‘I’ve got a sore tummy’ – it’s a common complaint in childhood. Often, you don’t need to be concerned, but you should take your child to the GP if the stomach pain is severe or doesn’t go away, or if your child also seems generally unwell.

Causes of stomach pain or ache

Stomach pain in children is very often caused by excessive gas and indigestion, neither of which is serious.

A sore tummy might also be a sign of infections like food poisoning, gastroenteritis, pneumonia or urinary tract infections.

Anxiety or stress can cause ‘butterflies’ in the tummy.

Severe stomach pain might be caused by more serious or surgical illnesses like appendicitis or intussusception, which is when part of the gut slides into or over itself.

Tummy pain that keeps coming back might be associated with constipation, food intolerances or inflammation in the gut.

In adolescent girls, stomach pain can have several gynaecological causes, including a twisted ovary, ectopic pregnancy and period pain.

Sometimes doctors won’t be able to work out what’s causing your child’s sore tummy. This is called functional abdominal pain. In these cases, nerve signals or chemicals might be making your child’s gut more sensitive to normal triggers like gas. Or it could be stress or anxiety.

Symptoms related to stomach pain

Stomach pain varies according to its specific cause.

The symptoms that come with stomach pain might include nausea, vomiting, diarrhoea, fever, constipation, bloating and loss of appetite. These also vary depending on the underlying cause of the stomach pain.

A sore tummy is more likely to be a sign of something serious if it wakes your child up, or if the pain is in a specific area of the abdomen, away from your child’s belly button. For example, in appendicitis, the pain is usually sharp, and the pain often starts in the middle then moves to the lower right section of the abdomen. Your child might also have fever, loss of appetite and vomiting.

If the stomach pain comes with loss of appetite, nausea, vomiting and diarrhoea, the problem could be gastroenteritis or food poisoning.

Cramps and general pain might be associated with excess gas.

Tummy pain that doesn’t go away could be constipation or a urinary tract infection. If your child has a urinary tract infection, she might also have pain when doing a wee, be doing more wees than normal, and might have a fever, be vomiting and feel irritable.

Tummy pain might also be associated with pneumonia or a viral infection. In this case, your child will probably also have a fever, cough and possibly a sore throat.

In all types of stomach pain, there’s a risk that your child will become dehydrated. You should watch for signs of dehydration, including sunken eyes, less wee than usual, lethargy and weight loss, and make sure your child is drinking enough fluids.

When to see you doctor about stomach pain

You should take your child to see your GP if your child:

  • complains of severe pain in the tummy or it wakes him from sleep
  • has tummy pain that doesn’t go away, or that keeps coming and going
  • is unwell or has a fever in addition to the pain
  • complains that the pain gets worse when he moves
  • has diarrhoea or vomiting that doesn’t go away
  • has bloody or bright green-coloured vomit
  • has blood in his poo
  • might have swallowed something poisonous
  • is losing weight or has pain that affects his energy levels.

Treatment for stomach pain

Treatment depends on the specific cause of the stomach pain.

Don’t give your child any medications for pain until you’ve talked with your doctor. Painkillers might make it harder to work out what the underlying problem is.
