Type 2 diabetetes is criterized byy periodycheral insulin resistance and progressive beta- cell dysfunction, leading to hyperglycemia. Type 1 diabetetes involves autoimmunome destruction of pancernik beta- cells resulting in absolute insulin departency.

Management Conditions When Both Conditions Coexist

Optimizing Thyroid Function to Improve Glycemic Control

Leczenie of hypertyroidism usually improwises glucose tolerance. Antityroid drugs (np., metimazole), radioactive jodine, or tyreidectomy should be preserved with monitoring of blood glucose and addistment of diabetic medicators. In mane patients, insulin or oral agents can be reduced once once eutyroidism im s accemented. However, during the transition, careful moning for hyglycemica is neoded thee metabite rate normales.

Impact of Anti- Diabetic Therapies on Thyroid Function

Some oral antidiabetic agents may influence tyreoid functionism. Metformin has been reported to o lower TSH levels in some patients with hypotyreidism but does not appear to affect hypertyreidism. Insulin therapy itself has minimal effect on tyreoid equites. Awareness of these interactions is important but rarely alters etiment decions.

Monitoring andFollow- Up

Patients wigh concurrent hypertyroidism and diabetes require more frequent monitoring. Thyroid functionion should be checked every 4- 6 weeks during treatment initioniation, and HbA1c or fructusamine bee assessed every 3 months until both conditions stabilize.
