Growth & Puberty
Helping your child feel comfortable about their body
How Crohn’s disease and ulcerative colitis can affect body confidence, growth, weight, puberty and eating, plus practical ways to support your child’s self-esteem and wellbeing.

Is your child becoming more aware of their body, comparing themselves with friends, or feeling uncomfortable about changes caused by IBD?
Growing up can make children and teenagers more aware of how they look and how their bodies compare with other people’s. For children with Crohn’s disease or ulcerative colitis, this can sometimes feel even more complicated.
IBD can affect growth, weight, puberty, skin, hair, scars, bloating and body shape. Some medications can also cause temporary changes in appearance.
Your child may feel different from their friends — even when there is nothing medically wrong with their body.
Helping them develop a positive and comfortable relationship with their body isn’t about making them love every part of themselves. It’s about helping them understand that their body is changing, their worth isn’t based on appearance, and they deserve to feel comfortable and supported.
💬 Start by listening
If your child says something negative about their body, it can be tempting to immediately reassure them:
“You look completely fine!”
Although this is well intentioned, it can sometimes make a child feel like their concerns haven’t been heard.
Instead, try asking:
“What makes you feel that way?”
“Have you been thinking about this for a while?”
“Is someone saying something at school?”
“Are you worried about something changing because of your IBD?”
“What would help you feel more comfortable?”
You don’t have to immediately fix the problem.
Sometimes simply knowing that you are willing to listen can make a big difference.
🌱 Explain that bodies develop differently
Children don’t all grow at the same speed.
Some children have growth spurts earlier, while others develop later. Puberty can also happen at different times.
This can be particularly difficult for children with IBD if their growth or puberty has been affected by active inflammation or nutritional difficulties.
Remind your child that being different from their friends doesn’t automatically mean something is wrong.
Their IBD team can monitor their growth and development and help determine whether anything needs attention.
🩺 Talk honestly about IBD-related body changes
Depending on their symptoms and treatment, your child may experience changes such as:
weight loss or weight gain
slower growth
delayed puberty
bloating or abdominal swelling
acne
changes in body shape
stretch marks
scars from procedures or surgery
changes in hair or skin
changes related to medications such as steroids.
Don’t pretend these changes aren’t happening.
A simple, honest explanation can help your child understand that their body hasn’t “failed” them.
For example:
“Your body has been dealing with a lot because of your IBD. Some of these changes may be part of your treatment or your body recovering. Let’s talk to your doctor if you’re worried.”
💊 Be careful when talking about medication changes
Some IBD medications can cause noticeable changes in appearance.
Corticosteroids, for example, can sometimes cause increased appetite, changes in body shape, acne or other temporary physical changes.
These effects can be particularly difficult for teenagers who are already sensitive about their appearance.
If your child is upset about a medication-related change, let their IBD team know.
Don’t stop or change prescribed medication because of appearance-related side effects without discussing it with the healthcare team.
The team may be able to explain what to expect, whether the change is temporary and whether there are ways to manage it.
🍽️ Avoid making food about weight
Food can become complicated for children with IBD.
A child may already have anxiety around eating because of abdominal pain, diarrhoea or urgency. Adding pressure to gain or lose weight can make that relationship with food even harder.
Try to focus conversations around:
energy
strength
nourishment
growth
feeling well
enjoying food.
Avoid labelling foods as “good” or “bad” or talking about needing to “burn off” food.
If your child needs nutritional support because of poor growth, weight changes or active IBD, a paediatric IBD dietitian can help.
🪞 Be aware of body checking
Some children may begin checking their body frequently.
They might:
repeatedly look in the mirror
weigh themselves often
compare their body with friends
pinch or examine parts of their body
frequently ask whether they look different
avoid mirrors or photographs
change their clothing to hide parts of their body.
Occasional self-consciousness is common, particularly during puberty.
But if body concerns are becoming a major part of your child’s day or affecting eating, school, friendships or activities, it’s worth talking with their healthcare team.
👕 Help them feel comfortable in their clothes
Clothing can make a surprisingly big difference to confidence.
Your child may feel uncomfortable with clothes that:
press against a painful or bloated abdomen
draw attention to weight changes
don’t fit after growth changes
make medical equipment or stomas difficult to manage
make them feel exposed or self-conscious.
Let your child have some control over what they wear.
Comfort doesn’t have to mean hiding their body. It’s about helping them feel physically and emotionally comfortable in what they choose.
🏫 Think about school and friendships
Body image concerns can become harder when children are surrounded by peers.
Your child may worry about:
changing clothes for sport
swimming
using the school bathroom
accidents
scars
taking medication at school
being smaller or taller than their friends
comments about weight or appearance.
If your child is worried about something happening at school, talk through possible solutions with them.
Their school may also be able to provide practical support and privacy where needed.
🏃 Help your child enjoy their body
Physical activity doesn’t need to be about weight.
Encourage activities that your child enjoys and that are appropriate for their health and IBD.
This could be:
swimming
walking
dancing
cycling
team sports
strength activities
playing outside
simply being active with friends.
The goal is to help children experience what their bodies can do, rather than focusing only on how their bodies look.
If your child is having an IBD flare, significant fatigue, pain or other symptoms, ask their healthcare team about appropriate activity levels.
❤️ Watch how you talk about your own body
Children notice how adults talk about their bodies.
If they regularly hear comments such as:
“I look terrible.”
“I need to lose weight.”
