What Actually Causes IBD? A Mechanistic Reading of Crohn's Disease and Ulcerative Colitis — thesis

IBD is not a single autoimmune disease. At the cellular level both Crohn's and ulcerative colitis are dominated by colonocyte bioenergetic failure — loss of butyrate oxidation, collapse of the gut oxygen gradient, and the inflammatory cascade that follows. A mechanistic reading anchored in primary research from Roediger 1990 onward, and why standard immunosuppression contains the response but does not restore the upstream lesion.
