Most patients with gallstones have no obvious symptoms. Some patients may present with recurrent right upper abdominal vague pain, which is caused by inflammation caused by the stones. Others will experience colic, which is produced by stone triggered bile duct spasms. Stomach pain in patients with gallstones may be caused by the spread of pain, mistaken for stomach pain, or it may be caused by the occurrence of bile reflux gastritis, stomach diseases, etc. Attention should be paid to differential diagnosis.1. Acute attack of gallstones: At this time, symptoms of epigastric boredom and distension will appear, which in many cases are similar to the location and nature of stomach pain, and patients may mistake the symptoms as being caused by stomach symptoms. Generally speaking, the pain symptoms of gallstones will be slightly to the right, while the pain symptoms of the stomach will be slightly to the left, but not absolutely, and may be confused when there is pain spreading; 2. Bile reflux gastritis: some patients with gallstones will develop bile reflux gastritis, because the pylorus of the stomach is relaxed due to poor bile excretion, which can easily cause bile reflux from the duodenum into the stomach and cause gastric damage leading to gastritis, and in severe cases In severe cases, gastric ulcers may occur, causing symptoms related to the stomach. In this case, further treatment for gallstones is needed to reduce stomach pain; 3. Stomach diseases: Many patients with gallstones themselves have H. pylori infection in the stomach, gastritis, gastric ulcers, etc., and also have symptoms of stomach pain, not caused by gallstones. At this time, patients need further examination of gastroscopy, Helicobacter, etc., to rule out any abnormalities in the stomach.
