The good news is that this condition is totally curable, the sole treatment being the gluten free diet, and, perhaps initial nutrient supplementation. It has to be a strict gluten free diet for life. It is something the patient will never "grow out of". Once gluten is eliminated from the diet, the villi start to regenerate and grow, and their task of absorbing nutrients, and preventing the release of harmful peptides into the bloodstream, can once again commence.

The enzymes, particularly the lactase, maltase and sucrase enzymes at the tips of the villi become usable again and can begin to perform their task of breaking down and digesting food again, so that lactose intolerance will gradually subside.

Healing of the tissue starts to take place very quickly.  If one were to "cheat" on the diet and start eating gluten-containing foods again, tissue damage begins to occur once more, regardless of the absence of outward symptoms. It can then take up to a period of as long as two years before major symptoms become noticeable again. For many Coeliacs, however, the symptoms are immediate.

The Dermatitis Herpetiformis patients can be further diagnosed by examining the deposits of immune components (IgA) in biopsies of unaffected skin (between the blisters). Their treatment would be a course of tablets or medication such as Dapsone prescribed by a dermatologist, which takes the itch away, plus a strict gluten-free diet for life, as well as the restriction of iodine in the diet which exacerbates the itch.
