So I am new to this community, so if I babble or write on the wrong blog-please chalk it up to that 
 I was diagnosed last April (after years of symptoms and dumb doctors) and went on a gluten-free diet immediately afterwards.  But
around November some of my symptoms started to come back, so I kept a food journal and went to my GI and had some blood work and a lactose intolerance test performed.  Those tests came back normal, and just as sudden as the symptoms came on-they left.  Now they are back, and it doesn’t matter what I eat: a banana, gluten-free dinner that is home made, yogurt, etc. I am miserable! My GI said that if that happened that she would do another endoscopy to see what is going on.  Is there anything else I should be thinking of?  I heard that leaky gut happens, or sensitivity to other foods..... I am kind of at a loss here.
