Problem:
1. Can you please explain what stomach ulcers are, how they are formed and any other detail regarding them.
2. What is GERD? what does it effect, how does it affect us, so maybe the cause and the treatment would be really helpful. Thank you guys so much for your help.
3. They don't have to be an essay or anything, just small brief descriptions, and feel free to link any web pages you think I might find useful.
