What is subclinical hypothyroidism?
Subclinical hypothyroidism is a condition that develops when your thyroid stimulating hormone (TSH) level is higher than normal. TSH is made in the brain and controls how much thyroid hormones are made. Thyroid hormones help control body temperature, heart rate, growth, and weight. Subclinical hypothyroidism can lead to hypothyroidism.
What causes subclinical hypothyroidism?
- A family history of hypothyroidism
- An autoimmune disease, such as inflammation of your thyroid, or Hashimoto disease
- Surgery, radiation therapy, or medicines such as lithium, sedatives, or narcotics

How is subclinical 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 TSH level.
