The Healthy Gut Diet Study is a randomised controlled trial that is designed to test whether women can be supported to change their gut microbiome through diet and if this, can prevent gestational diabetes mellitus (GDM). Women with a prior history of GDM are the target group, as they are far more likely to develop it in subsequent pregnancies.
Why the Healthy Gut Diet?
Research in recent years has shown that women with GDM have a different gut microbiome to pregnant women without this common disorder. In fact, the microbiome of women with GDM is more similar to (non-pregnant) adults with type 2 diabetes.
Is there a link between the gut microbiome and glycaemic control? Almost certainly! It is known that probiotic supplementation produces a mixed bag of results (and may even be harmful), and the study is interested in the effect of a Healthy Gut Diet on the gut microbiome and the development of GDM.
Who is eligible?
Why should you care?
GDM is the most common disorder a woman can experience during pregnancy – more than 1 in 7 pregnant women will be diagnosed with GDM. There are short- and long-term risks of GDM to mother and child. About 50% of women with GDM will go on to develop type 2 diabetes within 10 years. Preventing or improving the management of GDM can have intergenerational impacts.
How can you help?
If you are a GP, antenatal health care provider or friend/family of a pregnant woman in Queensland, please share this post or talk to your patients/friends about this study. GPs are ideally placed to encourage women to join the study as you see women early in their pregnancy.
