Do I have coeliac disease?

There are no specific symptoms of coeliac disease, and many people with coeliac disease have no obvious symptoms at all. Symptoms you may experience include:

If you are worried about any of these symptoms, make an appointment to see your GP.

If you have a first-degree relative (mother, father, brother, sister, or child) with coeliac disease, then you have a 10% chance of having it as well.

Coeliac disease tests and diagnosis

Important!

Don't start a gluten-free diet until you have been diagnosed with coeliac disease, as you need to be eating gluten to get accurate test results. If you have been on a gluten-free diet you will need to return to a normal diet for four to six weeks before testing. During this time, you will need to eat at least four slices of wheat-based bread (or equivalent) daily.

Your GP will ask you if you have any coeliac-related symptoms, and will discuss your family history and overall health and lifestyle.

If it's possible that you might have coeliac disease, you'll need to have a screening blood test. If this test shows you might have coeliac disease, you will need to have a procedure called a gastroscopy. This is done at Christchurch Hospital Gastroenterology Department. The gastroscopy is free but you may have to wait up to three months to have one.

If you prefer, or if you don't want to wait, you can pay to have a gastroscopy done privately.

This page from Coeliac New Zealand explains more about tests for coeliac disease.
