What Exactly Is Gestational Diabetes?
Let’s clear up the confusion first. Gestational diabetes mellitus (GDM) is a condition in which blood sugar levels rise during pregnancy, even if the woman never had diabetes before. It usually shows up around the 24th to 28th week — the time when the placenta starts producing hormones that can interfere with insulin (the hormone that keeps blood sugar under control). Here’s what happens behind the scenes:- During pregnancy, the placenta releases hormones that make the mother’s body slightly insulin resistant — to ensure enough glucose reaches the growing baby.
- But sometimes, this resistance becomes too strong. The mother’s pancreas can’t keep up, and blood sugar levels start to climb.
How Common Is It Really?
Far more common than most people realize. In India, according to the Indian Council of Medical Research (ICMR, 2023), nearly 1 in 6 pregnant women develops gestational diabetes. That’s around 5 million women every year. And here’s the alarming part: nearly 50% of them don’t even know it. Why? Because many cases show no obvious symptoms — no dizziness, no fainting, no visible “sugar rush.” It’s invisible, unless tested.“But It Goes Away After Pregnancy, Right?”
Technically yes — gestational diabetes often disappears after delivery. But the story doesn’t end there. Think of it like an alarm clock. The body is trying to wake you up early to prevent future disasters. If ignored, here’s what usually happens:- Mothers with a history of GDM are 10 times more likely to develop Type 2 diabetes later in life.
- Babies born to mothers with GDM have a 4–6 times higher risk of obesity, insulin resistance, and early-onset heart disease.
- These babies are also more prone to developing metabolic disorders before they even turn 20.
