After treatment for Helicobacter pylori, having more flatulence generally isn't directly related to the treatment, as the medication used includes proton pump inhibitors, antibiotics such as amoxicillin, clarithromycin, as well as bismuth citrate potassium. None of these drugs typically cause increased flatulence. If a patient experiences more flatulence after treatment, it might be due to functional dyspepsia. At this point, treating the condition with medications that regulate the gut flora, such as combined lactobacilli and Bifidobacterium triple live bacteria, might be effective. If the increased flatulence persists, it is advisable to promptly undergo a digital colonoscopy to rule out the possibility of organic intestinal diseases. (Specific medications should be used under the guidance of a doctor.)
