The difference between atopic enteritis and non-atopic enteritis is whether there is a clear cause. Generally, atopic enteritis has a clear cause, such as bacterial enteritis, pseudomembranous enteritis, viral enteritis, and radiation enteritis, which are all types of enteritis with a clear cause. Non-specific enteritis has no clear cause and is considered to be caused by diseases of the immune system, such as ulcerative colitis, Crohn’s disease, etc. Therefore, the biggest difference between the two is whether or not there is a clear cause. The treatment is also relatively different, atopic enteritis is the choice of targeted drugs. In the case of bacterial enteritis, sensitive antibiotics are selected for treatment according to the drug sensitivity results, and antiviral treatment is given for viral enteritis. In the case of pseudomembranous enteritis, antifungal drugs are selected for treatment. The non-specific enteritis, generally due to the immune system disease caused by unexplained enteritis, it is recommended to give hormones or immune preparations, but also can choose some p-aminosalicylic acid and other drugs for treatment.
