Coeliac Disease and Fertility
When we think about coeliac disease we tend to think about gut problems. Bloating, diarrhoea, stomach pain and lots of discomfort. The traditional view of coeliac disease was that it happened to children (who grew out of it) and was all about weight loss and really sick tummies. But we now know that coeliac disease can affect much more than just the gut. Migraines, fatigue, nerve damage and mouth ulcers are all now recognized as possible signs that someone should be tested for coeliac disease. In recent years, fertility has also been recognized as something that is affected by coeliac disease. We know that women with undiagnosed coeliac disease are more likely to experience problems with fertility compared to women without coeliac disease. These problems can include more difficulty becoming pregnant as well as a greater chance of having a miscarriage. Babies born to women with coeliac disease may also be a lower birth weight or have other problems. Sadly, having undiagnosed coeliac disease increases the risk of having a stillborn baby.
The good news is that once women with coeliac disease are diagnosed and following a strict gluten-free diet, then their fertility goes back to normal and they do not have any greater problems than anybody without coeliac disease.
How can coeliac disease affect fertility?
There are several ways that untreated coeliac disease can affect how easy it is for someone to become pregnant or to have a healthy baby:
What can we do to help fertility in women with coeliac disease?
The most important thing to do is to make sure that you are following a strict gluten free diet. Many people with coeliac disease have never seen a dietitian for advice. If you have never seen a dietitian or if it has been a few years since you were last seen, do ask your GP to refer you to your local HSE dietitian or you can find a list of private CORU registered Dietitians at www.sedi.ie. The Coeliac Society now has a specialist dietitian clinic where you can see a CORU Registered dietitian. Make sure you do see a CORU registered dietitian as they are the only nutrition experts in Ireland who are qualified to treat coeliac disease and it is important that you get the right advice at this stage.
Along with following a strict gluten-free diet you may need some additional supplements. Although all women who are thinking about having a baby should take 400mcg of folic acid everyday, women with coeliac disease may need more. You may need up to 5000mcg of folic acid per day. This is only available on prescription so do talk to your GP and Dietitian about whether or not you need the higher dose.
People with coeliac disease can have difficulty absorbing all of the calcium that they need so it is important to make sure you are eating enough foods that are rich in calcium during your pregnancy. Milk, cheese and yoghurt are all good sources. Calcium-fortified plant milks and tofu are useful sources of calcium. You will also find calcium in tinned salmon and sardines. Although there is calcium in green vegetables, it is very difficult to eat enough of these to get all of the calcium that you need (you would need around 5 bags of rocket a day…). Do talk to your dietitian about calcium in your diet.
I am not coeliac but I am struggling with fertility – what can I do?
Problems with fertility can have lots of causes so it may not be coeliac disease. However, if you have been struggling with fertility it is worth talking to your GP about having a coeliac test. 1 in in 100 people in Ireland are coeliac but many are never diagnosed. Do not just cut out gluten “to see”. It is really important to be tested for coeliac disease before you cut out gluten. Although the traditional symptoms of coeliac disease are bloating, diarrhoea and weight loss, many people do not have these symptoms. Depression, migraine, osteoporosis, mouth ulcers, and problems with fertility can all be symptoms of coeliac disease. You may also have no symptoms. Remember that coeliac disease does run in families so you have a 1 in 10 chance of being coeliac if a close relative has already been diagnosed.
How do we test for coeliac disease?
Your GP can carry out a simple blood test. If this test is positive your GP will refer you to a gastroenterologist (special gut doctor) for a biopsy. You need to have the biopsy to be diagnosed with coeliac disease: the blood test alone is not enough. It is very, very important that you continue to eat gluten until you have your biopsy. If you cut out some or all gluten before you have your test, then it will come back as negative even if you do have coeliac disease.
