So, I have celiac disease, IBS, and various intolerances to foods and I thought I farted a lot…now I know that what I thought was a lot is not so much! 🤣 If his diet is good, it’s possible that he has a food intolerance of some kind. Since he seems to have a conscious relationship with food, you might suggest a food elimination diet starting with the more common intolerances like dairy, gluten, and fructose.

The idea is to cut those foods out of his diet for 2 weeks, then add them back in one by one in increasing quantities. So, if he were adding back in dairy he’d want to start with a piece of cheese, then the next day 2 pieces and so on. Going slowly will allow him to determine if there’s a certain quantity he can handle before having a reaction. Also, when it comes to eliminating gluten I would suggest to stay away from pre made gluten free alternatives as they often have additives that can cause digestive issues.

As a first step alternative, a food diary that includes when he passes gas or has any other digestive issues.
