Background: Pregnancy has a profound physiological impact on the thyroid gland and thyroid function. The present study was conducted to assess the prevalence of hypothyroidism in pregnancy.Material & methods: The study was conducted among 280 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 version 23 (Armonk, NY). P-value less than 0.05 (p < 0.05) was considered statistically significant.Result: In our study, 60 patients out of 280 pregnant women have a thyroid disorder. The prevalence of thyroid dysfunction in our study was 21.42% in which the prevalence of hypothyroidism and hyperthyroidism was 15% and 6.4%, 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 <25years and significant distribution was observed between thyroid disorders with age.Conclusion: The study concluded that thyroid dysfunction was prevalent in 21.42% and the prevalence of hypothyroidism and hyperthyroidism was 15% and 3.5%, respectively. Hypothyroidism was more common than hyperthyroidism and subclinical thyroid disorders were more common than overt thyroid disorders in pregnancy.
