Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormone.

Thyroid hormone is important for regulating metabolism, energy levels, and overall body functions.

Common symptoms of hypothyroidism include fatigue, weight gain, feeling cold, dry skin, and depression.

Hypothyroidism can be caused by an autoimmune disease called Hashimoto's thyroiditis, iodine deficiency, or certain medications.

Hypothyroidism is diagnosed through a blood test that measures thyroid hormone levels.

Treatment for hypothyroidism involves taking synthetic thyroid hormone medication to replace the hormone the body is lacking.

With proper medication and management, most people with hypothyroidism can lead normal, healthy lives.
