Prevention of diabetes before birth offers hope for healthy future, PgII

Key Highlights:

• India faces a significant public health challenge with 101 million people living with diabetes and 136 million in a prediabetic state.
• Gestational Diabetes Mellitus (GDM) affects nearly one in five pregnancies globally, posing long-term health risks for both mothers and children.
• Early screening and intervention for GDM in the first trimester, ideally by the 8th week of pregnancy, is crucial to prevent foetal programming.
• A simple two-hour postprandial blood glucose (PPBG) test at eight weeks can identify Early Gestational Glucose Intolerance (EGGI), allowing for timely intervention.

Detailed Insights:

• Foetal programming explains how high maternal blood sugar levels can lead to increased insulin production in the foetus, predisposing the child to metabolic disorders.
• Screening for GDM typically occurs in the second trimester, which may be too late to prevent foetal programming and its long-term metabolic consequences.
• Identifying elevated postprandial glucose in the first trimester can reduce the progression to overt GDM, as supported by recent multicentre work from 2022-2024.
• Interventions such as medical nutrition therapy, lifestyle modification, and low-dose metformin can help normalize maternal glucose levels before the 10th week of gestation.
• A national policy mandating universal early pregnancy glucose screening, along with preconception counselling and early antenatal registration, could transform diabetes prevention.
• By interrupting intergenerational metabolic transmission, India could reduce future diabetes prevalence, cardiovascular disease burden, and associated healthcare expenditure.

Key Concepts Involved:

• Gestational Diabetes Mellitus (GDM): Glucose intolerance first detected during pregnancy.
• Foetal Programming: Adverse metabolic conditions in utero can permanently alter a child’s physiology.
• Postprandial Blood Glucose (PPBG): Blood sugar level measured two hours after a meal.
