Many people who have lactose intolerance have CD - in this study about 25%. Not everyone with lactose intolerance have CD and not everyone with CD have lactose intolerance. As Al said, if the tips of the villi are damaged enough, there will be a deficiency in lactase. Hopefully you daughter will be diagnosed before this much damage is done. I hope that multiple biopsies were taken and that the pathologist knows to look for subtle signs of CD.

Is there CD in the family? Were your DD's blood tests positive? Which tests were run?

Hope the EGD went smoothly for your daughter. How is she feeling?
