Digestive complaints are among the most common reasons parents bring children to a pediatrician — from a baby who spits up after every feed, to a school-age child with recurring tummy aches. Most of these issues are common and manageable, but understanding what's typical and what's a warning sign helps you know when to seek further evaluation.
Reflux (GER and GERD)
Gastroesophageal reflux — milk or stomach contents coming back up — is extremely common in babies, affecting most infants to some degree in the first few months. This usually improves significantly by 12-18 months as the muscle between the stomach and oesophagus matures. It becomes gastroesophageal reflux disease (GERD) when it causes problems such as poor weight gain, persistent irritability during/after feeds, feeding refusal, or breathing symptoms — in which case it warrants evaluation and possibly treatment.
Diarrhoea & Vomiting
Usually caused by viral infections (see our guide on common childhood infections) and self-limiting within a few days. The main risk is dehydration. Offer small, frequent sips of fluids (oral rehydration solution if recommended), continue breastfeeding if applicable, and reintroduce normal food as tolerated. Seek medical attention if there's:
- Signs of dehydration — reduced urination, dry mouth, no tears, sunken eyes, lethargy
- Blood in the stool or vomit
- High fever or severe abdominal pain
- Diarrhoea lasting more than a few days, or any significant diarrhoea in a baby under 3 months
Recurrent Abdominal Pain
Very common in school-age children, and in most cases not caused by a serious underlying condition — often related to constipation (see our constipation guide), diet, or stress/anxiety ("functional abdominal pain"). However, certain features warrant further evaluation:
- Pain that wakes the child from sleep
- Pain associated with weight loss, poor growth, or blood in stool
- Pain localised away from the belly button, especially the lower right side
- Associated fever, vomiting, or diarrhoea that doesn't resolve
- Family history of inflammatory bowel disease or celiac disease
Food Intolerances & Sensitivities
Intolerances (such as lactose intolerance) involve difficulty digesting certain foods, causing symptoms like bloating, gas, loose stools, or abdominal discomfort — usually hours after eating, and not immediately dangerous. This is different from a food allergy, which involves the immune system and can cause rapid reactions, including hives, swelling, or in severe cases, difficulty breathing — a medical emergency. If you suspect either, discuss it with your pediatrician, as both can usually be confirmed and managed with the right approach.
Liver Problems in Children
Jaundice Beyond the Newborn Period
Jaundice (yellowing of the skin and eyes) is common and usually harmless in the first 1-2 weeks of life. However, jaundice appearing after this period, or persisting beyond 2-3 weeks, is different — it always warrants evaluation, as it can point to liver conditions, bile duct problems, infections, or certain blood conditions.
Hepatitis
Inflammation of the liver, most commonly caused by viral infections (Hepatitis A, B, C, etc.). Hepatitis A is typically spread through contaminated food or water and usually causes a short-term illness; Hepatitis B and C can become chronic if not identified and managed. Vaccination against Hepatitis A and B (part of the recommended schedule — see our vaccination guide) significantly reduces risk.
Signs of Liver Problems
- Yellowing of skin or eyes (jaundice) beyond the newborn period
- Pale/clay-coloured stools or dark urine
- Persistent fatigue, poor appetite, or itching
- Abdominal swelling or pain in the upper right side

How These Conditions Are Diagnosed
- History and examination — often the most important step, looking at pattern, timing, and associated symptoms
- Blood tests — to check for infection, anemia (see our blood problems guide), liver function, or markers of inflammation
- Stool tests — to check for infection, blood, or absorption problems
- Ultrasound — to look at the liver, gallbladder, and abdominal organs when needed
- Specialist referral — to a pediatric gastroenterologist for more complex or persistent cases
Most digestive complaints in children are manageable with simple measures and time — but persistent, severe, or unusual symptoms deserve a proper evaluation rather than guesswork.
