IgG antibody testing can be used to alleviate symptoms of ulcerative colitis, as well as IBS

30 patients attending Shijitan Hospital in Beijing for ulcerative colitis or Irritable Bowel Syndrome (IBS) were tested for IgG antibodies against foods as well as for positive skin tests. The patients were asked to avoid foods that showed up as positive in the IgG test and followed up after 3 and 6 months. 73.3% of them showed significant improvement in their condition, notably abdominal pain.

Egg was positive in 13 patients, wheat in 8, tomatoes in 4, 3 patients each reacted to beans and fish and 2 each to shrimp, peanut, corn and beef. 

The authors concluded that IgG blood antibody testing is a valuable tool and that the results highlight the close relationship between food allergy and digestive tract disease.

Comment: The study had the general goal of demonstrating a link between food allergy and gut disease, and unfortunately did not clearly compare how strong the link was in the two separate conditions. They also did not have a control group of patients to compare the results to. However, they did observe that the outcome improved further between 3 and 6 months, such that 22 of the 30 considered they had recovered, which suggests that an exclusion diet based on IgG food antibody testing would be worth a try in either condition.
