Yep - that's what it was, in my case. I experienced similar to OP. My GP ran a battery of blood tests, including celiac, bacterial infection, and parasites. I got referred to an allergist, who did an allergy panel - came up that I was allergic to certain trees (which I already knew), but nothing else out of the ordinary. The allergist brought up the possibility of lactose intolerance, and advised gradually eliminating dairy. That worked; I drastically cut back on dairy, and the GI problems/loose bowel movements totally disappeared.
Hoping you find the cause soon, OP.
