Living with hypothyroidism? Explore treatment options >>



Hyperthyroidism is a condition that develops when the amount of thyroid stimulating hormone (TSH) in your blood is high. TSH is made in the brain and controls how much thyroid hormone is made. Thyroid hormones help control body temperature, heart rate, growth, and weight.
