I'm 65, loose stools not everyday. Sometimes gas, bloated. Cbc, cea, schevo test all normal. Should I worry?

Annual Checks. You need to have your regular annual check ups and ask your doctor for advice. The only thing I would want to make sure is that you have had a Colonoscopic exam for Cancer screening.This is one important test.Other than that your problem does not sound serious. You should exercise daily...walking is one of the best way to keep your bowel healthy and moving normally. This will help to reduce bloati.
