Background: Diabetes mellitus type2 (T2DM) and thyroid dysfunction (TD) are the
two most common endocrine disorders in clinical practice. The unrecognized TD may
adversely affect the metabolic control and add more risk to an already predisposing
s
cenario for cardiovascular diseases. The objective of this study was to investigate the
prevalence of TD in patients with type2 diabetes mellitus.
Objective: To determine the prevalence and patterns of thyroid dysfunction in
patients with type2 diabetes mellitus.
Material and methods: Study included total 362 subjects (204 type2 diabetic patients
and 158 healthy non diabetic subjects). Agroup of type2 diabetic patients and control group
were evaluated for thyroid dysfunction by testing TSH and FT4 when TSH was abnormal.
The correlation of prevalence of thyroid disorder with gender distribution, age distribution,
duration of diabetes, BMI, treatment, fasting plasma glucose (FPG), serum triglyceride and
serum cholesterol was then done in diabetic patients. The observations and interpretations
were recorded and results obtained were statistically analyzed.
Results: The prevalence of thyroid dysfunction among type2 diabetic patients was
found to be 13,2%. In the control group, the prevalence of thyroid dysfunction was 6,3%.
There was a significant difference between diabetics and control subjects p= 0,031.The
most frequently TD in type2 diabetic patients was subclinical hypothyroidism (8,3%).
Thyroid dysfunction was significantly correlated with gender (women > man), age < 60
years, FPG > 130mg/dl, TG > 150mg/dl and insulin treatment in type2 diabetic patients.
Conclusion: Screening of thyroid dysfunction shoud be done in all Type2 diabetic
patients.
