Acute diarrhea

1. The course of acute diarrhea usually does not exceed 3 weeks. Intestinal infection, including food poisoning, is the most common cause of acute diarrhea, which can be divided into:

1. Bacterial infection: Common pathogens include Shigella dysenteriae, Escherichia coli, Salmonella, Campylobacter intestinalis, Yersinia enterocolitica, Staphylococcus aureus, Clostridium perfringens, Clostridium difficile, Vibrio cholerae, etc.

2. Protozoan and parasitic infections: including amoeba, schistosoma, trichomonas, and giardia pirinae.

3. Viral infection: more common in intestinal rotavirus infection and intestinal adenovirus infection.

4. Fungal infection: There are many fungi that can cause diarrhea, such as mold in expired food.

5. Food poisoning: Common pathogens include Staphylococcus aureus, Salmonella, Halobacterium, Bacillus cereus, Clostridium perfringens or Clostridium botulinum; poisonous mushrooms, puffer fish, large fish gallbladders, rat poison, pesticides and other toxic chemical toxins.

6. Allergic reactions: Food allergies (milk, fish, shrimp, seafood products, etc.) can cause abdominal pain and diarrhea; diseases such as allergic purpura can be accompanied by increased intestinal motility and diarrhea.

7. Drugs: Many drugs can cause diarrhea, such as erythromycin, magnesium hydroxide, neomycin, lincomycin, magnesium sulfate, sorbitol, mannitol, 5-fluorouracil, reserpine (reserpine), propranolol (propranolol), etc. The mechanisms by which these drugs cause diarrhea are different; certain chemicals such as phosphorus, arsenic, mercury and alcohol poisoning can cause acute diarrhea.

2. Chronic diarrhea

1. Intestinal infection: It is the most common cause of chronic diarrhea, including bacterial infection, protozoan and parasitic infection, and fungi.

2. Nonspecific or non-infectious inflammation of the intestine: autoimmune diseases, autoimmune diseases, enteritis caused by radiotherapy, malabsorption syndrome, etc.

3. Malabsorption syndrome: The classification of malabsorption syndrome is very complex. Malabsorption can be caused by stomach and small intestine diseases, or by liver, gallbladder, and pancreas diseases.

4. Endocrine diseases: Many endocrine diseases are accompanied by symptoms of diarrhea, such as hyperthyroidism, diabetes, hypoparathyroidism and medullary thyroid tumor, adrenocortical insufficiency, pancreatic cholera syndrome, WDHA syndrome, watery diarrhea-hypokalemia-achlorhydria syndrome or vasoactive intestinal polypeptide tumor, gastrinoma.

5. Tumor diseases: gastrointestinal malignant lymphoma, carcinoid syndrome, colon cancer, intestinal adenomatous polyps or polyposis.

6. Gastrointestinal functional disorders: Irritable bowel syndrome includes mucous colitis, irritable colon or allergic colitis.

7. Other factors: intestinal flora imbalance and uremia.
