Possible causes of a bitter mouth include gastrointestinal problems, liver and gallbladder diseases, oral inflammation, and damage to the nervous system.

Gastrointestinal problems: for example, gastric ulcers and duodenal ulcers are usually caused by Helicobacter pylori infection, and the urease enzyme of Helicobacter pylori can be broken down in the body to produce carbon dioxide, ammonia, etc., which in turn causes bad taste in the oral cavity and bitter mouth symptoms, resulting in a bitter taste when eating. Gastroesophageal reflux disease (GERD) patients may also experience bitter eating, which is caused by bile reflux due to the weakening of the pyloric sphincter.
2. Liver and gallbladder diseases: for example, cholecystitis, gallstones, etc., due to the poor function of the gallbladder, bile excretion is not normal, it is easy to produce a bitter feeling in the mouth, resulting in the phenomenon of eating a bitter mouth.
