Recent studies have shown that only about 30% of patients with diarrhea require antibiotics, and that the efficacy of various antibiotics is gradually declining. Improper use of antibiotics may have more side effects than therapeutic effects. Why can’t antibiotics be used for some infections? Diarrhea is divided into infectious and non-infectious diarrhea according to the different causes. Anti-infective drugs are applied only when it is clear that it is a bacterial infection, etc. 1. Infectious diarrhea, where various infections of the intestinal tract lead to increased intestinal exudation and secretion, and the stool contains exudates, inflammatory cells and blood. 2, non-infectious diarrhea, mainly due to increased osmotic pressure in the intestinal lumen, abnormal intestinal mucosal permeability or accelerated gastrointestinal motility. The stool is free of inflammatory cells, has high osmotic pressure and may contain undigested food. What other drugs are available for treating diarrhea besides antibiotics? Micro-ecological agents are gradually emerging, which can directly supplement the normal physiological bacteria inherent in the human intestine, regulate intestinal flora, improve the intestinal microenvironment, promote the body’s decomposition and absorption of nutrients, synthesize vitamins required by the body, stimulate the body’s immunity, inhibit potentially harmful bacteria and even pathogenic bacteria in the intestine, reduce the production and absorption of intestine-derived toxins, and reduce the burden on the liver, and can treat diarrhea caused by intestinal It can treat various symptoms caused by intestinal flora imbalance, including diarrhea. Commonly used micro-ecological preparations and their components 1, Bifidobacterium gold: 0.5 g/tablet (Bifidobacterium trituberculosis tablets).

Of course, antidiarrheal drugs and drugs to protect the gastric mucosa can also be used when necessary.
