What is diarrhea when you eat greasy food?

When the patient eats greasy things, he shows diarrhea. The main consideration is that the patient's intestinal function is poor. It is easy for the patient to show indigestion after ingesting some indigestible or greasy foods, so that the intestinal contents will directly stimulate the intestinal mucosa and smooth muscle of the intestinal tract, causing it to show spasm or increase its motility, so that the patient will expel the ingested food from the body in a short time. In addition, the patient also considers that there are some irritating substances in the diet structure, which will directly stimulate the intestinal mucosa of the patient, resulting in functional disorders. Therefore, it is necessary to adjust the diet structure as much as possible.
