Stomach stones remain in the stomach for a long time, neither digested nor discharged, with the increase in volume, easy to complicate pyloric obstruction, gastric ulcer, erosive gastritis, and even the possibility of gastric perforation. In addition, eating on an empty stomach is also likely to lead to gastric dysfunction, especially when the above-mentioned diseases themselves, more likely to appear stomach bloating, acid reflux, nausea, epigastric distension feeling, loss of appetite and a series of symptoms. It is still recommended that after meals, it is better to eat moderately, which can reduce the direct contact with stomach acid.
