> Weakened intestinal barrier, systemic immune activation may explain symptoms in people without celiac disease The immune activation is likely caused by a response to the gut biome. One theory is that certain foods are not well absorbed by the digestion system, leading to an overabundance of food for the gut biome. This leads to bacterial overgrowth (or imbalance), causing an immune response. It's this immune response that causes the negative symptoms.
