I had h pylori last June, I came to know about it through endoscopy, though I had asked Dr is it contagious can it spread to my wife but he denied ..since last few months she is having continuous burping problem when she takes antacid it gives relief for short period ...I am worried she may also be infected with h pylori..she is afraid of doing endoscopy..can we do blood test for it ...she is having a lot of problem with those burps...
