Suggest Treatment For H.pylori, Gas, Bloating And Loose Stools

I was diagnosed with H-pylori last year. For about (2) months, I ve been very gasy with bloating. I look like I m (9) months and ready to deliver. I am 66 years old and this condition is becoming overwhelming. I also suffer with loose stools in the morning with some moderate pain in my lower and upper stomach. Can you help or advise. Thank You
