Negative H. pylori antibodies generally means that you are not infected with H. pylori. H. pylori is a microorganism that can survive in the human stomach. Infection with H. pylori may cause a range of gastrointestinal disorders, such as gastritis, peptic ulcer, gastric cancer, and gastric mucosa-associated lymphoid tissue lymphoma. Patients usually have symptoms such as abdominal pain, bloating, loss of appetite, acid reflux and nausea. Generally speaking, a positive H. pylori antibody means that one has been infected or is infected with H. pylori, while a negative antibody generally indicates that there is no H. pylori infection, but the possibility of false negatives cannot be ruled out, and it is recommended to do the C13 and C14 breath test to clarify the cause of the symptoms mentioned above. After clarifying the cause, it is recommended to standardize the treatment under the guidance of the doctor for early recovery.
