HP stands for Helicobacter pylori, which is a normal bacterium that lives in the stomach. Current research has found that H. pylori is not the cause of gastric cancer or gastric ulcers and is a normal flora that does not cause disease when pathogenic levels are not reached. Clinical monitoring methods for H. pylori include a carbon 13 or carbon 14 breath test, which does not require treatment if it is less than 100 dpm. If it exceeds 100 dpm, anti-H. pylori medication is required. Gastric triple or quadruple drugs are usually used clinically. If H. pylori is negative, this means that H. pylori is undetected and clinically normal. If the test is positive, symptomatic treatment with medications of your choice, such as omeprazole, clarithromycin and amoxicillin, is required under the guidance of your doctor.
