Chronic gastritis is relatively common in clinical settings and is frequently seen in the gastroenterology outpatient department. Chronic gastritis can manifest in various ways and may cause stomach pain, typically presenting as upper abdominal pain, which is generally considered pain above the navel. The nature of the pain can be bloating, colic, dull pain, or burning pain, or patients may simply experience discomfort. Of course, patients may also have other symptoms such as nausea, vomiting, dry heaving, belching, and hiccupping, but generally do not exhibit alarming symptoms such as anemia, vomiting blood, bloody stools, or fever, etc. The diagnosis of chronic gastritis generally relies on gastroscopy, which can reveal congestion, edema, and erosion of the gastric mucosa under gastroscopy, and in some cases, distinct ulcers and tumors. The treatment mainly focuses on protecting the stomach and symptomatic management, generally with good results.
