Diet for Children with GI Conditions

How you feed matters as much as what you feed. These habits are supported by paediatric feeding guidance and are safe for all children.

• Offer regular meals and planned snacks, at about the same times each day, and limit grazing and milk or juice between meals so the child comes to the table hungry.
• Eat together as a family when possible, without screens, and let the child see you enjoying a variety of foods.
• Offer new foods many times (often 10 or more) without pressure, bribes or punishment. Pressure to eat tends to make refusal worse.
• Check growth regularly with your child’s doctor or clinic and keep the growth chart; growth is the best sign that intake is enough.
• Keep a simple food and symptom diary for 1 to 2 weeks before the appointment, rather than cutting foods out in advance.
• Encourage daily play and activity, and for constipation a regular toilet routine after meals, as advised by your doctor.

Start from a normal, varied, family diet. Changes below are the general principles per condition; your child’s own team decides what applies.

• Coeliac disease: after a confirmed diagnosis, a strict lifelong gluten-free diet (wheat, barley, rye, and oats unless certified gluten-free). Do not start it before testing, because it can make the tests unreliable. Ask for dietitian support, and check labels, shared fryers and school canteen food. See the article on coeliac disease in children.
• Cow’s milk allergy: avoid cow’s milk protein only if the diagnosis is likely or proven, with the right formula for babies and a calcium and vitamin D plan for older children. Breastfed babies should keep breastfeeding; the mother’s dairy avoidance should be guided by a dietitian. Re-introduction is planned by the doctor. See the article on cow’s milk protein allergy.
• Eosinophilic oesophagitis: treatment may include a food elimination diet (commonly starting with cow’s milk), but only under specialist and dietitian supervision, with repeat endoscopy to learn which foods matter, then careful re-introduction.
• Crohn’s disease and ulcerative colitis: there is no single “IBD diet”. In children, exclusive enteral nutrition can treat active Crohn’s disease. Otherwise aim for a balanced, calorie- and protein-rich diet, and add targeted restrictions (for example during a stricture) only on your team’s advice.
• Constipation: normal amounts of fruit, vegetables, wholegrains and legumes, plus normal drinking; do not force bran or large amounts of water. Limit milk to the recommended amount in toddlers if it replaces meals. The medicine given by the doctor is usually what fixes it.
• Baby reflux: for a baby who is happy and gaining weight, no special diet is needed. Smaller, more frequent feeds, burping, and keeping upright after feeds can help; ask before trying thickeners or a different formula. Do not give home thickeners to young babies without the doctor’s advice.
• Functional tummy pain: eat regular, balanced meals, avoid long gaps and very large meals, and limit caffeine and fizzy drinks. Strict diets, lactose avoidance or gluten avoidance are not recommended unless a test shows a reason.
• Avoid fad diets (detox, “clean” or sugar-free plans, social-media elimination diets) and unsupervised elimination of milk, wheat, eggs or other major foods. Unnecessary restriction can cause poor growth, vitamin and mineral deficiency, anxiety around food, and can hide the real diagnosis.
• Picky eating or a medical problem? Fussy eating with normal growth, energy and a variety of at least some foods is usually a normal phase of toddler years. See a doctor if growth is slowing, the child gags, chokes or vomits at meals, eats a very narrow list of foods, or avoids whole food groups.
• School lunches: pack a balanced box (a protein such as egg, cheese, chicken or labneh; a starch; fruit or vegetables; water), keep it cool with an ice pack, and wash hands first. For gluten or allergen restrictions, send safe food, tell the school nurse and teachers in writing, and teach the child not to swap food. Follow the school’s allergy rules (some schools restrict nuts).
• Ramadan for children: children before puberty are not required to fast. Healthy older children may practise a few hours gradually, but fasting is generally not advised for children with IBD, coeliac disease that is not yet well controlled, diabetes, kidney or liver disease, poor growth, or those taking time-critical medicines. Speak to your child’s doctor first and never let a child hide that they are unwell.
• See a paediatric dietitian when there is faltering growth, a diagnosed condition needing a special diet, more than one food being avoided, tube or formula feeding, or when the family is struggling with feeding.

Medicines for children are prescribed by their doctor according to weight and condition. We give no doses here.

• Do not give laxatives, acid-blocking medicines, probiotics or herbal remedies to a child without medical advice. For constipation, treatment is usually a prescribed osmotic laxative given for long enough, not stopped as soon as stools soften.
• Do not use anti-diarrhoea medicines in young children unless the doctor says so; oral rehydration solution is the key treatment for diarrhoea.
• Vitamin D, iron, calcium and other supplements may be needed with restricted diets or in IBD and coeliac disease; take them only as advised and keep them out of children’s reach.
• Treat IBD, eosinophilic oesophagitis and reflux medicines exactly as prescribed, and tell the team if the child cannot take them.

Most children never need a procedure. When needed, they are done by paediatric specialists.

• Upper endoscopy with biopsies is used to diagnose eosinophilic oesophagitis, and sometimes coeliac disease.
• Colonoscopy and imaging help to diagnose and monitor IBD.
• Supervised food challenge in hospital checks whether a child has outgrown an allergy.
• A feeding tube (nasogastric or gastrostomy) may be used when a child cannot take enough by mouth, under the nutrition team.
