Elevated H. pylori antibodies reflect a previous H. pylori infection, but do not indicate a current infection. If H. pylori is infected and there is discomfort, bloating, or diarrhea in the stomach, there may be inflammation in the stomach. However, not all patients with H. pylori infection are in need of treatment, and it also depends on the patient’s condition. Patients with H. pylori can be treated with drugs such as proton pump inhibitors, metronidazole, and clarithromycin. If there is a failure to carry out timely treatment, the body’s immunity will be reduced and it will lead to aggravation of gastritis and even atrophic gastritis, which can lead to cancer in serious cases. Therefore, in daily life, it is recommended to develop good eating habits, pay attention to oral hygiene, and disinfect meal utensils regularly to avoid cluster infections.
