Can certain foods trigger my IBD symptoms?

Have you ever eaten something and then noticed your tummy started hurting, you felt bloated, or you needed to rush to the toilet? When you have inflammatory bowel disease (IBD), you might notice that some foods seem to make your symptoms worse. This can be confusing, especially when your friends can eat the same foods without any problems.

The good news is that you don't have to avoid every food that might upset your tummy. Learning how your body responds to different foods can help you manage your symptoms without missing out on the foods you enjoy.

🍎 Can certain foods trigger IBD symptoms?

Yes, some foods can make IBD symptoms feel worse for some people. However, everyone is different, and a food that bothers one person might be completely fine for someone else.

Foods that some people find harder to tolerate include:

• Spicy foods: These can sometimes increase tummy discomfort or diarrhoea.

• Fatty or fried foods: These may make diarrhoea, bloating or nausea worse.

• Dairy products: Milk, ice cream and other dairy foods can cause wind, bloating or diarrhoea if you have difficulty digesting lactose.

• High-fibre foods: Raw vegetables, nuts, seeds and wholegrains may be harder to tolerate during a flare, particularly if you have a narrowing in your bowel.

• Fizzy drinks: These can increase wind and bloating.

• Caffeinated drinks: Drinks such as coffee and energy drinks may make you need the toilet more often.

This doesn't mean these foods are bad for you or that you need to stop eating them. You might tolerate them perfectly well, even if you have IBD.

🔥 Does a food trigger mean my IBD is getting worse?

Not necessarily! This is an important difference to understand.

A food can make your symptoms worse without increasing the inflammation in your bowel.

For example, you might eat a meal and notice that you have more wind, bloating or diarrhoea afterwards. This doesn't automatically mean your IBD is flaring.

IBD symptoms can be caused by inflammation, changes in digestion, food intolerances and other factors. Sometimes, it can be difficult to tell what's causing the problem just by how you feel.

If your symptoms are becoming more frequent or severe, tell your parent or carer and contact your IBD team. They can help you work out what's happening.

🩺 Why do my food triggers change?

You might find that a food bothers you one week but doesn't cause any problems another time. This can happen for several reasons.

During a flare: Inflammation can make your digestive system more sensitive. You might find it harder to tolerate certain foods, particularly those that are high in fibre or fat.

When your IBD is under control: You may be able to eat a wider variety of foods without experiencing symptoms.

When your body is changing: Growth, hormones, stress, sleep and other factors can affect how you feel.

Your food triggers might also be different from those of someone else with Crohn's disease or ulcerative colitis. There is no single list of foods that everyone with IBD needs to avoid.

📝 How can I work out which foods affect me?

If you think certain foods are making your symptoms worse, noticing patterns can help.

You could try keeping a simple food and symptom diary for a short time. Write down:

• What you ate and drank.

• Any symptoms you noticed.

• When the symptoms started.

• Whether you were feeling well or having a flare.

• Anything else that might have affected how you felt, such as stress or poor sleep.

You don't need to record every single thing you eat forever. Even a short diary can help you and your healthcare team spot patterns.

Try not to blame a food after just one uncomfortable experience. Your symptoms might have another cause, and looking for patterns over time can give you a clearer picture.

🍽️ Should I stop eating foods that trigger my symptoms?

Not necessarily. Before cutting out a food, think about how often it causes problems and how it affects you.

Sometimes, a small change can help. For example, you might find that cooked vegetables are easier to tolerate than raw vegetables, or that a smaller meal feels more comfortable than a large one.

If a food consistently causes problems, your IBD team or dietitian can help you find alternatives.

Avoid cutting out lots of foods or entire food groups without getting advice. Your body needs enough energy, protein, vitamins and minerals to grow, develop and stay healthy. Restricting too many foods can make it harder to get everything you need.

If you have a bowel narrowing or have been given specific dietary advice, follow the plan recommended by your healthcare team.

🥛 What if I think I have a food intolerance?

Sometimes, symptoms after eating are caused by a food intolerance rather than IBD inflammation.

For example, some people have difficulty digesting lactose, a natural sugar found in milk and some dairy products. This can cause bloating, wind, tummy pain and diarrhoea.

If you suspect a food intolerance, talk to your parent or carer and your healthcare team before making significant changes to your diet. They can help you work out whether an intolerance might be involved and how to keep getting the nutrients you need.

You shouldn't have to put up with uncomfortable symptoms, but you also shouldn't have to miss out on foods unnecessarily.

🎒 What if I get symptoms at school or when I'm out?

Worrying about food can make school lunches, parties, sleepovers and eating out feel more difficult.

A little planning can help you feel more confident.

• Choose foods you know you tolerate well when you need to feel comfortable.

• Keep snacks available if you sometimes struggle to eat a full meal.

• Check menus before going to a restaurant.

• Talk to your parent or carer about foods that make you feel unwell.

• Let a trusted adult know if symptoms are affecting your school day or social activities.

You don't have to explain your IBD or your food choices to everyone. It's okay to keep things private if that's what you prefer.

💚 Do I need to eat a perfect diet to manage my IBD?

Absolutely not! There is no perfect diet that works for every person with IBD.

Food is about more than symptoms. It also gives you energy, supports your growth and lets you enjoy meals with family and friends.

It's okay if you need to make changes sometimes. It's also okay to enjoy your favourite foods when they agree with you.

The aim isn't to create a long list of foods you're not allowed to eat. It's to understand your body, find what works for you and make sure you're getting the nutrition you need.

🩺 When should I ask for help?

Talk to your parent or carer, IBD nurse, doctor or dietitian if:

• You regularly feel unwell after eating.

• Your diarrhoea or tummy pain is getting worse.

• You're losing weight without meaning to.

• You're avoiding more and more foods.

• You're worried about eating or getting enough nutrition.

• You're unsure whether your symptoms are caused by food or a flare.

Seek urgent medical advice if you have severe or worsening abdominal pain, significant bleeding, repeated vomiting or signs of dehydration.

Your healthcare team can help you understand your symptoms and decide what to do next.

⭐ Remember

Some foods can trigger symptoms, but that doesn't mean every food that upsets your tummy is making your IBD worse.

Pay attention to how you feel, look for patterns and ask for help when you need it. You don't have to figure everything out on your own.

You deserve to enjoy food without feeling worried about every bite.
