Understanding the condition

Coeliac disease is an autoimmune condition, not a food allergy or a simple intolerance. When you eat gluten, a protein in wheat, rye and barley, your immune system damages the lining of the small bowel.1 Symptoms range from bloating and diarrhoea to tiredness, or none at all, and many people with the condition have never been diagnosed.1 Testing needs to happen while you are still eating gluten, because cutting it out first can make results unreliable. If you have already stopped, talk to your doctor before testing.2

Treatment is strict, lifelong gluten free eating, which lets the bowel heal.1 An Accredited Practising Dietitian teaches you how to read labels, avoid cross-contact at home and keep your diet balanced, including iron, B vitamins, calcium and vitamin D, and sees you for regular follow-up.3,4 Oats cannot be labelled gluten free under Australian and New Zealand food law, and while most people with coeliac disease tolerate pure oats, it is best to discuss them with your medical team first.5 Simple kitchen habits, such as clean utensils and no double dipping, make cross-contact manageable.6

What to look out for, and how we help

Symptoms are a guide, not a diagnosis. Your GP confirms the diagnosis; our team helps you manage it day to day.

What you might notice

  • Bloating, abdominal pain, wind, nausea or diarrhoea after eating foods containing gluten
  • Constipation, tiredness or low energy
  • Iron deficiency anaemia or low levels of other nutrients found on blood tests
  • Unexplained weight loss, low bone density or a family history of coeliac disease
  • Some people have no symptoms at all, so coeliac disease is often found through testing
  • Red flag: see your doctor promptly for unexplained weight loss, iron deficiency anaemia or symptoms that continue despite a gluten free diet, and do not cut out gluten before you have been tested. Call 000 in an emergency.

How our team helps

  • Assessment of what you eat, your symptoms and your medical history, including your test results
  • A personalised gluten free eating plan that keeps your diet balanced and covers iron, calcium, B vitamins and vitamin D
  • Label reading and shopping skills, including hidden sources of gluten and how to approach oats
  • Cooking demonstrations and practical kitchen tips to avoid cross-contact at home
  • Advice if you have already cut out gluten, so you can talk to your doctor about testing before going further
  • Review appointments, with coordination with your GP, pharmacist and diabetes educator

Common questions

Do I need to keep eating gluten before a coeliac test?
+

Yes. Blood tests and a biopsy are most reliable while you are eating gluten, and cutting it out first can give misleading results. If you have already stopped, talk to your doctor about whether you need to eat gluten again before testing.

Is coeliac disease the same as a gluten allergy?
+

No. Coeliac disease is an autoimmune condition where gluten damages the lining of the small bowel. It needs a proper diagnosis from your doctor or specialist, and gluten free eating should only start once that is confirmed.

Can I eat oats with coeliac disease?
+

Under Australian and New Zealand food law, oats cannot be labelled gluten free. Most people with coeliac disease tolerate pure oats, but it is best to discuss them with your medical team first. We can help you plan around that advice.

How long do I need to eat gluten free?
+

Strict gluten free eating is lifelong, because it is how the bowel heals. We make it practical with an eating plan and review appointments, which usually become less frequent once you are well and your nutrient levels are steady.

Do I need a referral to see a dietitian for coeliac disease?
+

No referral is needed for private appointments. A Medicare rebate needs a GP Chronic Condition Management Plan and a GP referral, and applies to up to five eligible allied health services a calendar year. Private health extras, NDIS or DVA funding may also apply, so ask us when you book.

Not sure where to start?

Tell us what is going on and we will point you to the right discipline, or to more than one. Most people start with a single appointment and leave with a plan the rest of the team can see.
