Starvation gastroparesis, as the name implies, hurts when hungry, and there is also acid reflux, heartburn, nausea, abdominal fullness, and possibly nighttime pain or dispersion to the back. The patient will have pain when hungry, but will be fine when full, see if there is discomfort in the upper abdomen, indigestion or if there is black stool at the same time. If such symptoms are diagnosed as duodenal bulb ulcer, it is recommended to do H. pylori test and gastroscopy because most duodenal bulb ulcer is related to H. pylori infection. If such symptoms are diagnosed by gastroscopy and the ulcer is clearly a duodenal bulb ulcer, anti-H. pylori treatment and mucosal protection for acid suppression will be done. If you find that your stomach hurts when you are hungry and relieved when you are full, you must come to the hospital for gastroscopy and related tests.
