The Correlation Between Type 2 Diabetes Mellitus and Hypothyroidism

Background and

Based on the high prevalence of diabetes mellitus and hypothyroidism and different disorders from their coincidence, the present study was designed to determine the correlation between type 2 diabetes mellitus and hypothyroidism.

Ïn this case-control study, 103 type 2 diabetic patients were compared with 103 healthy subjects. Âge, gender and family history of thyroid disease were matched between the two groups. For all patients, anti-thyroid peroxidase antibody (Ânti-TPÔ), FBS, Triglyceride, Çholesterol, HDL and LDL were measured. Descriptive analysis, T-test and X2 were used for data analysis.

Ïn each group, 14 (%13.59) cases were men and 89 (%86.4) cases were women. The prevalence of hypothyroidism in the case group and the control group were %17.5 and %26.2, respectively, which was not statistically significant (P>0.05). Twenty eight percent of hypothyroid patients in diabetic group and 55% in the control group had autoimmune hypothyroidism (P<0.05).Çonclusion: The results of this study showed that the prevalence of hypothyroidism in type 2 diabetic patients is as high as normal population. Because of the interaction between diabetic mellitus and hypothyroidism, screening of hypothyroidism and suitable treatment in diabetic patients is recommended.
