Thyroid dysfunction (TD) and diabetes mellitus (DM) are two of the most frequent chronic endocrine disorders with variable prevalence among different populations. This study was conducted to assess the thyroid function in type 2 diabetes mellitus patients in a known area. Material and methods: This study was conducted as a cross-sectional analysis on a sample of 100 individuals who were diagnosed with type 2 diabetes and were over the age of 20. The participants were selected from those who visited the hospital over a span of 4 months. Thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), and insulin resistance (IR) were assessed in all individuals. The subjects were subsequently categorized into hypothyroid, hyperthyroid, and euthyroid groups based on their thyroid profiles. Assessment of results was done using SPSS software. Results: Out of the total of 100 patients, 30 (30%) were diagnosed with hypothyroidism, 6 (6%) were diagnosed with hyperthyroidism, and 64 (64%) were determined to have normal thyroid function (euthyroid). Among people with diabetes, the incidence of thyroid dysfunction was determined to be 36%. Conclusion: Failure to identify thyroid hormone abnormalities can significantly contribute to inadequate management of type 2 DM.
