When infected with Helicobacter pylori, it will not directly cause the body to experience wasting, but if there is no effective intervention over a long period of time, it may affect the digestive function, or even induce cancerous changes, and there is a possibility that wasting symptoms may occur. Most people do not have any conscious symptoms after being infected with H. pylori, while a small number of patients may experience digestive symptoms such as acid reflux, nausea, bloating and anorexia, which do not directly cause weight loss. If H. pylori infection is not treated in time, it may increase the chances of having gastric diseases and affect the digestive function, which may result in malnutrition and lead to wasting. In addition, H. pylori infection may also induce malignant lesions in the stomach, which is also a wasting disease, causing patients to experience symptoms of wasting. Therefore, after being infected with H. pylori, it is recommended that patients go to the hospital as soon as possible and under the guidance of the doctor for treatment.
