Some things to try would be the same things that are good for stomach ulcers:
Bananas. Eat at least three bananas a day. These fruits contain an antibacterial substance that may inhibit the growth of ulcer-causing H. pylori. And studies show that animals fed bananas have a thicker stomach wall and greater mucus production in the stomach, which helps build a better barrier between digestive acids and the lining of the stomach. Eating plantains is also helpful.
Just wanted to clarify that the studies I have seen for bananas treating ulcers were using plantain bananas, not the common yellow banana.
