(1) Bacterial infection may occur after people consume food contaminated with bacteria such as E. coli, Salmonella, Shigella, or drink beverages contaminated with bacteria, resulting in various degrees of abdominal pain, diarrhea, vomiting, urgency, fever and other symptoms.
(2) Viral infections can easily cause viral diarrhea after the human body is infected with various viruses through food or other means, such as rotavirus, norovirus, coxsackievirus, echovirus, etc. Symptoms such as abdominal pain, diarrhea, nausea, vomiting, fever and general malaise can occur.
(3) Food poisoning is an acute toxic disease caused by eating food contaminated with bacteria and their toxins, or ingesting undercooked lentils. Spoiled food and contaminated water are the main sources of infection, and unclean hands, utensils and flies are the main means of transmission. Patients can appear vomiting, diarrhea, abdominal pain, fever and other acute gastrointestinal symptoms.
(4) Cold food, cold food and cold beer can lead to gastrointestinal dysfunction, accelerated intestinal motility and diarrhea.
(5) Food retention indigestion, irregular diet, eating too much, eating indigestible food, or food retention in the stomach due to insufficient gastric power, causing bloating, diarrhea, nausea, vomiting, acid reflux, heartburn, belching (burping) and other symptoms.

(1) chronic amoebic dysentery.
(ii) Chronic bacterial diseases.
(iii) intestinal tuberculosis.
④ Pear-shaped flagellosis, schistosomiasis.
⑤ intestinal candidiasis.
(2) non-infectious inflammatory diseases of the intestine
① inflammatory bowel disease (Crohn’s disease and ulcerative colitis)

④diverticulitis.
⑤ uremic enteritis.
(3) Tumor
①colorectal cancer.
(ii) colonic adenomatosis (polyps).
(iii) malignant lymphoma of the small intestine.
④amine precursor uptake decarboxylation cell tumor, gastrinoma, carcinoid tumor, intestinal vasoactive intestinal peptide tumor, etc.
(4) Small intestinal malabsorption
(1) primary small intestinal malabsorption.
② secondary small intestinal malabsorption.
