Alarming Rise in Gestational Diabetes Cases in Lucknow
Gestational Diabetes Mellitus (GDM), a condition characterized by high blood sugar levels developing during pregnancy, is witnessing a concerning increase in Lucknow. This upward trend reflects a steady rise linked directly to changing lifestyles and the emergence of early metabolic disorders among women of childbearing age.
Staggering Statistics from King George's Medical University
Medical professionals at King George's Medical University (KGMU) have revealed that approximately 33% of pregnant women are now either diagnosed with GDM or fall into the pre-GDM category. This translates to nearly one in every three women experiencing abnormal blood sugar levels during their pregnancy.
"On a daily basis, we diagnose about 50 women with GDM or pre-GDM out of the 150–180 women we screen," stated a faculty member from the obstetrics and gynaecology department. This current figure represents a substantial escalation compared to earlier estimates. Data from the Ministry of Health and Family Welfare in 2018 suggested that only 10–14% of pregnant women in Uttar Pradesh were affected by this condition.
Underlying Causes and National Parallels
Healthcare experts attribute this dramatic rise to several interconnected factors. These include delayed pregnancies, increasing rates of obesity, predominantly sedentary lifestyles, consumption of unhealthy diets, and a growing prevalence of insulin resistance, even among younger women. This troubling pattern in Lucknow mirrors national findings.
The ICMR-INDIAB study reported that the overall prevalence of GDM across India stands at 22.4%. This means nearly one in four pregnant women develops high blood sugar during pregnancy without any prior history of diabetes. The study further highlighted that GDM is no longer a condition confined to urban populations. Prevalence rates were found to be 24.2% in urban areas and 21.6% in rural areas, indicating a widespread health challenge.
Early Onset and Biological Mechanisms
A particularly key concern is the early onset of the condition. Research indicates that around 19.2% of women were diagnosed before 20 weeks of pregnancy, while 23.4% developed GDM after 20 weeks. This suggests that a significant number of women are entering pregnancy with pre-existing metabolic risk factors.
Explaining the biological process, Prof Smriti Agrawal from KGMU detailed that blood sugar levels are typically normal in early pregnancy. As pregnancy progresses, hormones naturally reduce the effectiveness of insulin, which is responsible for moving sugar from the bloodstream into the cells. "Some insulin resistance is normal and actually helps the baby receive adequate nutrition. However, in some women, this resistance becomes excessive and leads to the development of gestational diabetes," she clarified.
Prof Anjoo Agrawal, head of obstetrics and gynaecology at KGMU, added that specific pregnancy hormones such as hCG and progesterone further intensify this insulin resistance, compounding the issue.
Potential Complications and Management
Dr Malvika Mishra from RMLIMS outlined the potential risks associated with uncontrolled GDM. These may result in a larger baby size (macrosomia), low blood sugar in newborns (hypoglycemia), temporary breathing problems, jaundice, and difficult deliveries due to the baby's increased size.
However, she offered a crucial note of hope, emphasising that most of these complications can be effectively prevented with timely diagnosis and proper management. This underscores the importance of regular screening and adherence to medical guidance for pregnant women.
