Chronic gastritis, under gastroscopy, can usually be divided into two main categories: chronic non-atrophic gastritis, also known as superficial gastritis, and chronic atrophic gastritis. The primary cause is related to Helicobacter pylori infection, although there are other related factors, such as exposure to cold, poor dietary habits, medication factors, and more. As for the symptoms of gastritis, there is individual variation. It can manifest as either excessive gastric acid or poor gastric motility. Excessive gastric acid can present as upper abdominal pain, heartburn, and acid reflux burn, among others. Poor gastric motility may lead to symptoms such as nausea, vomiting, bloating in the upper abdomen, and poor appetite.
