Diagnostic criteria for infectious diarrhea

Diarrhea is a common disease in daily life. Eating unclean food, catching a cold, gastrointestinal cold, etc. may cause diarrhea. Once diarrhea occurs, the most worrying thing is dehydration. Therefore, the most important thing for diarrhea is not to let the body show symptoms of dehydration. The infectious diarrhea we are going to talk about today is mainly caused by bacteria, viruses, and fungi, and manifests as abdominal pain, nausea, vomiting, fever, and increased bowel movements. So how do you diagnose whether it is infectious diarrhea? Let's talk about its diagnostic criteria.

Infectious diarrhea is divided into three types: acute, persistent and chronic. Acute infectious diarrhea generally lasts less than 14 days, persistent infectious diarrhea generally lasts 14-29 days, and chronic infectious diarrhea generally lasts more than 30 days.

Diagnostic criteria for infectious diarrhea:

1. The stool contains mucus and blood. Routine stool examination of patients with infectious diarrhea may reveal mucus and blood in their stool. Red and white blood cells can be seen under a microscope.

2. The total white blood cell count and neutrophil classification increase. After a routine blood test for patients with infectious diarrhea, an increase in the total white blood cell count and neutrophil classification can be seen.

3. Hematuria, hemoglobinuria, and tubular urine. Due to viral or bacterial infection, the urine of patients with infectious diarrhea often contains hematuria, hemoglobinuria and tubular urine.

4. Increased serum fibrin degradation products. In patients with infectious diarrhea, not only does the serum fibrin degradation products increase, but also the blood BUN, CR, AST, ALT, BIL, LDH, CK, etc. may increase.

5. The total amount of unformed feces excreted per day exceeds 250 grams.

After diagnosis, if it is confirmed to be infectious diarrhea, effective measures should be taken as soon as possible for treatment, such as diet therapy, eat more fresh vegetables and fruits, eat more foods high in vitamins, eat less easily digestible foods, eat less fried and greasy foods, and drink less canned fruit juice; rehydration therapy, oral rehydration salts, drink less water; drug treatment, oral adsorbents such as montmorillonite, pectin and activated carbon, or oral probiotics, or intestinal motility inhibitors such as loperamide and phenoxylate, or proud UN champion drugs such as metronidazole, or antiviral drugs such as nitazoxanide; Chinese medicine treatment, oral berberine hydrochloride.
