The difference between gastric ulcer and gastritis pain is as follows: abdominal pain symptoms of acute gastritis, often with acute onset and mostly triggering factors, patients will show epigastric pain, epigastric distension, nausea, vomiting, and abdominal pain symptoms can be significantly relieved after removing the triggering factors. In contrast, most patients with chronic gastritis have no abdominal pain symptoms, and those with symptoms show indigestion symptoms such as vague pain or discomfort in the upper abdomen, epigastric distention, early satiety, belching, nausea, and acid reflux. In contrast, abdominal pain in gastric ulcer is characterized by a chronic process of recurrent, regular, periodic epigastric pain, typically characterized by pain after meals, which can be relieved by hunger, and also by taking acid-suppressing drugs. An electronic gastroscopy can clearly distinguish between gastric ulcer and gastritis.
