Why Do I Have Constipation, Bloating Or Diarrhea Ever Since Gallbladder Removal? Why Does Biopsy Show Sensitivity To Gluten?

I have continuous abdominal bloating with eating and without. It gets so tight my chest feels heavy. There s a lot of discomfort up high up under my ribs especially. I have had my gall bladder removed last yr. I have constipation and now diarrhea after the gall bladder removed. I had a biopsy that showed sensitivity to gluten but I ve been gluten free as far as I know and been trying, for 4 months, no changes. I ve had ct scans, stomach xrays, cat scan, bowel series, and stomach dumping test. Other than mild gastroparesis, my doc wants to say it s IBS. I had to quit my job and I barely function. I have female problems such as pcos and I had a couple endometriosis spots fixed. Is there some how hormones are playing a part while tests come up negative?
