I don't believe so.
More specifically I have a case of dull aches in my upper stomach that flare up a few minutes after I eat something. When I have a "movement" I feel relief. My roommate thinks I have an ulcer which he has said:
a) eat more fruits and veggies (which I have been doing)
b) No more alcohol
c) no smoking
d) run run run.
I haven't drank in weeks, I haven't smoked since last March, I eat a moderate amount of greens and fruit, and I haven't found time to do jack sh*t for exercise since Winter Break.
If you think it may be an ulcer, I'd recommend getting some over the counter prilosec right away. It will reduce acid production in your stomach.. which isn't great if you don't have frequent heartburn... but is very beneficial to people with ulcers.
Just took some prilosec.
Holy hell, I feel a lot better.
That isn't to say it's completely gone but it's definitely improved.
I'm still going to see the doctor on Wednesday though (just to be safe).
Not only that, but if it is ulcers, there's a good chance that a course of antibiotics will cure it so that you don't have to keep taking the OTC junk.
