What is hypothyroidism?
Hypothyroidism is a condition that develops when the thyroid gland does not make enough thyroid hormone. Thyroid hormones help control body temperature, heart rate, growth, and weight.

- Autoimmune disease, such as inflammation of your thyroid, or Hashimoto disease
- Surgery, radiation therapy, or medicines such as lithium, sedatives, or narcotics
- Thyroid cancer or viral infection
- Low iodine levels
What are the signs and symptoms of hypothyroidism?
The signs and symptoms may develop slowly, sometimes over several years.

How is hypothyroidism diagnosed?
Your healthcare provider will ask about your symptoms and what medicines you take. He will ask about your medical history and if anyone in your family has hypothyroidism. A blood test will show your thyroid hormone level.
