Igg Food Antibody Guided Elimination-Rotation Diet Was More Effective than FODMAP Diet and Control Diet in the Treatment of Women with Mixed IBS-Results from an Open Label Study.

Journal of clinical medicine. 2021;10(19)

IBS, also known as irritable bowel syndrome, is a debilitating condition characterised by abdominal pain, irregular bowel movements, and changes in the consistency of stool. Symptoms of IBS may appear shortly after eating a meal. Excluding foods high in FODMAP carbohydrates, such as fermentable oligo- and di-saccharides, mono- and disaccharides, and polyols, or following an elimination rotation diet to reduce IgG-dependent food hypersensitivity, which has been shown to improve IBS symptoms previously. The purpose of this open-label study is to investigate the effectiveness of a low-FODMAPS diet and an elimination rotation diet based on IgG as well as a control diet in reducing symptoms of IBS. During the eight-week study, 73 female subjects with a mix of IBS were assigned to either of the three dietary treatments. Compared to the other diet groups, the IgG based elimination rotation diet group showed a significant improvement in the IBS symptoms and comorbid symptoms after the intervention period. In order to determine whether IgG-mediated food hypersensitivity plays a role in IBS and the efficacy of an IgG-dependent elimination rotation diet in the general population, further robust research is required. Healthcare professionals, however, can make use of these results to gain a better understanding of how an IgG based elimination diet tailored to each individual can improve IBS symptoms.
