BACKGROUND Thyroid disorders are the second most common endocrinological disorders seen in pregnant women. Thyroid hormone plays a crucial role in pregnancy both in the development of a healthy baby and in maintaining the health of the mother. Several studies have shown a rising prevalence of thyroid disease in India and in South Asian countries. The diagnosis of thyroid disease in pregnancy is difficult as many of the signs and symptoms of thyroid disease are also common to pregnancy. The aim of the study is to determine the prevalence of thyroid disease in pregnant women. MATERIALS AND METHODS This is a hospital-based cross-sectional study. 333 antenatal women were screened in their first visit to the antenatal clinic by serum TSH, fT3, fT4. Statistical analysis of the results was done. RESULTS 283 women out of 333 antenatal women screened were found to be euthyroid. 50 women were detected to be having thyroid disorder. 45 women had subclinical hypothyroidism, one woman had overt hypothyroidism and four women had subclinical hyperthyroidism. 4 women had hypothyroidism prior to pregnancy. The overall prevalence of thyroid disorders in pregnancy in our study was found to be 16.21%. CONCLUSION The prevalence was found to be high in our study and in several studies from India and in its neighbouring countries. This is probably due to iodine deficiency being prevalent in several areas in our country. The prevalence of subclinical hypothyroidism is high. This all the more stresses the need for universal screening of pregnant women for thyroid disease in our country.
