Introduction: Women with known thyroid disease will need to have their treatment adjusted and more frequently monitored during pregnancy.
Aims: To determine the proportion of thyroid dysfunction in pregnancy and determine the different types of thyroid dysfunction during pregnancy.
Materials and Methods: The present study is an Observational Study done on 300 pregnant women with gestational age ≤14 weeks. It was done to detect the prevalence of thyroid dysfunction. TSH levels were evaluated in the subjects and if it was elevated, ft3 and ft4 was done. TPO antibodies was done in this with raised TSH, family history of thyroid disease and those with autoimmune disorders.
Results: The prevalence of thyroid disorders in the present study was 25%. The prevalence of hypothyroidism in the present study was 21.7%. The prevalence of subclinical hypothyroidism and overt hypothyroidism in our study was 16.7% and 5%. The prevalence of total hyperthyroidism was 3.3%. The prevalence of subclinical and overt hyperthyroidism in our study was 2.3% & 1% respectively. Among the hypothyroid, 22% of subclinical and 53.3% of overt hypothyroid were positive for TPO antibodies.
Conclusions: Serum TSH for all pregnant women will help in early detection, and by giving appropriate treatment it thus prevents maternal and fetal complications of thyroid disorders.
