IgG food sensitivities have been implicated in migraine headaches and irritable bowel syndrome (alternating diarrhea and constipation). Bloating and indigestion are also common food sensitivity reactions, as is fatigue. Continued consumption of reactive foods may contribute to weight gain and/or difficult losing weight. Ezcema is also commonly associated with food reactions.
IgA Food Reactions
Because IgA is the immunoglobulin of the mucous membranes, IgA reactions often result in digestive symptoms like abdominal discomfort, irritable bowel and bloating. Runny nose and excess mucous may also be signs of an IgA food reaction.
Both gluten sensitivity and celiac disease are reactions to proteins found in wheat gluten. Abdominal pain, irritable bowel, and weight loss are just some of the symptoms associated with gluten sensitivity and celiac disease.
Having elevated IgG antibodies to candida suggests there may be a recent or current fungal infection. Some people experience fatigue, headache, depression and/or foggy memory with chronic exposure to Candida. Elevated IgG antibodies to Candida have been associated with poorer prognosis in cancer patients., although the presence of antibodies has not been shown to increase risk for developing cancer.
