Gestational Diabetes in India: What the ICMR Data Says, When to Get Tested and a Practical Plan

By Motherly Team | Reviewed by Motherly's Clinical Team | Last reviewed: 4 November 2026

How common is gestational diabetes in India?

The ICMR-INDIAB survey of 1,032 pregnant women across all states and union territories found 22.4% had gestational diabetes, with early GDM at 19.2% and late GDM at 23.4%. Regional rates were highest in Central India (32.9%) and North India (31.4%), then South India (24.2%), East (17.9%), the North-East (16.6%) and West India (16.0%). Earlier estimates are lower: a 2024 systematic review pooled 13% and stressed that screening and diagnostic criteria vary across states. Whatever the exact number, it is high enough that universal testing is the standard of care.

When should I be tested, and which test is used?

National guidance is to test at the first antenatal visit and repeat at 24 to 28 weeks if the first test is normal. Two approaches are common in India; your doctor chooses one:

Thresholds can differ slightly between hospitals, so follow your own doctor's result.

Who is at higher risk?

South Asian ancestry, a family history of diabetes, previous gestational diabetes or a large baby, PCOS (see our PCOS and pregnancy guide), age above 30 and overweight all raise risk. But the Indian STRiDE study data found early GDM was surprisingly common in women from lower-income groups despite lower BMI, which is why testing is advised for everyone.

What should an Indian gestational diabetes plate look like?

This is Motherly's practical swap framework. Your doctor or dietitian will personalise portions:

Do not skip meals or fast to "control" sugar. Missing meals can cause ketones and low sugar, and vrat fasting in pregnancy needs your doctor's advice. Our first trimester pregnancy diet plan and complete nutrition guide cover the fundamentals.

Do walks after meals really work?

For many women, a gentle 10 to 15 minute walk after meals blunts the post-meal sugar spike. Start after your biggest meal. Stop if you feel dizzy, have contractions or bleeding, and check with your doctor first if you have been advised to limit activity. In smog season, walk indoors: see our Diwali smog guide, or try prenatal yoga at home (learn more about prenatal yoga benefits).

How will I monitor my sugar, and what are the targets?

You will usually check fasting and after-meal readings with a glucometer and keep a log. Commonly used targets worldwide are fasting under 95 mg/dL, 1 hour after meals under 140 and 2 hours under 120, but your doctor sets yours. If diet and activity are not enough, your doctor may add insulin or metformin. That is not a failure, and treating high sugar protects you and your baby.

What does it mean for my baby and delivery?

Untreated high sugar can lead to a larger baby, low blood sugar after birth, preterm birth and a higher chance of caesarean delivery. Tell the hospital you had gestational diabetes so they can check your baby's sugar, and plan early skin-to-skin and frequent feeds (consult our lactation consultants). For birth-mode questions, read our epidural, normal birth or C-section guide.

After delivery, get a glucose test 6 to 12 weeks postpartum and screen regularly afterwards, because gestational diabetes raises later type 2 diabetes risk.
