Iqra Riyaz, Ulfat Shah

Abstract: Subclinical hypothyroidism is the most commonly encountered endocrinological disorder in pregnancy and it affects normal fetal growth and metabolism. Our study was conducted over a period of one year in 150 singleton pregnancies with gestational age >28 weeks and thyroid function tests were done in them and incidence of subclinical hypothyroidism was noted and its effects on perinatal outcome were noted and compared with euthyroid patients. It was concluded that incidence of intrauterine deaths, fetal prematurity, low birth weight, NICU admissions and perinatal mortality was more in subclinical hypothyroid patients as compared to those with euthyroidism.
