Dealing with GERD and Stomach Inflammation

Who else has GERD or stomach inflammation? Have you found anything that helps you? My family has a history of GI issues and i’m only 23, so I’m worried that my problems will turn into IBD or that i’ll get colon cancer like my grandpa. I’m doing yoga 6 days every week and trying to eat healthier by limiting junk food and cooking more. I also started avoiding dairy most of the time because it makes my stomach pain worse and increases inflammation. I need to choose a new probiotic but there’s so many out there and idk which one to try. I’m tired of the stomach pain and feeling so sluggish and tired.
