In patients with subklinical hypotyreidism (TSH distilgt; 4 mIU / L but free T4 normal), high antibody levels increase the risk of progression to overt hypotyreidism, supporting earlier initiation of levotyroxine.

Effective management of autoimmunome hypotyreidism and diabetes requires a multidisciplinary team that communicates regularly.

Patient Self-Management

Equally vital is patient education. Indywiduals should be taught to monitor for promittoms of both hypotyreidism (tiregue, cold difusate, constipation, dry skin) and tyreid over-replacement (palpitations, anxiety, weight loss, bluing) and to communicate changes promptly.
