Pregnancy is an important period in life when mothers need to pay extra attention to their health because every change in the body not only affects the mother herself but also the little one in the womb. One condition that many mothers may not know they are at risk for is “Gestational Diabetes Mellitus” (GDM), a condition where blood sugar levels rise during pregnancy even if the mother has never had diabetes before
If this condition is not properly managed, it can affect the health of both mother and baby. However, if detected early and properly advised by a doctor, it can be controlled and a safe delivery can be achieved. This article will help mothers understand what gestational diabetes is, its causes, and how to take care of themselves to confidently go through pregnancy.
What is Gestational Diabetes?
“Gestational Diabetes Mellitus (GDM)” is a condition where a pregnant woman has higher than normal blood sugar levels during pregnancy, even though she has never had diabetes before.
This condition usually occurs between 24–28 weeks of pregnancy because the mother’s body produces a large amount of hormones from the placenta, which may interfere with the action of “insulin” that controls blood sugar levels, causing blood sugar to rise and resulting in diabetes.
Although this condition usually disappears after delivery, if not properly managed, it may increase the risk of difficult labor or affect the child’s long-term health.
Causes and Risk Factors of Gestational Diabetes
This condition is not caused by “eating too much sugar” alone but results from several combined factors, including
- Hormones from the placenta cause the body to become more resistant to insulin
- Being overweight before pregnancy or obese
- Age over 35 years
- Family history of diabetes
- Previous gestational diabetes
- Previous delivery of a large baby (over 4 kilograms)
Mothers with these risk factors should undergo screening from the beginning of prenatal care to plan appropriate health management early on.
Symptoms of Gestational Diabetes
Most mothers with this condition do not show clear symptoms. Doctors usually detect it through blood tests during prenatal visits, but some may experience symptoms such as
- Excessive thirst
- Frequent urination
- Easily tired or fatigued
- Abnormal weight gain
If you suspect you are at risk, you should see an obstetrician promptly for a blood sugar test (OGTT), which involves drinking a sugar solution and having blood drawn to check blood sugar levels after 1–2 hours
Effects of Gestational Diabetes
Effects on the mother
- Risk of pre-eclampsia
- Risk of preterm delivery or delivery by C-section
- Increased risk of developing type 2 diabetes after delivery in the future
Effects on the baby
- Larger than normal baby (Macrosomia), making delivery difficult
- May have hypoglycemia after birth
- Risk of respiratory distress or obesity and diabetes in the future
Guidelines for Managing and Preventing Gestational Diabetes
- Control diet
- Eat a balanced diet from all 5 food groups but limit simple carbohydrates such as sweets, sugary drinks, and soda
- Choose complex carbohydrates such as brown rice, whole grains, vegetables, and less sweet fruits
- Divide meals into 5–6 small portions per day to maintain stable blood sugar levels
- Exercise appropriately
- Light walking, swimming, or prenatal yoga for 20–30 minutes per session
- Consult a doctor before starting any exercise
- Monitor blood sugar levels
- Check blood sugar as advised by your doctor
- If diet and exercise are not enough to control blood sugar, insulin injections may be required under medical supervision
- Postpartum health monitoring
- Check blood sugar levels again 6–12 weeks after delivery
- Regular health check-ups are recommended to reduce the risk of developing type 2 diabetes
Frequently Asked Questions
Q: Can gestational diabetes be cured?
A: It usually resolves after delivery, but follow-up with a doctor is important because these mothers have a high risk of developing type 2 diabetes in the future.
Q: If I have gestational diabetes, do I have to deliver by C-section?
A: Not necessarily. If blood sugar is well controlled and the baby is not too large, normal delivery is possible.
Q: Will the baby be affected?
A: If the mother controls blood sugar well, the effects on the baby will be greatly reduced, increasing the chances of a safe and healthy delivery.
Gestational diabetes is not a distant issue for pregnant mothers and can be managed if recognized early and health is regularly monitored. Proper nutrition planning, appropriate exercise, and regular follow-up with a doctor will help keep both mother and baby safe throughout pregnancy.
