Abdominal pain or tummy pain is a common symptom that children complain of. Most tummy pain is benign and not caused by pathology or disease. However, the pain is still real. We call tummy pain that is not caused by disease functional pain as opposed to organic pain which relates to disease/pathology.

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.
Organic causes of pain in the abdomen include:
Another common cause of tummy pain in children is constipation, so if your child does not have regular soft formed bowel motions, go to the constipation page. For an overview of what causes tummy pain in children, click here.
On the other hand, FAP (functional pain in the abdomen) in children includes the following:
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.
Yes. The pain is real. It just isn't caused by any disease process. Headaches are very real, as you will be aware, but there is no disease process causing them - just some people are prone to them. The same is true of functional pain in the abdomen.
Functional tummy pain is non-specific pain that is not associated with any alarming symptoms or signs. The following signs and symptoms would be considered alarming and so a search for another cause of pain should be sought:
Your doctor will take a history of the pain and associated features and do a physical examination. Some baseline investigations may be performed, such as a stool test looking for occult blood, a blood count, kidney and liver function, inflammatory markers (ESR and CRP). These tests will not diagnose functional tummy pain but will reassure if they are normal.
There is no specific treatment that will work all the time. Sometimes, all that can be achieved is ensuring your child's life is affected as little as possible due to the pain.
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 clicking here.
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 - read more..
There have been studies looking at dietary changes, such as fiber supplements and lactose-free diets, but these have not shown conclusive benefits.
One study looking at probiotics, did show that Lactobacillus rhamnosus (Lactobacillus GG) when given to children with functional pain in the abdomen, did reduce frequency of the pain and more children were thought to have successful treatment of their tummy pain compared to those taking a dummy medication (placebo).
Probiotics are relatively safe and I advise parents of children with functional abdominal pain to try them.
