How do i know what caused my ulcers? i have scattered ulcers and erosions, erythema, congestion in the whole stomach and the doctors don't know why....

Keep seeing dr: Sometimes we dont find the exact answers to what caused problem. With ulcers-most common cause is a bacteria called h. Pylori. This can be tested for best on biopsy from the ulcer or near it- but can also be found in stool & blood & on breath test. People who take a lot of inflammation meds like aspirin, goody, advil (ibuprofen) or steroids can get this. There is also a syndrome called zollinber ellison.
