Hypothyroidism
An underactive thyroid gland that doesn't produce enough hormones, slowing metabolism and causing fatigue and weight gain.
Overview
Hypothyroidism occurs when the thyroid gland doesn't produce enough thyroid hormone, which regulates metabolism throughout the body. The most common cause is Hashimoto's thyroiditis (autoimmune), but it can also result from thyroid surgery, radiation, certain medications, or iodine deficiency. Symptoms develop gradually and can be subtle, often attributed to aging or stress before diagnosis. Treatment with thyroid hormone replacement is usually straightforward and effective.
