Hello, Thanks for the query to H.C.M. Forum. Helicobacter pylori is a not contagious so need not to worry. As far as concerned about treatment it depends upon many factors and depends upon treating doctor and symptomatic relief. Usually course of 3-4 weeks is sufficient . But important thing is AVOIDANCE . If you use alcohol ,fried food ,junk food, excessive drugs, sweets, they will aggravate the condition. Consult a physician and get his opinion and treatment. Hope I have answered your question. If further any question I will help. Get well soon. Dr. HET.
