Helicobacter pylori was identified by a friend of my husband and mine, Barry Marshal who works with my husband at the University of Western Australia. He got a Nobel Prize for this. When it comes back positive you should be put on a particular anti biotic which will kill it. It can make the stomach quite inflamed, ulcers, vomiting , and diarear. It is very easy to get rid of. Many people have this and don't know. It is very good that you were tested for it. I would have gone for the ice cream too as it can be responsible for really not feeling well etc. good luck!
For every dark cloud there is a silver lining!
