Pregnancy With a Stoma UK: What to Expect Before, During and After Delivery
If you have a stoma and you're pregnant, thinking about becoming pregnant, or just quietly wondering whether it's even possible — you're not alone. Most of the worry around this topic comes from not knowing what actually changes, and not seeing it talked about openly. Here's what genuinely happens to your body, your stoma, and your routine at each stage.
The short answer
Yes — you can have a healthy pregnancy and a safe delivery with a stoma. Your stoma will change along the way, and your appliance sizes will too. Plan for regular re-measuring, softer adjustable support, and early coordination between your obstetric team and your NHS stoma care nurse.

Can you get pregnant with a colostomy, ileostomy or urostomy?

No — a stoma does not affect fertility on its own. Many stoma patients conceive naturally and carry full-term, healthy pregnancies, and the stoma itself plays no role in whether you can become pregnant.
If your stoma came from Crohn's, colitis, or cancer
If your stoma was formed because of Crohn's disease, ulcerative colitis, or another underlying condition, that condition — not the stoma — is what your care team will monitor most closely. If you're planning a pregnancy, involve both your stoma care nurse and your gastroenterologist or urologist early, ideally through your GP referral pathway before you start trying.
02 — Your stoma
How your stoma changes as your bump grows
Your abdomen changes shape dramatically over nine months, and your stoma changes along with it. This is normal, and it's the part that surprises people most.
What you'll notice
- The stoma itself may protrude more or less as the surrounding skin stretches and the abdominal wall shifts.
- Your usual flange size will likely stop fitting at some point, often around the second trimester.
- The stoma's position relative to your waistline moves as your bump rises, changing how a pouch sits under clothing.
- Skin around the stoma stretches, which can make the peristomal area more sensitive — extra gentle skin care matters more than usual.
Trimester by trimester
Why re-measuring matters
Your appliance fit is your best early-warning system — a flange that fit perfectly last month can quietly start leaking this month. Your NHS stoma nurse can re-measure you at any point; you don't need to wait for a scheduled appointment.
03 — Comfort
Staying comfortable as your bump grows
The biggest everyday challenge is usually comfort, not medical risk. A few deliberate swaps make the difference.
Support that grows with you
- Switch to an adjustable, stretch-friendly stoma belt rather than a fixed-size one — you need support that grows with you week to week, not one that digs in by month six.
- Move the belt lower or higher as needed to sit comfortably around the bump rather than across it.
What to wear
- Choose soft, high-waisted stoma underwear with stretch panels instead of firm, structured styles that were comfortable pre-pregnancy but aren't anymore.
Daily routine adjustments
- Empty your pouch more frequently — pressure from a growing uterus on your bladder and bowel often means more frequent, and sometimes more urgent, output.
Comfort that adjusts with you
The SIIL Stoma Belt is soft, breathable, and designed to move with your body as it changes.
04 — Delivery
Vaginal delivery or C-section: which is safer with a stoma?
Can you deliver vaginally with a stoma?
This is the question most people are actually afraid to ask. Having a stoma does not automatically mean you need a caesarean — vaginal delivery is possible and common for stoma patients, and the right choice depends on your specific anatomy, your surgical history, and your obstetric team's assessment, not on the stoma alone.
When a planned caesarean makes sense
- A parastomal hernia or significant scar tissue near the birth canal
- A stoma sited very close to the pelvic area where vaginal delivery could put unusual strain on it
- A history of complex pelvic surgery alongside the stoma
Talk to your team early
Your obstetric team and your stoma or colorectal surgical team should coordinate directly well before your due date — raise this explicitly at your booking appointment, not for the first time on the delivery ward.
05 — Postpartum
What changes after delivery
Your stoma in the weeks after birth
Postpartum, your abdomen shrinks back over weeks, not overnight, and your stoma will keep shifting during that time too. Expect to re-measure your flange again in the weeks after birth — don't assume your pregnancy-size appliance, or your original pre-pregnancy size, is automatically right again. A soft, adjustable support belt is genuinely useful here as your abdominal muscles recover, in the same way it was during pregnancy.

Questions worth asking your care team
Save these for your next appointment
- Should I plan to re-measure my stoma on a set schedule, or only when something feels wrong?
- Given my surgical history, is a vaginal delivery realistic, or should we plan for a caesarean?
- Are there specific signs during pregnancy (pain, unusual swelling, prolapse) that mean I should contact my stoma nurse or the maternity unit immediately?
- Will my underlying condition (Crohn's, ulcerative colitis, cancer history) need extra monitoring during pregnancy?
Pregnancy with a stoma is not a medical footnote — it's a normal, well-documented path that thousands of stoma patients across the UK have walked before you. The changes are real and worth planning for, but they are manageable, and you deserve an NHS care team and a wardrobe that keeps up with you at every stage.
