There is no clear statistics to show how long colitis can live, standardized treatment of colitis patients can survive for a long time or even does not affect the survival period, while non-standardized treatment of colitis patients in serious cases may even sepsis, cancer and other serious complications, the survival period can be greatly shortened. Colitis can include inflammatory bowel disease, infectious enteritis, ischemic enteritis, etc. Inflammatory bowel disease can be treated with drugs such as mesalazine and salicylazosulfapyridine as prescribed by the doctor; Infectious enteritis, such as bacillary dysentery, can be treated with antibiotics such as azithromycin and levofloxacin, etc. After standardized treatment of patients with colitis, they can even survive without any impact on survival period and achieve long-term survival. However, for patients with colitis who are not treated in a standardized manner, the original colitis can gradually develop and induce serious complications, for example, bacillary dysentery can develop into shigella sepsis, inflammatory bowel disease may be complicated by intestinal perforation or intestinal hemorrhage, etc. Part of the colitis may also develop into cancer, and all of the above complications are more serious, and the patient’s survival period will be greatly shortened. Therefore, patients suffering from colitis should standardize their treatment under the guidance of a doctor.
