Type 2 DM hyperthyroidism is reported to be more common as compared to normal people. In many patients, uncontrolled hyperthyroidism may be the reason for poor glycemic control and recurrent diabetic ketoacidosis. In response to hyperthyroidism gut absorption of glucose is increased along with endogenous glucose production. Randomly selected 100 patients, both male and female with type 2 diabetes mellitus above age of 40 years including newly diagnosed diabetics attending hospital were included in this study. Among the study group of 100 patients 2 patients had high T4 value, 8 patients had high TSH values and 4 patients were low TSH values
