Ah, I think I could be in the same boat. Increasing metabolism is the way to go then. You could take stuff to help the food digest quicker and also something to help increase bile output?Vegetable fiber is in gel form...? Most vegetables even well cooked give me constipation, because they feed bacteria even low fodmap vegetables. I find only cucumbers safe. Psyllium husk don't feed bacteria. Carrot is also good but doesn't work for constipation like gel from psyllium for me. Sibo is due to low metabolism, low stomach acid, lack of bile. It's systemic. You can't treat SIBO be just taking some pills or what.
