Prevalence of thyroid disorders in Gestational Diabetes mellitus (GDM) : A tertiary centre study

Gestational diabetes mellitus (GDM) and especially pregestational diabetes mellitus, are known as risk factors for pregnancy complications, effecting both the mother and the fetus. The aim of this study was to determine the prevalence of the thyroid disorders in pregnant women with gestation diabetes mellitus (GDM). A study on the prevalence and possible risk factors associated with gestational diabetes was undertaken on 100 mothers between the age group of 20 and 35 years; among pregnant women recruited from Gynecology and Obstrectics outpatient of S.M.S Medical College, Jaipur, Rajasthan from January 2016 to January 2017. In this study 100 women were divided in two groups, Group I (n=50) were control group (non gestational diabetic) and Group II (n=50) was study group (gestational diabetic). In present study maximum subjects 35 (70%) seen in control group and 31 (62%) in study group in 25-32 years of age group. The prevalence of thyroid disorder (hypothyroidism) in gestational diabetes females was 12%. In comparisons to control group, women with gestational diabetes and hypothyroidism were statistically significant (p=0.229*). Thyroid dysfunction is prevalent in women with GDM so, thyroid function should be evaluated in these patients during pregnancy. Moreover, the lack of information regarding how tight the thyroid function and glucose concentrations were under control and the BMI of the patients may also serve as possible confounding factors.
