An estimated 32,000 in Scotland are unknowingly living with with an undiagnosed autoimmune disease that can cause serious consequences if left untreated.
Coeliac disease is a autoimmune condition affecting 1 in 100 people yet only 41% of Scots are medically diagnosed. When people with it eat gluten - a protein found in wheat, barley and rye - their body attacks its own tissues.
Now Scots are being urged to know the symptoms of the disease by charity Coeliac UK so they can get tested. One of the challenges is that symptoms can be different for everyone, ranging from gut issues to neurological complications.
And some people are more prone to others.People with type 1 diabetes are on average six times more likely to have coeliac disease compared with the general population.
