Food Sensitivity Testing
Why Test IgG Food Sensitivity?
We have seen evidence to support the clinical benefits of eliminating IgG reactive foods from the diet. IgG food sensitivities have been implicated in many symptoms, such as migraine headaches, irritable bowel syndrome, bloating, indigestion, fatigue, eczema, weight gain and/or difficulty losing weight. Because IgG food reactions take hours or days to develop, it is difficult to determine which food is responsible for the reaction, so many of our patients choose to have this testing.
What is Food Sensitivity Testing (IgG Testing)?
Food sensitivities are delayed reactions to specific foods that are triggered by IgG antibodies. In an IgG reaction, the IgG antibodies attach themselves to the food antigen and create an antibody-antigen complex. These complexes are normally removed by special cells called macrophages. However, if the antigens are present in large numbers and the reactive food is still being consumed, the macrophages can’t remove them quickly enough. The food antigen-antibody complexes accumulate and are deposited in body tissues. Once in tissue, these complexes release inflammation-causing chemicals, which may play a role in numerous diseases and conditions.
