There is a wide geographic variation in the prevalence of hypothyroidism. It varies from 2.5% in the west to 11% in India. Prevalence of hypothyroidism was found to be more in Asian countries compared with the west. Therefore the present study was carried out to study the prevalence of thyroid disorders in pregnancy in our hospital. To study the prevalence and fetal and maternal outcome in thyroid disorders complicating pregnancy in a teaching hospital.

Results: In our study, the prevalence of thyroid disorders was 10.6%. The incidence of Subclinical hypothyroidism was 9.1% and Overt Hypothyroidism was 1.1%, Sub-clinical hyperthyroidism was 0.3% and Overt Hyperthyroidism was 0.1%. The incidence of Pre-eclampsia was 15.09%, Anaemia 16.04%, Pre- term delivery 9.43%, LBW 11.32%, IUFD 2.83% and Caesarean deliveries 15.09% in 106 pregnant women with thyroid disorders.
