Chronic superficial gastritis may be characterized by upper and middle abdominal discomfort, fullness, and lack of appetite; duodenal bulbar inflammation may be characterized by epigastric pain, nausea, and vomiting. The clinical manifestations of both diseases are non-specific and difficult to distinguish from the symptoms. Most patients with chronic superficial gastritis have no obvious symptoms. Even if there are symptoms, they are mostly non-specific. They may be characterized by discomfort in the upper and middle abdomen, fullness, dull pain, burning pain, etc. They may also present with dyspeptic symptoms such as lack of appetite, belching, acid reflux and nausea. Duodenal bulbar inflammation is an inflammation that occurs in the bulb of the duodenum, which can also present with gastrointestinal symptoms such as epigastric pain, fullness, nausea, and vomiting. Therefore, the symptoms of chronic superficial gastritis and duodenal bulbitis are not very different, after the discomfort should go to the hospital in time, under the guidance of the doctor for targeted treatment.
