Antibiotic-associated diarrhea is generally associated with dysbiosis of the intestinal flora and requires appropriate antibiotic discontinuation and pharmacological treatment. The common reason for this is that patients take antibiotics for a long time, which leads to the destruction of a large number of normal flora in the gastrointestinal tract, thus causing harmful bacteria to proliferate abnormally and proliferate, resulting in dysbiosis of the intestinal flora and causing diarrhea. The treatment of antibiotic-related diarrhea should be carried out under the guidance of a professional doctor. 1. adjust antibiotics: the type of antibiotics and the dose of antibiotics need to be adjusted early, and antibiotics with less impact on the gastrointestinal tract can be replaced for treatment. 2. regulate the gastrointestinal flora: active probiotics such as bifidobacterium, lactobacillus, and triptans can be made to regulate the gastrointestinal flora and improve diarrhea symptoms. 3.Stop diarrhea: you can also use montelukast to relieve diarrhea symptoms; 4.Rehydration: if the diarrhea is serious, you also need to rehydrate the patient to balance the body’s water and electrolytes. Precautions antibiotics should be used with caution to avoid abuse, which may cause diarrhea and even lead to the development of drug resistance of bacteria, thus forming drug-resistant strains, making treatment more difficult and prolonging the treatment period.
