The infection rate of Helicobacter pylori in our country has already exceeded 50%, and Helicobacter pylori has been confirmed as the main cause of chronic gastritis, peptic ulcers, and even gastric cancer. If Helicobacter pylori tests positive and is accompanied by symptoms or diseases of the digestive system, eradication treatment for Helicobacter pylori is necessary. The medication involves a proton pump inhibitor, two types of antibiotics, and a bismuth agent, with a treatment period of 14 days. After the 14-day treatment, the medication should be discontinued for a month before rechecking with a carbon-14 breath test to confirm whether Helicobacter pylori has turned negative. If it has turned negative, it indicates that the eradication treatment of Helicobacter pylori is successful. After infection with Helicobacter pylori, a diet easy to digest is recommended.
