SIR - Coeliac UK is the national charity for people with coeliac disease and dermatitis herpetiformis.

We are urging your readers, in Coeliac UK Awareness Week – from May 11 to 17 – to ask “is it coeliac disease?” if they are suffering from any of these symptoms - stomach cramps, nausea, vomiting, regular bouts of diarrhoea, constipation, bloating, ongoing fatigue, anaemia, weight loss, or constant mouth ulcers.

If that is you we encourage you to visit www.isitcoeliacdisease.org.uk and take the Coeliac UK online assessment for coeliac disease symptoms and risk factors.

The assessment provides you with a result that you can take to your GP if the result indicates a need for further investigation into coeliac disease.

A lack of diagnosis means unpleasant symptoms recurring on a frequent basis which, if left untreated, can lead to serious health problems such as osteoporosis and in some cases, small bowel cancer.

It is estimated that around half a million people in UK have coeliac disease but remain untreated and undiagnosed.

The good news is that coeliac disease is treatable by switching to a strict gluten-free diet for life.

So, in this week of awareness and beyond when you notice these symptoms, be ready to ask yourself “is it coeliac disease?”.

Sarah Sleet, Chief Executive of Coeliac UK
