Delivering a Baby When You Have Type 1 Diabetes
Welcoming a baby into the world when you have T1D is much like any birth, with some extra attention to your blood sugar along the way.
What to Expect During a Vaginal Birth
Your birth experience will likely feel similar in many ways to that of other expectant mothers without type 1 diabetes (T1D). One key difference, though, is that your blood sugar will be monitored closely throughout labor and delivery. If you’re not using a continuous glucose monitor (CGM), this may involve more frequent finger checks, but this extra attention helps keep both you and your baby safe.
Keeping a close eye on your blood sugar supports you during labor, when physical and emotional stress can sometimes cause levels to rise or fall. If your levels do go out of range, your care team will be right there to help, making small adjustments with insulin or glucose as needed.
If your birth plan changes and a C-section is needed, things like eating or drinking can become a bit more complex. That’s another reason your team will keep monitoring your blood sugar closely—to help ensure everything goes as smoothly as possible.
As your labor progresses and your cervix dilates, you’ll be guided on when to push. Around the time your baby arrives, it’s common for insulin needs to drop quickly, sometimes even returning to pre-pregnancy levels soon after birth. Every experience is different, so it’s a good idea to talk with your healthcare provider about how to adjust your insulin during this time.
Planning for a Hospital Stay with T1D
A hospital stay with type 1 diabetes can come with a few added considerations, especially when it comes to monitoring blood sugar and adjusting insulin. Being informed about what to expect, staying involved in your diabetes management, and planning ahead when possible can help you feel more confident and comfortable throughout your stay.
What to Expect During a C- Section Birth
While a C-section can sometimes be an unexpected change in a birth plan, it’s also something women with T1D may choose to plan for ahead of time. There are a few different reasons this might be recommended, including your baby’s size or certain health considerations like retinopathy or kidney concerns. In some cases, your care team may also suggest an earlier delivery, especially if you’ve had a previous C-section or if there are specific maternal or fetal health needs.
If your C-section is scheduled, you’ll have time to talk through the details with your healthcare team in advance. Every team approaches diabetes management a little differently—some are comfortable having you and your support person take the lead, while others prefer to manage it closely throughout the procedure. If you use an insulin pump, CGM, or other device, you may be asked to remove it beforehand, but this is something you can decide together with your care team.
To prepare for surgery, you’ll typically receive a spinal block (sometimes called an epidural) to numb the lower half of your body. You’ll also likely have two IV lines: one for fluids and one for insulin if your pump isn’t in use. Often, insulin and glucose are given together through the IV, and your care team can adjust the balance based on your blood sugar levels. If your levels begin to dip or rise, they’ll make quick adjustments to help keep things on track.
The procedure itself usually takes about an hour, though every experience is a little different.
Recovery after a C-section can feel different from recovering after a vaginal birth. You may have a urinary catheter for a short time, along with stitches or staples as your body heals. During this period, keeping an eye on your blood sugar remains especially important, as shifting hormones and the stress of surgery can affect your insulin needs. Staying as close to your target range as possible can also support healing.
Some women notice things like shaking or nausea during or after a C-section. It can be helpful to talk through a plan with your care team ahead of time so you feel prepared, especially in case your blood sugar drops unexpectedly.

After Delivery
Immediately after delivery, your baby will likely be examined using the Apgar test—this looks for any immediate concerns regarding your baby’s breathing, heart rate, muscle tone, reflexes, and color. As a woman with T1D, your baby’s blood sugar will also be checked. It is common for babies of mothers with T1D to be born with low blood sugar. Your baby’s healthcare team will treat low blood sugar with glucose.
While diabetes management is just as important now that your baby is born, you might talk to your healthcare team about adjusting your time-in-range target at this time while you heal and adjust to life as a new mother!
