Helicobacter pylori is usually detected using the carbon 14 breath test, where a value higher than 300dpm is a more serious condition, and the carbon 13 breath test, where a value higher than 4.4dpm is a more serious infection. In the carbon 14 breath test, values below 100dpm are normal, and in the carbon 13 breath test, values below 4dpm are normal. Carbon 14 breath test values above 300 dpm are more serious, and with carbon 13 breath test values above 4.4 dpm the infection is more serious. There are different treatment options for different levels of H. pylori infection. When the infection is mild, dietary modification should be adopted, eating more food to nourish the stomach, and at the same time, eugenol in clove tea can inhibit the reproduction of H. pylori; when the infection is more serious, triple or quadruple therapy should be adopted to eradicate the infection. Infected with H. pylori should seek timely medical treatment under the guidance of a professional physician as soon as possible.
