Introduction: Endocrine disorders pose a major threat to public health. Current research shows that 300 million people are suffering from thyroid disorders globally and 42 million among them reside in India. Objective: Our objective is to find the prevalence of thyroid disorders in rural population of Gurgaon, Haryana. Materials and Methods: This study was conducted in SGT Medical College and Hospital, Budhera, Gurgaon, Haryana from January, 2015 to July, 2016. 3940 patients were screened for thyroid function. Thyroid function was assessed by quantitative estimation of T3 (Triiodothyronine), T4 (Thyroxine) and TSH (Thyroid Stimulating Hormone) in serum by chemiluminscent immuno assay. Results: The prevalence of thyroid disorder was found to be 25.17% (992) in the study population. 74.82% (2948) patients were euthyroid. Among the thyroid dysfunction patients 16.85% (665) belonged to hypothyroidism group (11.70% primary, 3.20% sub clinical and 3.24% clinically euthyroid) and 8.29% (327) to hyperthyroidism group (2.66% primary, 0.15% T3 thyrotoxicosis, 0.58% sub clinical and 4.89% central) Conclusion: The study findings call for a review of current practices in the management of thyroid disorders because of high prevalence of thyroid disorder in the reproductive age group (21-40). Thyroid disorders must be actively screened and monitored and to be effectively treated in diagnosed patients.
