Currently, the infection rate of Helicobacter pylori in our country has exceeded 50%. The carbon-14 breath test can be used to detect the presence of Helicobacter pylori infection. If the infection is positive and is accompanied by some symptoms or diseases of the digestive system, eradication treatment for Helicobacter pylori is required.

The treatment regimen consists of a proton pump inhibitor, two antibiotics, and a bismuth agent, lasting for 14 days. After stopping the medication for a month, the carbon-14 breath test is rechecked to confirm whether the Helicobacter pylori has been converted to negative. If the conversion is negative, it indicates that the eradication treatment for Helicobacter pylori was successful. Helicobacter pylori has been confirmed as the main cause of chronic gastritis, peptic ulcer, and gastric cancer, thus if the Helicobacter pylori infection is positive, eradication treatment is necessary.
