Generally, H. pylori does not cause wasting, unless the stomach disease caused by H. pylori infection shows obvious clinical symptoms, such as making the patient suffer from loss of appetite, poor appetite, abdominal pain, abdominal distension, etc. It is possible that the wasting may occur due to eating less and not being able to keep up with nutrition. For people with wasting, it is recommended to also exclude other wasting diseases, such as tuberculosis and malignant tumors. It is recommended that you need to visit a hospital and cooperate with your doctor to improve the relevant tests to help clarify the diagnosis, and if necessary, you need to cooperate with your doctor to use medication. If H. pylori infection does exist, H. pylori eradication therapy also needs to be given under the guidance of a gastroenterologist as appropriate. The current recommendation is a quadruple therapy, PPI plus bismuth, plus two antibiotics, with specific medications and a course of treatment requiring consultation with a specialist.
