression, migraines, osteoporosis, and a variety of other symptoms. Treatment for individuals with hypothyroidism usually includes thyroid hormone replacement therapy. Social Security does not have a specific disability listing for hypothyroidism. Instead, the agency will evaluate your medical condition under the complications caused by your hypothyroidism and your resulting functional limitations. For instance, if your hypothyroidism has caused heart disease, you would be evaluated under the cardiovascular disability listings.
