Check out http://www.theglutenfile.com/ for info on the different kinds of problems with wheat/gluten. There can be allergy (immediate type or delayed type), sensitivity (non-Celiac, but may be immune reactivity of a different type than Celiac), intolerance (insufficient digestive enzymes - usually this is a pancreas issue), or Celiac (autoimmune injury to small intestine caused by gluten).
Unfortunately, people - doctors and others - intermix all the above terms and that makes it really confusing for everyone.
