The symptoms of blood in the stool after eating chili peppers are mainly related to increased intestinal peristalsis and vasodilatation of local trauma stimulation. Cayenne pepper contains capsaicin, which has the effect of stimulating the gastrointestinal tract, and after eating chili peppers patients will experience increased intestinal peristalsis, which increases the local pulling strength and increases the risk of bleeding. While stimulating intestinal peristalsis, capsaicin acts directly on intestinal blood vessels, increasing intestinal vascular permeability and dilatation, increasing the risk of rupture and bleeding. Patients with chronic intestinal inflammation will have chili peppers adhering to local wounds after eating chili peppers, causing irritation, and the wounds will have increased exudate after being irritated. It is recommended that patients with blood in the stool and chronic gastrointestinal lesions consume a small amount of spicy and irritating foods, such as chili peppers, during the eating process.
