Reliable health information concerning hypothyroidism is available online at websites such as Mayo Clinic, WebMD and MedlinePlus. Brochures, answers to frequently asked questions and patient support links are available through the American Thyroid Association website.
Hypothyroidism is a condition that causes the thyroid gland to under-produce certain hormones, according to Mayo Clinic. In early stages, hypothyroidism does not normally cause symptoms. In later stages, obesity, joint pain and heart disease can occur. Hypothyroidism directly affects the normal chemical reactions that occur in the body. If detected, modern medicine makes treating hypothyroidism a very treatable condition with synthetic thyroid hormone.
