How is chronic tummy pain in children diagnosed?

Your doctor will take a history including asking about what the pain is like, any other symptoms and family history. Your doctor will also want to know about how your child has been at school and at home, including your child's behaviour and mental health. 

Your doctor will examine your child's stomach and measure your child's growth. In some cases, a rectal examination may be needed. Your doctor will also do some tests, such as blood tests, taking a stool sample, urine (pee) test or an abdominal ultrasound. These tests are to rule out other diseases and to confirm any diagnoses depending on what your doctor thinks is causing the pain. 

How is chronic tummy pain in children treated?

If there is a physical or organic cause, treatment will focus on the underlying condition. If it is due to a functional cause, it can be managed by reassurance and explanation of the source of the pain.

Medicines are usually not needed, unless the pain is caused by an organic or a physical cause. In some cases, cognitive behavioural therapy from a psychologist can be helpful.  

There are some tips that to help manage chronic abdominal pain in children:

  • Keep a diary and record the intensity, triggers, timing, duration and relieving factors of your child's pain.  It can be useful to bring this to your doctor’s appointment.
  • Encourage healthy behaviours such as a balanced diet and physical activity.
  • Avoid reinforcing pain or pain behaviours. Reassure your child the pain will ease and encourage them to continue their normal activities.
  • Chronic abdominal pain usually happens in the morning and lasts less than an hour, so bring your child to school when the pain starts to settle.
  • Encourage school attendance.
  • Gain support from school teachers and discuss a plan to manage abdominal pain in school. 

Your doctor will also ask for regular follow-up appointments to make sure that your child's pain is settling. If your child's pain gets worse or new symptoms arise, tell your doctor as this may suggest an underlying physical or organic cause.
