Helicobacter pylori infection in the stomach can produce hydrogen sulfide gas with the smell of rotten eggs, causing bad breath. Generally, if Helicobacter pylori is found, it should be treated in time. Delaying the treatment may cause more serious gastric diseases such as atrophic gastritis and gastric ulcers. Moreover, after infection with Helicobacter pylori, the risk of gastric cancer may increase by 2.7 to 12 times. Because if there is no Helicobacter pylori infection, at least a considerable number of patients will not develop gastric cancer.
