There is no such thing as a serious or not serious H. pylori 230.
H. pylori 230 usually refers to a carbon-13 or carbon-14 test result of 230, a value that indicates that the patient is infected with H. pylori. A Carbon-13 or Carbon-14 test result can only indicate whether or not the person is infected with H. pylori, and the value cannot be used to determine whether or not it is serious.
H. pylori is a spiral-shaped, gram-stain-negative bacterium. Infection with H. pylori may cause a variety of diseases, such as peptic ulcer, dyspepsia, and gastric malignancy. If H. pylori infection leads to the development of gastric malignancy, it is a more serious disease.
Patients with H. pylori infection need to be treated aggressively and use communal chopsticks when eating together.
