Key tips on diabetes after giving birth

Updated 25 Oct 2026

Gestational diabetes can harm the health of both mum and baby. It is usually detected from the 4th month of pregnancy and usually resolves about 06 weeks after the birth.
As well as paying special attention to diet and exercise during pregnancy, keep the following points in mind to control your blood sugar well after the birth. Content advised on and reviewed by Dr Lê Phạm Anh Vy (Specialist Level I), Head of Nutrition, American International Hospital (AIH).
Keep an eye on your weight.
Believing they must eat a lot to make milk for their baby, mums often eat too much rich, nourishing food after giving birth. This is what causes uncontrolled weight gain. When your weight changes too quickly, it can affect your metabolism and increase the risk of chronic diabetes.


Choose low-GI foods.
Choosing foods with a low glycaemic index (GI) helps you control your blood sugar intake better. A diet that limits high-GI foods such as refined grains, cakes and sweets or sweet fruits can help reduce the risk of complications related to type 2 diabetes, keep you feeling full for longer and maintain your target weight.
Split your daily meals into smaller ones.
Splitting your daily food into three main meals and 2-3 snacks helps you avoid sudden blood sugar spikes after meals. Also, only eat starchy foods (rice, potatoes, corn) at main meals to avoid taking in too much sugar.
Do gentle exercise (walking, yoga) for at least 30 minutes in a row every day.
Gentle exercise and activity will help you get better results alongside a healthy diet. Physical activity helps your body's metabolism work better and helps you become firmer and healthier.


Monitor your blood sugar correctly
Monitoring your blood sugar correctly and regularly lets you act and adjust your diet in time to control your blood sugar better.

As well as the points above, don't forget your postpartum diabetes follow-up check at a healthcare facility to keep you and your baby healthy after the birth.
