What are the symptoms of chronic gastritis?

The clinical manifestations of chronic gastroenteritis mainly include: 1. **Stomach pain**: Patients often experience dull or cramping pain in the upper abdomen or around the navel, particularly worsening several hours after eating or following meals. 2. **Indigestion**: Symptoms include bloating, belching, loss of appetite, nausea, and vomiting. 3. **Intestinal symptoms**: These may include constipation or diarrhea, as well as acid reflux, which can cause heartburn and a burning sensation in the throat. 4. **Systemic symptoms**: Long-term illness may lead to anemia, fatigue, and a general feeling of weakness. These symptoms may vary as the disease progresses, affecting the patient's daily life and overall health. If the aforementioned symptoms occur, timely medical evaluation and treatment are necessary.
