Gestational Diabetes: Symptoms & Management
Gestational diabetes is high blood sugar that develops in pregnancy. It often has no obvious symptoms, which is why screening matters. With good management, most people go on to have healthy babies.
What it is and who is at risk
During pregnancy, hormones can make your body resistant to insulin, raising blood sugar. Risk is higher with a family history of diabetes, higher BMI, older age, PCOS, a previous large baby, or previous gestational diabetes. South Asian women are at increased risk.
Symptoms and screening
Most women have no symptoms. When present, they may include increased thirst, frequent urination, tiredness and blurred vision. Screening is usually done with a glucose tolerance test around 24–28 weeks (earlier if high risk).
Why it matters
Uncontrolled high sugar can lead to a large baby, birth complications, low newborn blood sugar, and higher chances of pre-eclampsia. It also raises the future risk of type 2 diabetes for mother and child — but good control greatly reduces these risks.
Managing it
- Balanced diet — controlled portions, whole grains, plenty of vegetables, lean protein; limit sugary foods and refined carbs.
- Regular activity — a walk after meals helps lower blood sugar.
- Monitor blood glucose as advised.
- Some need medication or insulin if diet and exercise are not enough.
- Attend extra check-ups and scans to monitor growth.
Frequently asked questions
Will gestational diabetes go away after birth?
It usually resolves after delivery, but you will be checked afterward and have a higher lifelong risk of type 2 diabetes, so healthy habits matter.
Can I prevent it?
You can lower your risk with a healthy weight, balanced diet and activity, but it can still occur due to hormones and genetics.
Do I have to take insulin?
Many manage with diet and exercise alone. Insulin or medication is added only if blood sugar stays high, and it is safe in pregnancy.
