Helicobactor pylori is the bacteria that is one of the causes of ulcers in the stomach. If you are getting treatment with the triple therapy, then you should be OK, but if you are one of the few unlucky ones then go back to your GP and tell him you are getting no relief, he will send you back to the hospital for a follow up Gastroscopy, if this proves the bacteria has not cleared up then you may be put on further treatment, it could be more of the triple therapy or something else.
