Evaluation of Thyroid Profile Among The Diabetic Patients in South Indian Rural Population

Both diabetes and thyroid disorders involve dysfunction of the endocrine system. Almost one third of people with type 1 diabetes have been found to have thyroid disease. Since both diseases are parallel and influence one another. Any alteration in thyroid hormones may have further complication such as CAD. Low T₃ syndrome is well established in development of CAD. In the present study we assessed the circulating thyroid hormones and glycemic status among Diabetic population. T₃ levels are low in both Type I and II diabetes, and are directly correlated with poor glycemic control. Among the diabetic population women are worse affected than men. In conclusion, many diabetics showed a low T₃ levels, suggesting that there may be impairment in the extrathyroidal conversion of T₄ to T₃ (5' deiodinization) and in turn enhanced by a poor glycemic control. The study reveals that frequent checkup for thyroid hormones are compulsory to prevent further complications.
