Hypothyroidism in elderly patients.

Hypothyroidism is an endocrine condition found in elderly patients that is often confused with normal changes associated with aging. Consequently, the disorder may be quite advanced before it is diagnosed and treated. Depressed T4 and elevated TSH levels confirm primary hypothyroidism. Patients are required to take levothyroxine for the rest of their lives. Myxedema coma, a life-threatening complication of hypothyroidism, occurs primarily in elderly women and requires immediate treatment to prevent death. Recovery and stabilization may take six to eight months.
