New research from Coeliac UK shows diagnosis of the autoimmune disease, coeliac disease, which affects 1 in 100 people, has risen in the UK from 24% in 2011 to 30% in 2015.
 
The research, commissioned by the charity, from the University of Nottingham, searched UK patient records up to and including 2015 for clinical diagnoses of coeliac disease and dermatitis herpetiformis (the skin manifestation of coeliac disease).
 
The research showed that although diagnosis rose by a quarter in four years (2011-2015), alarmingly the rate of diagnosis was slowing significantly, resulting in around half a million people in the UK still living with undiagnosed coeliac disease. 
 
It also highlighted that 1 in 4 adults over 18 years diagnosed with coeliac disease had previously been misdiagnosed with Irritable Bowel Syndrome (IBS), the same percentage that had been reported in research from 2013. 
 
Sarah Sleet, chief executive of Coeliac UK said: “It’s fantastic that the research shows that around 45,000 people were diagnosed between 2011 and 2015. But with half a million people in the UK still without a diagnosis we’ve got a long way to go.

"The fact that testing for the condition is slowing and nothing has changed in people being diagnosed with IBS before being tested for coeliac disease, suggests the NHS is failing to address the mountain of underdiagnoses. We know this is even more urgent today as recent research is uncovering some symptoms of coeliac disease, specifically neurological ones that cannot be reversed without an early diagnosis.”
 
It still takes 13 years on average for a person with coeliac disease to be diagnosed.
 
The NICE guidelines for coeliac disease and IBS recommend that anyone presenting with IBS symptoms should be screened first for coeliac disease.
 
"It is essential that people with chronic gut conditions - whether that's coeliac disease or IBS - get an accurate diagnosis as quickly as possible. Having the right tests allows healthcare practitioners to put the right treatment in place and patients can learn how to best manage their condition," said Alison Reid CEO The IBS Network.
 
“The blood test for coeliac disease is relatively quick and cheap and we urge anyone that has ongoing symptoms to visit their GP and request to be screened for coeliac disease. Next year we will be launching a campaign targeting the medical profession to encourage them to consider if their patients could be suffering with undiagnosed coeliac disease or have been misdiagnosed with IBS and ensure that they do not to remove gluten from their diet prior to testing as this could lead to a false negative result,” continued Sleet.
 
Although many people present with a range of symptoms including those that are gut related, other symptoms include mouth ulcers, anaemia, repeated miscarriages and neurological problems.
