With atrophic gastritis and proctitis, it is necessary to find out the cause of the disease with the help of professional doctors and combine with the patient’s own situation to relieve the condition through medication, surgery, dietary regulation, psychological relief and other methods. 1. Atrophic gastritis: eliminating the cause of the disease is the main focus, for example, most of them are due to Helicobacter pylori, which can be combined with proton pump inhibitors, bismuth, and two antibiotics to use quadruple therapy to cure the disease, such as omeprazole, bismuth pectin, furazolidone, and clarithromycin. Urea carbon 14 or 13 review is needed after two weeks of treatment and 1 month off medication to see if H. pylori is eradicated. Regular review of gastroscopy, if there is a severe heterogeneous hyperplasia, endoscopic surgical treatment is also required. 2. Inflammation of the rectum: a healthy diet and a well-adjusted state of mind are required, and treatment is tailored to the cause of the disease. For example, ulcerative proctitis, mild cases can be treated with mesalazine combined with glucocorticoids; severe cases can be relieved with infliximab. In severe cases, infliximab can be used to alleviate the condition. For surgery, total colorectal resection with ileal storage bag and anal anastomosis can be used. Drugs and surgery are both risky, so you need to talk to your doctor before treatment and take the medication as prescribed.
