What is the difference between the symptoms of gastritis and gastric ulcer?

The differences in symptoms between gastritis and gastric ulcer are mainly reflected in the following aspects: 1. **Characteristics of pain**: Gastritis pain is often dull and nonspecific, without a clear pattern, and may be accompanied by postprandial discomfort; gastric ulcer pain, however, is characterized by periodicity and rhythm, commonly occurring half an hour to one hour after meals. The pain is usually described as dull, distended, or burning, and may be relieved when the stomach is empty. 2. **Associated symptoms**: Patients with gastritis frequently experience symptoms such as nausea, vomiting, loss of appetite, and indigestion. In addition to these symptoms, patients with gastric ulcers may also suffer from acid regurgitation, heartburn, belching, and hiccups. In severe cases, symptoms of gastrointestinal bleeding such as hematemesis (vomiting blood) and melena (black tarry stools) may occur. 3. **Disease course and impact**: Gastritis generally has a relatively short disease course and fewer complications. Gastric ulcers, on the other hand, are chronic conditions that can last for several years, tend to recur easily, and may lead to serious complications such as gastrointestinal bleeding and gastric perforation.
