Need for testing glucose tolerance in the early weeks of pregnancy.

AIMS: This observational study aims to determine the frequency of occurrence of glucose intolerance in the early weeks of pregnancy. MATERIALS AND METHODS: New World Health Organization 2013 guidelines recommends "A Single Step Procedure" (SSP) as an option for diagnosing gestational diabetes mellitus (GDM). Pregnant women attending 131 prenatal clinics across India for the first time underwent SSP consisting of administration of 75 goral glucose irrespective of the last meal timing and to diagnose GDM with 2 h plasma glucose (PG) value ≥7.8 mmol/L (7.8 mmol/L). RESULTS: In a cohort of n = 11,785, the number of pregnant women who underwent the test in first, second, and third trimesters were 4300, 4632, and 2853, respectively. Documented blood glucose values were available for 9282 pregnant women and in them, diagnosis of GDM was made in 740 (8%). Among them, 233 (31.5%), 320 (43.2%), and 187 (25.3%) were in the first, second and third trimesters, respectively. Positive family history of diabetes (43%) and history of fetal loss in previous pregnancy (27%) was more common in women diagnosed with GDM in the first trimester compared to GDM diagnosed in the second or third trimester. CONCLUSION: Manifestation of GDM in the early weeks of gestation is quite common.

Gestational diabetes: the public health relevance and approach.

The prevalence of diabetes is increasing globally and the causes attributed are the ageing population, urbanization, obesity epidemic, physical inactivity and stressful modern life. While all these factors contribute to the epidemic of DM, intra-uterine exposures and gestational programming are emerging as potential risk factors. Gestational programming is a process whereby stimuli or stresses that occur at critical or sensitive periods of foetal development, permanently change structure, physiology, and metabolism, which predispose individuals to disease in adult life. If the stimulus happens to be glucose intolerance in pregnancy, gestational diabetes mellitus (GDM) manifests. Diagnosis of GDM in a woman predisposes her and her offspring for increased risk of developing glucose intolerance and obesity in the future. GDM may play a crucial role in the increasing prevalence of diabetes and obesity and hence has become a public health priority issue. There has to be an excellent coordination and cooperation between all the stake holders of health delivery care system. A great understanding of the importance of GDM and its consequences by the Government and public will go a long way in containing the epidemic of diabetes.
