<<Disclaimer: Verify this information before applying it to your situation.>> Hello everyone, I just had my results from the biopsy and they said it was negative to celiac but positive to reflux. I also had blood tests that were negative but I was on a gluten free diet when taken. My question is how long do you need to eat gluten in order to have a positive test. I did it for about a month and felt terrible with gas, bloating, constipation, and joint pain with terrible fatigue. (I am the one with a great aunt that was diagnosed with celiac later on in her life) I have no signs of reflux - no heartburn or stomach pain. I started a gluten free diet and find when I have small amounts of hidden glutens my symptoms return with gas bloating and then with bone pain in hands and feet the next day. I have fibromyalgia but refuse to accept it especailly since I am only 28. Does anyone else know of any similar diseases to celiac???? I never had any allergy tests done. Is that my next step? I feel pretty stupid now.......I do not know which direction to turn. I have an appoinment on Tuesday with the gastro. Dr. Do I ask for a second opinion on the slides? Or just try the diet for a while and see if all symptons go away. Thanks
