Chronic non-atrophic gastritis, also known as superficial gastritis, is a form of chronic gastritis, a chronic inflammation of the gastric mucosa caused by a variety of etiologies. Erosion is a chronic inflammation of the gastric mucosa accompanied by superficial necrotic defects that are not deeper than the mucosal muscle layer. The clinical presentation lacks specificity and some patients are asymptomatic. In severe cases, epigastric pain may be present, and most patients with chronic superficial gastritis present with this symptom. The epigastric pain is mostly irregular and not related to diet. The pain is usually diffuse upper abdominal burning pain, vague pain, and distension. The symptoms are often aggravated by eating cold, hard, spicy and other irritating foods, and a few are related to climate change. Patients with chronic superficial gastritis tend to have abdominal distension, often due to retained food in the stomach, delayed emptying, and indigestion. Acute onset patients are often accompanied by gastric mucosal erosion and bleeding, which is seen as vomiting red liquid and coffee-like stools. In addition, symptoms such as loss of appetite, acid reflux, nausea, vomiting, weakness, constipation or diarrhea may also occur. Therefore, patients with chronic non-atrophic gastritis with erosion do not necessarily have obvious symptoms, but if the above symptoms appear, they should go to the hospital for a clear diagnosis in a timely manner and actively standardize treatment under the guidance of a doctor to avoid delaying the disease.
