PROPORTION OF THYROID DYSFUNCTION IN TYPE 2 DIABETES MELLITUS

Abstract

Type 2 diabetic patients show thyroid disorders that may aggravate the metabolic imbalance. In this study, we evaluated the prevalence of abnormal thyroid dysfunction in type 2 diabetes mellitus. This prospective study was conducted among 100 diabetic patients (cases) which were compared with age and sex matched 50 non-diabetic control subjects. TSH (Thyroid Stimulating Hormone), Triiodothyronine (T3) and Thyroxine (T4) were measured. Fasting Plasma glucose and Post Prandial blood glucose is also measured. The result of this prospective study showed, the diabetic patients in the present study although clinically euthyroid show a low level of circulating T3 to which the term “ Low T3 syndrome”given. But there is high prevalence of thyroid disorders in the diabetic population in other studies which indicates that the screening for thyroid disease among diabetic patients should be routinely performed.
