Hi Ben Yehudah, I had an endoscopy. All the doctor said was to avoid spicy food. Luckily I don't have the h. pylori bacteria.
And to answer Fibrogirl's question, I'm not Ashenazi. But I would rather not avoid all dairy. I did so last year when I lost some weight, and as a result, my nails are not in the best shape. They sometimes split. But I think I might just see a dietician.
