Hypothyroidism (Underactive thyroid)
Under-activity of the thyroid gland leads to a decrease in metabolism. This typically happens because of a disease called Hashimoto’s thyroiditis. Symptoms of hypothyroidism can include fatigue, constipation, changes in hair and nails, weight gain, and changes in mood. Hypothyroidism is typically diagnosed based on blood work.
Diagnosis and treatment of Hypothyroidism
Many patients can have fluctuating symptoms, and testing may not reveal significantly abnormal lab results with the first test. Your doctor may run blood tests at different times to try to diagnose this condition. Once the thyroid function is clearly found to be abnormal, medication to help support the thyroid hormone levels is started.
