Since the beginning of summer, Mr. Wang, who lives in the East District, had diarrhea, so he went to the pharmacy and bought several boxes of haloperidol capsules to eat. After half a month of eating, not only did it not work, but it became heavier and heavier, so he rushed to the outpatient clinic to see a doctor. After the examination, he was suffering from antibiotic-associated enteritis, which was quickly cured by the treatment. Antibiotic-associated enteritis is a kind of intestinal disease formed by the long-term use of antibiotics leading to the dysbiosis of the intestinal flora. In fact, there are a large number of beneficial bacteria in people’s gastrointestinal tract, such as lactobacilli and bifidobacteria. Under normal circumstances, they restrain each other, coexist peacefully, in a dynamic balance, thus maintaining the normal digestive function of people. Once this balance is disrupted, it will make the human body sick with digestive disorders, such as diarrhea, bloating and other symptoms. The long-term use of antibiotics or irregular use of antibiotics will kill the beneficial bacteria while killing the pathogenic bacteria, thus breaking this dynamic balance and causing a series of gastrointestinal symptoms, hence the term antibiotic-associated enteritis. If you have obvious diarrhea symptoms in summer and autumn, you must first go to the hospital to check the stool and blood routine, if necessary, stool bacterial culture, to find out whether it is infectious enteritis or dysfunctional diarrhea, do not buy a few boxes of anti-inflammatory drugs and anti-diarrheal drugs at the pharmacy on your own and then everything will be fine, so as not to treat the more serious. If it is infectious gastroenteritis, anti-infection treatment should be carried out under the guidance of a doctor. If it is dysbiosis, all antibiotics must be stopped and drugs to regulate dysbiosis, such as Lizhu Enteral, Pepcid, and Rectify, etc., should be used as soon as possible, and electrolytes and water should be replenished if necessary, and diet should be adjusted at the same time.
