Hello, my name is Dr.Dorina Gurabardhi. I understand your concern. Infections due to viruses, bacterial infections, and parasites can cause diarrhea, nausea, vomiting, as well as excess mucus production. In the case of bacterial infection, these can include helicobacter pylori. Some advices that I can give to you are: -10 days to 2 weeks of one or two effective antibiotics, such as amoxicillin, tetracycline -Drugs that reduce the amount of acid in your stomach by blocking the tiny pumps that produce it like nexium -Bismuth subsalicylate Hope my answer was helpful, if you have any other questions I ll be glad to help, thanks!
