Research, including ours, has shown that pregnancy brings incredible changes to your body, including the gut! The gut microbiome shifts significantly to support both mother and baby. The microbial diversity (number of different types of microbes) tends to decrease; however, your gut becomes better at absorbing energy and nutrients, an important change that helps fuel your baby’s development.
Why is a healthy microbiome important during pregnancy?
- Immune Function: A balanced microbiome regulates immune responses, preventing both infections and excessive inflammation.
- Blood Sugar Balance: Certain microbial imbalances can cause insulin resistance, especially in the later trimesters. A healthy microbiome may reduce the risk of gestational diabetes and help stabilise blood sugar levels.
- Digestive Support: Hormonal shifts slow down digestion, allowing more time for the gut to break down food. This causes a boost in energy-harvesting bacteria that help nourish you and your baby.
- Baby’s Long-term Health: the mother’s microbiome shapes the baby’s microbiome, immunity and metabolism. Research shows that a healthy diet and microbiome during pregnancy lowers the risk of obesity, allergies and behavioural disorders.
Safe ways to support your microbiome during pregnancy:
- Plant-based foods, leafy greens,
- Staying hydrated
- Keeping active
- Getting sufficient sleep
- Reducing stress with mindfulness or yoga.
The Bottom Line
Caring for your gut during pregnancy supports smoother digestion, balanced blood sugar, and a stronger immune system while also giving your baby the healthiest start possible. Simple daily habits can make a big difference for you both.
