I've been having fatigue, constipation, belching, and getting full fast when i eat. my gi doc says to just take probiotics. does that make sense?

Abd, bowel symptoms: Well you can get full easily if you are contipated, but you are also 39 yo and unfortunately we are seeing colon cancer in younger pts.If you have a change in bowel habits, fatique, and belching you could have a number of things: peptic ulcer which is bleeding, or colon/stomach cancer.Best to have your primary md draw some blood to macke sure not anemic and get scoped both upper and lower gi.
