I also had the Antibiotic resistant helicobacter curse; but I am now free from it, thanks to a more insightful gastro specialist who treated me with a combination of Antibiotics and BISMUTH - only available from a compound chemist.
Nasty stuff which caused severe nausea for the entire two weeks of treatment, but it was worth it.
What works on some people doesn't necessarily work on others; so don't judge the medical profession OR the natural remedies advocates on a survey on one.
Some times we need a combination of both.
