Diarrhea the day after drinking is most likely related to unclean diet on the first day, but it does not exclude diarrhea caused by alcohol and other stimulation of the patient’s gastrointestinal tract. At this time, it is recommended to use drugs that regulate the intestinal flora, i.e. probiotics, such as rectified intestinal raw, Gold Diflucan and other drugs, which can improve the intestinal microenvironment, reduce harmful bacteria, increase the number of probiotics and improve the symptoms of diarrhea. It is also important to replenish water in time, especially light salt water, etc., which can prevent dehydration caused by diarrhea. Waiting for about 12 hours after drinking alcohol, you can consider treatment with antibacterial drugs, such as the use of fluoroquinolone antibiotics (norfloxacin), which can quickly destroy pathogenic microorganisms and solve the inflammation problem. Recently, you should eat a light, easy-to-digest diet, quit smoking and drinking, avoid spicy and stimulating, cold food, and pay more attention to rest.
