What are the symptoms of chronic gastritis?

The main symptoms of chronic gastroenteritis include: 1. Gastrointestinal symptoms: Characterized by recurrent abdominal pain, bloating, nausea, vomiting, and diarrhea. The severity of diarrhea varies, ranging from several bowel movements per day to dozens, and some patients may experience nocturnal diarrhea or postprandial diarrhea. 2. Changes in appetite: Loss of appetite, possibly accompanied by indigestion symptoms such as postprandial fullness and acid reflux. 3. Systemic symptoms: Long-term illness may lead to chronic wasting symptoms such as weight loss and anemia. Some patients may also experience night sweats and palpitations due to malnutrition. 4. Specific symptoms: For patients with chronic gastritis, especially chronic atrophic gastritis, significant epigastric pain may occur, often accompanied by bleeding manifestations such as hematemesis and melena.
