<<Disclaimer: Verify this information before applying it to your situation.>> My son was biopsy diagnosed last January. My husband, daughters and myself all had blood tests and all were negative. I have suffered from unexplained nauseau, diarehha and dizzyness for as long as I can remember. I finally decided to go GF and have felt great ever since. The few times I've "cheated" I am sick within hours. Has this happened to anyone else? Should I see a GI about a biopsy? My family practice doctor is clueless about Celiac....he didn't even know how to order my original blood tests! Any feedback is greatly appreciated! Cindy
