Overview

Hypothyroidism is the disease state in human and animals caused by insufficient production of thyroid hormone by the thyroid gland. It affects about 5% of the United Kingdom population over 60 years of age. As of 2006, more than 1% of the United Kingdom population were receiving T₄ (Thyroxine) replacement therapy for hypothyroidism.
