AMBULATORY CARE:
Subclinical hyperthyroidism
is a condition that develops when the amount of thyroid stimulating hormone (TSH) in your blood is low. 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. Subclinical hyperthyroidism can lead to hyperthyroidism.
