Inflammatory bowel disease (IBD) could be down to genetics, a study by Southampton University has suggested.
Researchers said tests on 500 children who had serious problems digesting their food showed that the condition often affected members of the same family.
The study hopes to find the genetic code behind IBD which includes Crohn's disease and ulcerative colitis.
