Intestinal Metaplasia: What do you do to lower the risk of cancer?

I was diagnosed with this as well. Went in due to stomach pain, burning in my stomach, can’t eat and feeling nauseated. H-pylori is negative. Colonoscopy was normal and now Mayo tells me nothing!! What am I supposed to do just live with this pain, not being able to eat, nauseated all the time? I take pantoprazole 40mg twice a day plus Prilosec 40mg daily, I am eating tums like they are candy and my stomach is on fire. I typically eat a yogurt a 4oz cottage cheese and a protein shake and try for a small meal if I am able..that doesn’t always work out as I am nauseated most of the time. Am I just supposed to hope this gets better and they put me on Reglan 10mg four times a day thinking I had gastroparesis but no one calls me back. All the research says they can remove the areas from your stomach lining, remove a section of your stomach to relieve the symptoms but here I am reading it’s nothing to worry about??? I can’t imagine continuing with these symptoms forever. My diet has been pretty bland for the last three weeks since the symptoms have been the worst and nothing is helping!!! Thoughts???
