Red and white predominantly white gastric sinus is most often considered to be atrophic gastritis, which may recover with aggressive treatment if the condition is mild. When there is inflammation at the gastric sinus, gastroscopy usually reveals red and white changes, usually suggesting the presence of chronic gastritis. If the red color is predominant, it is mostly chronic non-atrophic gastritis; if the white color is predominant, it is mostly chronic atrophic gastritis. Chronic atrophic gastritis is a disease caused by repeated damage to the gastric mucosal epithelium due to Helicobacter pylori infection, duodenal reflux and other factors, resulting in atrophy of the intrinsic glands, with or without intestinal metaplasia. Patients may manifest symptoms such as abdominal pain and distension, acid reflux belching (burping), and loss of appetite. If the patient’s condition is mild, it is possible to recover after active treatment, such as taking acid-suppressing drugs such as omeprazole, gastric mucosa-protecting drugs such as colloidal bismuth, prokinetic drugs such as mosapride, and eradication of Helicobacter pylori. However, if the treatment is not timely, the condition is more serious, and even when changes such as intestinal epithelial hyperplasia occur, it is difficult to recover completely. When the patient examination found that the gastric sinus red-white to white predominantly, it is recommended that timely medical treatment, and receive treatment, drugs need to be taken in strict accordance with the doctor’s instructions, not self-medication, so as not to delay or even aggravate the condition.
