I think it would be a good idea to go for a colonoscopy.  Over the last 4 days I have had liquied diareha for 3days, bloating, uncontrollable burping and belching, loss of appetite..what should I do?
[|AI|]  Hi and welcome to Chat Doctor. These aren't usual symptoms of colon cancer or any colon disorder. It sounds like upper gastrointestinal disorder, stomach(HERD, gastritis), duodenum or gallbladder(stones). It is usually recommended to do colonoscopy after 50 age because in younger colon cancer is uncommon. But if you want to be sure you can do it, maybe some diverticulosis, polyp or inflammatory bowel disease may be discovered. Wish you good health.
