To Study Incidence of Subclinical Hypothyroidism in Pregnancy and Effectiveness of Treating It

This study was hospital based, time bound prospective analytical study. In this study we enrolled 2000 antenatal patients and screened them for hypothyroidism. All patients were followed up till delivery. out of 2000 pregnant women included in the study, 160 women had subclinical hypothyroidism with an incidence of 8 %. subclinical hypothyroidism was most commonly observed in the age group of more than 30 years (31.81 %) followed by 21 to 25 years (6.12 %), less than 20 years (5 %) and 26 to 30 years (4.5 %) of the patients The mean age of patients was 26.85 3.04 years. There was a positive correlation between subclinical hypothyroidism and higher maternal age (p=0.018). The incidence of Pregnancy induced hypertension, prematurity and recurrent abortions was also higher in patients suffering from subclinical hypothyroidism. Subclinical hypothyroidism is an easily treatable maternal condition which reduces the pregnancy associated maternal and fetal morbity. Hence guidelines should be set for universal screening of hypothyroidism in pregnancy.
