If you’ve been told you might need insulin or medication to manage your gestational diabetes (GD), you’re not alone — and you’re certainly not a failure.
For many expecting moms, hearing the words “we’ll have to start medication” can trigger an avalanche of guilt, shame, or worry. You might wonder:
Did I do something wrong?
Could I have tried harder with food or exercise?
Am I already failing my baby?
The truth? Needing medication for gestational diabetes is not a personal failure. It’s often just a sign of how pregnancy hormones work — and how your body needs a little extra help to keep you and your baby healthy.
Let’s break it down, so you can hopefully breathe a little easier.
Gestational diabetes is largely driven by hormones from the placenta that make it harder for your body to use insulin. Some people’s bodies can compensate, others can’t. It’s not about willpower, eating “perfectly,” or being disciplined enough.
Even with the best meal planning, balanced snacks, staying hydrated, walking after meals — your blood sugar may still run higher than target. That’s biology, not your fault.
In fact, research suggests that around 15–30% of people with gestational diabetes need insulin. It’s very common.
When your care team recommends insulin or oral meds, it’s not because you’ve done something wrong. It’s because keeping your blood sugar in range is the single best way to reduce the risks that can come with GD (like baby growing too large, complications at delivery, or blood sugar issues after birth).
Medication is simply one more tool — just like healthy eating, regular movement, or checking your glucose.
Insulin doesn’t cross the placenta, so it’s considered the gold standard when food & lifestyle changes alone aren’t enough.
Oral medications (like metformin) also have safety data for pregnancy and may be used depending on your specific situation.
Using medication is an act of protection, not defeat. It means you’re doing everything you can to keep your pregnancy as healthy as possible.
It’s completely normal to feel disappointed or anxious at first. Here are a few thoughts that might help reframe things:
It’s not a reflection of effort. Many people eat well, walk daily, and still need meds. It’s your placenta’s insulin resistance, not your failure.
Think of insulin or meds as guardrails. They’re there to keep your baby safe on this journey, not as a punishment.
It’s temporary. For most people, insulin stops after delivery, once those pregnancy hormones clear. It doesn’t mean you’ll have diabetes forever.
You’re showing up. Testing, adjusting, taking medication if needed — that’s loving, proactive parenting already.
If you’re nervous, it’s okay to bring that up. Try asking:
What type of medication do you recommend, and why?
How will we monitor and adjust doses?
What should I watch for?
Will this affect my delivery or baby’s first days?
A good care team will reassure you and keep you in the loop.
If your provider recommends medication, they’ll choose the type based on your glucose patterns, time of day when spikes happen, and your health history. Here’s a closer look at the most common options:
When it's used:
If your fasting blood sugar (the number when you wake up) is consistently high, you may need long-acting insulin. It helps manage blood sugar levels between meals and overnight.
Examples:
Insulin NPH (Humulin N, Novolin N) – often used in pregnancy due to its long safety history
Insulin Detemir (Levemir) – also approved for use in pregnancy
Insulin Glargine (Lantus) – sometimes used off-label with close monitoring
Key points:
Usually taken once or twice a day
Doesn’t peak sharply — helps maintain stable background levels
Doesn’t cross the placenta — safe for baby (Diabetes Care 2019)
When it's used:
If your post-meal blood sugars (1 or 2 hours after eating) are high despite meal changes, you might need rapid-acting insulin before meals.
Examples:
Insulin Lispro (Humalog)
Insulin Aspart (NovoLog)
Key points:
Taken right before meals to help manage the rise in blood sugar from eating
Starts working within 15–30 minutes, peaks around 1–2 hours
Flexible — dose can be adjusted based on meals and glucose trends
Doesn’t cross the placenta — safe for baby
When it's used:
Sometimes offered instead of or alongside insulin — especially when insulin resistance is more significant, or if fasting numbers are high.
Metformin helps reduce insulin resistance and lower liver glucose production.
Key points:
Taken in pill form (usually once or twice daily)
It crosses the placenta, but evidence supports short-term safety in pregnancy, though long-term outcomes are still being studied (Springer)
May cause mild GI side effects like nausea or diarrhea at first
Not suitable for everyone — depends on your blood sugar patterns and health history
Sometimes used in combination with insulin
When it's used:
Glyburide may be used if metformin isn’t effective or tolerated — though it’s now less commonly recommended due to safety concerns.
