The onset of gastric ulcers is not significantly related to gender. 3. mental factors The onset of both is related to mental factors, but the onset of duodenal ulcer is more closely related to mental factors; 4. blood type The incidence of duodenal ulcer disease is high in people with “O” blood type, while the onset of gastric ulcer is not related to blood type. 5. Symptoms Duodenal ulcers generally have obvious symptoms such as pain when hungry, nighttime pain, acid reflux, etc., which are relieved after eating, while gastric ulcers are not typical of the above, and secondly, the symptoms of gastric ulcers are generally heavier than those of duodenal ulcers, which are easier to control than those of gastric ulcers; 6.
