Prevalence of Thyroid Dysfunction Among Patients with Type 2 Diabetes Mellitus in a Tertiary Care Hospital

Abstract

Objective

To find the prevalence of thyroid dysfunction (TD) among patients with type 2 diabetes mellitus (DM) in a Tertiary care hospital.

Study method

Retrospective hospital based descriptive study in a tertiary care hospital

Study population

All Type 2 DM patients who attended the hospital between the periods of January 2015 to December 2015 were included.

Results

A total of 415 Type 2 DM patients were selected for this study, from which 59.76% (248) were females and 40.24% (167) were males. The mean age of the study sample was 51.82 years (±10.66). From the total 415 study subjects, 20(4.8%), 80(19.3%), 270(65.1%) and 45(10.8%) study subjects belonged to the age group of 20-34, 35-44, 45-64 and ?65 years respectively.

The mean duration of diabetes in the study sample was 8.23 years (±7.28). Among the thyroid dysfunction, commonest type was found to be hypothyroidism (20.14%), followed by Sub clinical hypothyroidism (5.78%). The prevalence of Primary hyperthyroidism and Sub clinical hyperthyroidism are 2.17% and 0.72% respectively. Prevalence of TD among females, 39.1 %( 97), was higher than males, 18.6 %( 31.

Conclusions

Screening of thyroid dysfunctions should be done in all diabetic patients especially in female diabetic population and poor diabetic control.
