Does weight loss surgery cause bad breath?
Weight loss and the breakdown of fats cause the formation of ketones which are volatile and are partially exhaled. The odor however is not unpleasant and has been likened to that of Juicy Fruit chewing gum. It is important however to maintain normal dental hygiene and to brush your teeth even when taking only a liquid diet; otherwise, bacteria accumulate on the tongue and between the teeth and can cause bad breath.
