Functional Abdominal pain (FAP) can be acute pain, meaning it happened all of a sudden, or it can be chronic or long term.[1]

FAP refers to recurrent tummy pain in children that is not caused by any disease process. Pain that is caused by a disease process is called organic pain rather than functional pain.[2]

Who gets affected

Functional pain in the abdomen is seen in children from the age of 3 to 4 years. There is no serious underlying cause and few investigations are required.


For functional dyspepsia, anti-acid medication may be tried.

For irritable bowel syndrome, agents that affect bowel habit may be tried. If your child is constipated, you can read more by .

For abdominal migraine, pizotifen might be tried. This has been shown in one small study to reduce the frequency of painful episodes and reduce the severity of pain when the child gets it. You might also want to look for trigger factors.[3]
