Inflammatory Bowel Disease - The How and Why
from Colorectal Surgery Review · host Allen Kamrava, MD MBA FACS FASCRS
A high-yield look at the molecular and environmental drivers of IBD, moving beyond simple autoimmune definitions. We explore the "four pillars" of pathogenesis, including the NOD2 gene's role in autophagy defects and the specific dysbiosis signatures (low Firmicutes, high Proteobacteria). The episode explains the global rise of IBD in newly industrialized nations and how understanding specific pathways, like the IL-23/Th17 axis, dictates modern biologic therapy and surgical timing.
