Symptoms

What does coeliac disease ‘look like’?

Coeliac disease is known as a ‘Clinical Chameleon’… it can be hard to spot!

Untreated coeliac disease can cause lots of different symptoms; some obvious, some more subtle. It can also present differently in each person, ranging from severe symptoms all the way through to ‘asymptomatic’ (having no obvious symptoms).

Importantly, there is no correlation between symptom severity and the level of damage that occurs inside the body. Even if you have no obvious symptoms, your health is still at risk if your coeliac disease remains untreated. Everybody with coeliac disease, no matter their symptoms, needs to follow a gluten-free diet.

What to look for

Symptoms can include the following – if you have any of these, you should be screened for coeliac disease:

  • icon
    Persistent gastrointestinal symptoms e.g. diarrhoea, constipation, nausea, vomiting, flatulence/gas, cramping, bloating, abdominal pain, steatorrhea (fatty, floaty poo)
  • icon
    Prolonged fatigue, weakness and lethargy
  • icon
    Iron deficiency anaemia and/or other vitamin and mineral deficiencies
  • icon
    Failure to thrive or delayed puberty in children
  • icon
    Unexplained weight loss
  • icon
    Severe or recurrent mouth ulcers
  • icon
    Skin rashes such as dermatitis herpetiformis

If your doctor has diagnosed you with any of the following, screening for coeliac disease should also be considered:

  • icon
    Irritable Bowel Syndrome
  • icon
    Early onset osteoporosis
  • icon
    Unexplained infertility or recurrent miscarriage
  • icon
    First degree relatives of people with coeliac disease*
  • icon
    Persistently raised liver enzymes with unknown cause
  • icon
    Dental enamel defects
  • icon
    Down’s, Turner or Williams Syndrome
  • icon
    Immunoglobulin A (IgA) deficiency

*A first degree relative (parent, sibling, child) of someone with coeliac disease has a 10% chance of also having the disease. If one identical twin has coeliac disease there is an approximate 70% chance that the other twin will also have coeliac disease (but they may not necessarily be diagnosed at the same time). Immediate relatives of someone with coeliac disease should always be screened.
