H. pylori eradication of gastric diseases is not always good because some gastric diseases, may be caused by other reasons. If the stomach disease is caused by H. pylori infection, such as gastric ulcer, gastric erosion, etc., it can be treated by following the doctor’s prescription with quadruple therapy, i.e., one proton pump inhibitor, one bismuth agent, and two antibiotic drugs, such as omeprazole, bismuth pectin, amoxicillin, and metronidazole, etc., and the stomach disease can usually be recovered after the eradication of H. pylori. However, stomach disorders may also be caused by other reasons, such as dietary factors or psychological factors. Simply eradicating H. pylori is not a complete cure for stomach disorders, and these triggers have to be removed. Different treatment methods are available for different stomach diseases, so it is recommended to go to the hospital in time to find out the cause of the disease and cooperate with the doctor to take targeted treatment.
