My celiac blood tests are negative. During endoscopy everything was normal but biopsy showed marsh 1 inflammation. All of this was during gluten containing diet for 22 weeks. I tested for sibo using hydrogen breath test it came out negative also. I am very severely lactose intolerant. I struggle with my mental health also. What kind of issue am I having? I am having eggs now and gluten but i don't feel well at all.
