Hi doctor! May I ask: I have had a breath test and have a gastric HP infection, but I can't do an endoscopy? If I do not have a gastroscopy, will the doctor prescribe medication? In addition, I want to ask if I want to buy a prescription, can I be prescribed by a doctor when only the results are by breath test? Currently, my stomach is normal, no pain and sometimes reflux. Ask your doctor for advice and answers. I sincerely thank!
