Background: Thyroid dysfunction is the most common endocrinological disorder in pregnancy, only second to diabetes. The present study was conducted to assess the prevalence of hypothyroidism in pregnancy. Materials & Methods: The study was conducted among 400 pregnant women over a period of one year. After a detailed history and thorough examination, screening for thyroid disorder was done. The data were analyzed using the IBM SPSS. P-value less than 0.05 (p < 0.05) was considered statistically significant. Results: In our study, 42 patients out of 400 pregnant women have a thyroid disorder. The prevalence of thyroid dysfunction in our study was 10.5% in which the prevalence of hypothyroidism and hyperthyroidism was 6.5% and 3.5%, respectively. Subclinical hypothyroidism and overt hypothyroidism were observed in 18 and 8 patients, respectively, while subclinical and overt hyperthyroidism was observed in 10 and 4 women, respectively. Patients with subclinical hypothyroidism, overt hypothyroidism, overt hyperthyroidism were more common in the age group of 30-35 years while patients with subclinical hyperthyroidism were more common in the age group 26-30 years and significant distribution was observed between thyroid disorders with age. Conclusion: The present study concluded that thyroid dysfunction was 10.5% in this study. Hypothyroidism was more common than hyperthyroidism and subclinical thyroid disorders were more common than overt thyroid disorders in pregnancy.
