In general, treatment of enteritis with antibiotics is recommended for a maximum of ten days. Routinely, enteritis can be cured in about a week, so try not to exceed ten days. If the symptoms of enteritis do not improve significantly in more than ten days, or if the symptoms gradually worsen, it is recommended to stop the antibiotics in time, do the relevant bacterial culture, or drug sensitivity test, take the choice of effective antibiotics or give some antiviral treatment. At the same time, it is necessary to improve the relevant examination to clarify the type of enteritis. If it is due to immune system diseases, such as ulcerative colitis, it is recommended to actively give immunosuppressant or hormonal treatment, or you can also use para-aminosalicylic acid. If it is radiation enteritis, active symptomatic management and standardized anti-tumor therapy are recommended. If it is viral enteritis, give antiviral treatment.
