People that have a severe imbalance of gut bacteria, let's say they have a lot less of the commensal bacteria which is making short chain fatty acids and metabolites like lactate that are feeding other good bacteria, they're feeding your gut cells. So you have less of those and you have more of the bacteria that are methane or hydrogen sulfate producing, so you get bloated, more of the more pathogenic type of bacteria. So you have this overgrowth of bad bacteria.
