what urinary disease the patient with Crohn disease is predisposed to?urinary stone
Crohn disease can develop fat malabsorption, leading to the increased lipids in the large intestine. These lipids can compete with oxalate for calcium binding in the GI tract, thereby causing decreased formation of calcium-oxalate aggregates (which are eliminated) and increased amounts of free oxalate (which is reabsorbed). Oxalate then must be eliminated in the urine at high concentrations, which can lead to the formation of calcium oxalate kidney stones. gastrointestinal Oct 9, 2019, 4:26 AM HirotoShishido

what is effective for prevention of colorectal cancerdaily aspirin therapy
Trials have shown that daily aspirin therapy is associated with reduced risk of colon cancer.
