Hello! - this is my first post here.
In early onset(or really any point) of AS can unexplained weight loss occur? It's not mentioned as one of the typical symptoms but I did read one article that suggested that unintentional weight loss could occur. If it did happen I would presume it was because of a secondary condition caused by AS.
I am wondering because I have a suspicion that I may have AS and began having unintentional gradual weight loss during the time of my lower back pain onset.
I have no GI symptoms but a lactulose breath test confirmed very elevated levels of hydrogen suggesting SIBO. I did test negative for the HLA marker.
Thanks for your input!
