Coeliac disease (CD) is an auto-immune disease caused by intolerance to gluten, found in wheat, rye and barley. Around 700,000 people in the UK have it although seven in every eight are presently undiagnosed and ignorant of their condition. Increased awareness of the disease, ongoing campaigning from the charity Coeliac UK and amendments to NICE guidelines for the diagnosis of both IBS and CD, have all meant that more and more of the missing coeliac patients are being picked up. Coeliac UK welcome over 100 new members a month. Mild CD in particular is more common than previously thought. Coeliac Disease: What you need to know addresses the needs of those who suspect they may have CD, or who are newly diagnosed, both of whom are increasing in number. It aims to support and advise those with the disease, as well as those who are parents of coeliac children or who care for adults with CD.