Glyburide is a sulfonylurea that stimulates the pancreas to release more insulin.
Key points:
Taken as a pill, usually once or twice a day
Crosses the placenta, more so than metformin
Associated with a slightly higher risk of low blood sugar (hypoglycemia) in newborns (BioMed Central)
Use during pregnancy is more controversial — many providers now prefer insulin or metformin first
Still sometimes used when insulin isn't an option, and with close monitoring
At the end of the day, gestational diabetes isn’t about perfection — it’s about learning what your unique body needs right now. Sometimes that’s lower-carb meals. Sometimes it’s more walking. Sometimes it’s insulin.
It all counts as taking care of your baby.
If you’re feeling weighed down by guilt or shame, please know:
Needing medication doesn’t make you a bad mom. It makes you a mom doing everything possible to keep your little one safe.
Medication isn’t failure — it’s a protective step.
Needing extra help doesn’t mean you didn’t try hard enough.
Your baby is lucky to have you, showing up and caring so much.
This is just one chapter, and you’re doing beautifully.
1. Do I need medication for gestational diabetes if I’m eating a healthy diet and exercising?
Not always. Many pregnant women can manage gestational diabetes through lifestyle changes such as dietary changes and regular exercise. However, if blood glucose levels remain high despite these efforts, your healthcare professionals may recommend medication to achieve optimal glycemic control and protect your baby’s health.
2. How do healthcare professionals decide which medication is best for me?
Your health care team will consider your blood sugar readings, results from your glucose tolerance test, your overall health conditions, and how your pregnancy progresses. Factors like insulin sensitivity, weight gain, and blood glucose patterns help determine whether insulin injections or oral medications like metformin or glyburide are the best treatment options.
3. Is insulin safe to use during pregnancy?
Yes. Insulin does not cross the placenta and is considered the gold standard for managing gestational diabetes when lifestyle changes are insufficient. It helps control blood sugar without posing risks to the baby and can be adjusted as your pregnancy progresses.
4. What is bedtime insulin for gestational diabetes?
Bedtime insulin is a long-acting insulin taken at night to help control blood sugar levels in gestational diabetes. It works by maintaining steady insulin levels overnight, preventing high fasting blood sugar and supporting a healthy pregnancy.
5. Will I need to continue medication after my baby is born?
Usually, medication for gestational diabetes is only needed during pregnancy. After birth, your blood sugar levels will be monitored, and most women find their blood glucose returns to a healthy range. However, you will have an increased risk of developing type 2 diabetes later, so regular check-ups and healthy lifestyle habits remain important.
6. How often should I check my blood sugar at home?
Your healthcare team will guide you on how often to check your blood sugar. Typically, blood sugar is checked fasting (first test in the morning) and after meals to ensure levels stay within a healthy range. Recording your blood sugar readings helps your care team adjust your treatment plan if needed.
7. Can gestational diabetes affect my baby’s health?
If not well controlled, gestational diabetes can increase risks such as high birth weight, birth complications, and neonatal hypoglycemia. Achieving glycemic control through a healthy diet, physical activity, and medication when necessary helps minimize these risks and supports a healthy pregnancy.
8. What should I do if I experience symptoms of low blood sugar?
Symptoms of low blood sugar include feeling shaky, sweaty, hungry, or dizzy. If you experience these, check your blood sugar immediately and treat it by consuming fast-acting carbohydrates like juice or glucose tablets as advised by your healthcare provider.
9. How does physical activity help manage gestational diabetes?
Regular exercise helps your body use glucose more effectively, improving insulin sensitivity and helping to keep blood glucose levels within a healthy range. Your healthcare team can recommend safe exercises tailored to your pregnancy.
10. Are there any foods I should avoid with gestational diabetes?
Limiting sugary drinks and refined carbohydrates can help control blood sugar levels. Your dietitian or healthcare professionals can help you plan a healthy diet that supports both you and your baby’s needs during pregnancy.
