Flat erosive gastro-sinusitis is not difficult to treat, its treatment in addition to dietary modification, but also need to carry out causative treatment as well as symptomatic treatment. 1. Dietary regulation: patients are advised to have fewer meals for several times, avoid cold and irritating food, pay attention to less crude fiber in the diet, avoid mechanical stimulation, and also pay attention to consume easy-to-digest food in order to reduce the burden on the stomach. 2. Allopathic treatment: Hp infection related patients need to be treated in time, and the currently advocated combination program is the quadruple program containing bismuth, i.e., a proton pump inhibitor combined with the use of two antibiotics and a bismuth agent. 3. Symptomatic treatment: Antacids, such as ranitidine and famotidine, can be used to moderately neutralize or inhibit gastric acid secretion. To relieve symptoms such as bloating caused by insufficient motility or insufficient digestive enzymes, gastric stimulants or enzyme preparations can also be used. As well as gastric mucosal protectants such as bismuth potassium citrate and colloidal bismuth pectin help to alleviate symptoms such as acid reflux as well as abdominal pain. If the patient is not feeling well, he should not take medication without authorization, and needs to go to the hospital in time, under the guidance of the doctor for standardized treatment and medication, so as not to aggravate the condition.
