not only does testing tell you have ulcers, but it can tell you what kind.
ulcers dont just come from
stress or lots of caffeine, they can also be from a bacterial infection, and if it is, you have to take a bunch of pills to kill the infection. also, a few of the not so common conditions im referencing (sorry, cant remember the names) cause recurring ulcers, but are not usually limited to stomach ulcers. ulcers will appear in other parts of the body, such as kidneys, adrenal glands, etc.
