Gastric H. pylori positivity is usually treated with quadruple therapy, which is a combination of proton pump inhibitors, bismuth and two antibiotics to eradicate H. pylori. 1. Proton pump inhibitors: drugs such as omeprazole. Omeprazole has the effect of inhibiting the secretion of gastric acid and can relieve stomach pain caused by excessive secretion of gastric acid. However, there may be adverse reactions such as rash, itching, nausea and diarrhea after taking it. 2. Bismuth: Bismuth potassium citrate is a commonly used bismuth agent, which has the function of repairing the gastric mucosa, and can relieve stomach pain, heartburn and acid reflux after taking it, but there may be adverse reactions such as nausea and constipation. 3. Antibiotics: Amoxicillin and clarithromycin are usually used in the treatment of H. pylori. Amoxicillin and clarithromycin both have antibacterial effects, and the combination of the two can enhance the bactericidal effect on H. pylori, but there may be abdominal pain, diarrhea, nausea and other adverse reactions after taking them. If you are diagnosed with positive H. pylori, it is recommended that you consult a doctor in time for targeted treatment under the guidance of the doctor. The medication should be taken under the guidance of a physician.
