A study on spectrum of thyroid dysfunction in type 2 DM

Abstract

The prevalence of thyroid disease in diabetic patients is significantly higher than in general population. Apart from autoimmune etiology linked to the higher prevalence of thyroid disease in DM, it has also been observed that thyroid function is intrinsically linked to insulin resistance. It has also been stated that common factors simultaneously are responsible for increased TSH levels and insulin resistance. Method of collection of data was done by taking detailed clinical history regarding diabetes mellitus (onset, duration), any history of long term illness, any previous thyroid dysfunction, previous history of any kind of drug therapy, whether the patient was on insulin or oral hypoglycemic drugs was sought. It is seen that out of 110 diabetic patients, 16 (14.55%) patients had subclinical hypothyroidism, 7 (6.36%) patients had overt hypothyroidism, 3(2.73%) patients had overt hyperthyroidism and 84(76.36%) patients were in euthyroid group.
