stomach in children

Overview

Stomach problems in children are any symptoms in the belly area, such as pain, cramping, bloating, nausea, vomiting, or diarrhea. Most are short-lived and caused by mild infections or everyday issues like constipation. This article explains common stomach complaints in children and when to seek help.

Yes, stomach problems in children are very common. Almost every child will have a tummy ache or an upset stomach at some point.

Stomach problems can affect children of all ages, from babies to teenagers. The causes often vary by age.

Symptoms

Common symptoms

• Belly pain or cramps
• Bloating or a swollen belly
• Nausea or feeling sick
• Vomiting
• Diarrhea
• Constipation
• Fever
• Loss of appetite

Symptoms in children

• Tummy pain that comes and goes
• Complaining of pain around the belly button
• Crying more than usual, especially in babies
• Curling up or lying still to ease pain
• Not wanting to eat or drink
• Changes in poo – harder, softer, or more frequent than normal

Symptoms in older adults

• This article focuses on children, but stomach symptoms in older adults can have different causes. In older people, belly pain may be a sign of conditions like ulcers, gallbladder problems, or heart issues, so it should always be checked by a doctor.

Causes

Main causes

• Viral gastroenteritis – sometimes called the 'stomach flu' – a common infection that causes vomiting and diarrhea
• Constipation, which is very common in children
• Food poisoning from undercooked or contaminated food
• Acid reflux or heartburn
• Lactose intolerance or trouble digesting certain foods
• Gas or trapped wind
• Appendicitis – an inflammation of the appendix (rare but serious)

Risk factors

• Being in daycare, preschool, or school, where infections spread easily
• Not washing hands often, especially after using the toilet or before eating
• Drinking untreated water or eating unsafe food
• A family history of digestive problems like celiac disease or inflammatory bowel disease
• Stress or anxiety, which can affect the stomach

When to see a doctor

See a doctor urgently if:

• If your child has severe pain, high fever, blood in vomit or stool, or signs of dehydration, call your local emergency number right away.
• If your child is under 3 months and has a fever, vomiting, or diarrhea, call your doctor immediately.

Book a routine appointment if:

• Make a same-day appointment if your child has belly pain that lasts more than a few days, repeated vomiting, or ongoing diarrhea without signs of dehydration.
• Seek medical advice if your child is losing weight or not growing as expected.
• See a doctor if belly pain wakes your child from sleep or happens more than once a month.

Diagnosis

A doctor will ask you and your child about the symptoms, how long they've lasted, and what makes them better or worse. They will gently feel your child's belly and listen to their tummy with a stethoscope.

Tests that may be done

• Stool (poo) sample to check for infection or inflammation
• Urine test to rule out a urinary tract infection
• Blood tests to look for signs of infection or dehydration
• Ultrasound of the belly to see the organs
• Breath test for lactose intolerance or other food intolerances

What to expect at your appointment

The doctor will explain what they find and may recommend home care or further tests. In most cases, no test is needed, and the doctor will simply advise on fluids and rest.

Treatment

Treatment depends on the cause of the stomach problem. For most common tummy upsets, care at home with fluids and rest is enough. If there is a specific condition like reflux or a bacterial infection, the doctor will suggest a treatment plan.

Self-care at home

• Give small, frequent sips of water or an oral rehydration solution (available at pharmacies) to prevent dehydration.
• Let your child rest as much as possible.
• Offer bland foods like bread, rice, bananas, or crackers once vomiting has stopped.
• For constipation, encourage more water and high-fiber foods like fruits and vegetables.
• Use a warm compress or gentle massage on the belly only if it helps and your child is comfortable.
• Do not give any medicine to stop vomiting or diarrhea unless a healthcare provider tells you to.

Medical treatments

Doctors may suggest rehydration products, antacids for reflux, laxatives for constipation, or antibiotics for bacterial infections. Never give these without a doctor's advice, and always follow the dosage for your child's age and weight.

When is surgery considered?

Surgery is rarely needed for stomach problems in children. In some cases, conditions like appendicitis or an intestinal blockage may require surgery, but this is not common.

Living with this condition

When your child has a stomach problem, keep things calm and comfortable. Offer fluids regularly and let them decide when they are ready to eat. Keep an eye on how often they pee and whether they seem alert and active.

Lifestyle tips

• Encourage regular handwashing with soap and water, especially before meals and after using the toilet.
• Make sure your child gets enough sleep, as tiredness can make tummy symptoms feel worse.
• Help your child manage stress with calm routines, talking, and breathing exercises if they feel anxious.
• Keep up to date with recommended vaccinations for children.

Diet and exercise

A balanced diet with plenty of fruits, vegetables, whole grains, and water helps keep the digestive system healthy. Regular physical activity also supports good digestion. After a stomach bug, ease back into normal meals slowly.

Mental health and emotional wellbeing

Stomach pain and digestive symptoms can affect a child's mood, sleep, and confidence. They may worry about going to school or joining in activities. It helps to listen to your child's worries and let them know that feeling upset is normal.

Prevention

Not all stomach problems can be prevented, but you can reduce the risk by practicing good hand hygiene, preparing food safely, and ensuring your child drinks clean water.

Vaccines

In many countries, a rotavirus vaccine is offered to babies to protect against a common cause of severe diarrhea and vomiting. Ask your healthcare provider about which vaccines are recommended for your child.

Complications

If left untreated

• Dehydration – when the body loses too much water, which can be dangerous if not treated
• Electrolyte imbalance – loss of important salts the body needs to work properly
• Pain or discomfort that continues and affects daily life
• Worsening of an underlying condition, such as appendicitis, if delayed

Long-term outlook

With the right care, most children with stomach problems recover fully within a few days and go back to normal activities. Even when a specific condition is found, many digestive issues can be managed well with a doctor's help, so children can grow, play, and feel good.
