A positive carbon 13 breath test is curable. Positive carbon 13 breath test suggests the presence of H. pylori infection in the organism, and H. pylori can be eradicated through treatment. Nowadays, the treatment of H. pylori generally adopts quadruple therapy, i.e. one proton pump inhibitor + two antibiotics + one bismuth agent, such as omeprazole + amoxicillin + metronidazole + bismuth potassium citrate. After infected with Helicobacter pylori, you should pay attention to practicing meal sharing with your family members, not sharing eating utensils such as tableware and cups, developing good living habits, washing hands before and after meals, and paying attention to food and hand hygiene. If the carbon 13 breath test is positive, you should consult a doctor for standardized treatment under the doctor’s guidance, and the carbon 13 breath test can become negative after eradicating H. pylori.
