With gut sx I usually start with digestive support and food sensitivity testing, maybe SIBO if the sx are screaming SIBO, then will progress as needed to stool, OAT etc.
But what about other non immune mediated causes of gut inflammation: is there a handy dandy chart to remind me/us of where else to look for causes of gut sx when necessary / salicylate, phenols, amines, enzyme def, food colorings, personal care products etc / , cross-overs – a list showing all the possible “others”, the foods/products they come in, and substitutes. Thanks, Lorraine
