what happens if you have gestational diabetes

If you have gestational diabetes, it means your blood sugar levels are higher than normal during pregnancy, and this can affect both you and your baby in the short and long term—but with good treatment, most people go on to have healthy pregnancies and babies.

What gestational diabetes actually is

Gestational diabetes (GDM) is a type of diabetes that first appears during pregnancy. Your body cannot make or use insulin effectively enough to keep blood sugar in the normal range, so glucose builds up in your blood.

This usually starts in the second half of pregnancy and is often picked up on routine screening (glucose challenge/tolerance tests). Many people feel completely fine and only find out from blood tests.

What happens to you during pregnancy

If blood sugar is not well controlled, you have a higher chance of certain pregnancy complications:

• Higher risk of high blood pressure and preeclampsia (a serious condition with high blood pressure and organ stress).
• Increased chance of needing an induced labour.
• Higher likelihood of needing a caesarean section.
• More physical strain in late pregnancy because of carrying a larger baby.

When gestational diabetes is well controlled with diet, exercise and sometimes medication, many of these risks are much lower and many pregnancies proceed smoothly.

What happens to your baby

High blood sugar in you means extra sugar reaches the baby, and the baby’s pancreas makes extra insulin to deal with it. This can lead to:

• Baby growing larger than average (macrosomia), which can make labour more difficult and increase the chance of shoulder injury during birth.

• Low blood sugar (neonatal hypoglycaemia) in the baby right after birth because they are used to high sugar levels and high insulin in the womb.

• Higher chance of jaundice (yellowing of the skin and eyes) after birth.

• Increased risk of breathing problems at birth, especially if baby comes early.

• Slightly higher risk of being born early or, rarely, stillborn if blood sugars are very poorly controlled.

Most babies of parents with gestational diabetes are healthy, especially when blood sugars are kept in target and pregnancy is closely monitored.

Long‑term effects on you

Having gestational diabetes is a warning sign about your future health, even if your blood sugar returns to normal after delivery.

• Strongly increased risk of developing type 2 diabetes later in life (about 7 times higher than if you did not have GDM).

• Higher chance of getting gestational diabetes again in future pregnancies.

• Increased risk of cardiovascular disease (heart and blood vessel problems) in the years after pregnancy.

Because of this, you’re usually advised to have a diabetes test about 6–12 weeks after birth and then regular checks every 1–3 years.

Long‑term effects on your child

Children born after a pregnancy with gestational diabetes have a higher risk of metabolic issues later on, especially if blood sugar was not well controlled.

• Higher risk of overweight or obesity in childhood and adulthood.

• Increased chance of impaired glucose tolerance or type 2 diabetes later in life.

• Slightly higher risk of long‑term endocrine problems (such as obesity or diabetes) compared with children not exposed to GDM in pregnancy.

The good news: a healthy family lifestyle (balanced diet, physical activity, limiting sugary drinks) can significantly reduce those risks for your child.

What treatment and monitoring look like

Once you are diagnosed, your pregnancy becomes more closely monitored, but the aim is still a normal, healthy birth.

Typical steps include:

• Nutrition changes: A tailored eating plan that spreads carbohydrates through the day, prioritizes high‑fibre, lower‑GI foods and adequate protein.

• Physical activity: Regular, pregnancy‑safe exercise (like walking or swimming) to help your body use insulin better.

• Blood sugar checks: Finger‑prick tests several times a day to keep glucose within target ranges.

• Medication if needed: If diet and exercise are not enough, insulin or sometimes tablets may be added to keep numbers safe.

• Extra scans and appointments: To track baby’s growth and plan timing and mode of birth if baby is large or complications arise.

With good management, your risk of serious complications drops dramatically.

What happens after birth

In many cases, gestational diabetes resolves soon after the placenta is delivered, because the pregnancy hormones that interfere with insulin drop quickly.

After delivery:

• Your blood sugar is usually checked to confirm it has returned to normal.

• Baby may be monitored for low blood sugar and jaundice in the first hours or days.

• You’ll be invited back for a follow‑up glucose test (usually an oral glucose tolerance test) to make sure ongoing diabetes has not developed.

Even if everything returns to normal, you’re considered higher risk for type 2 diabetes, so ongoing lifestyle care and periodic testing are important.

Forum‑style concerns people often share

On pregnancy and parenting forums, people with gestational diabetes often talk about:

“I’m terrified I’ve already hurt my baby because I was diagnosed late.”

“I feel guilty every time I eat anything with carbs.”

“What if it doesn’t go away after birth and I’m just…diabetic now?”

Common themes you’ll see in those discussions:

• Many people feel intense guilt, but GDM is largely driven by hormones and genetics, not personal failure.
• It’s very common to worry about stillbirth or long‑term damage when you read lists of complications.
• A lot of posters share that their babies were healthy and their diabetes resolved with proper management and support.

What you can do right now

If you have (or think you might have) gestational diabetes, these steps usually help:

1. Get tested and follow up
   • Attend screening tests recommended in mid‑pregnancy.
   • If already diagnosed, keep all prenatal and diabetes appointments.
2. Follow your care plan
   • Work with your midwife/OB and diabetes team on diet, activity and medications.
   • Ask what target glucose numbers you should aim for.
3. Support your long‑term health
   • After birth, go to your follow‑up glucose test.
   • Maintain a healthy weight, stay active, and eat a balanced diet to lower future diabetes and heart‑disease risk.
4. Support your child’s future health
   • As they grow, encourage active play, limit sugary drinks, and offer varied, balanced meals.
