She adds that a healthy microbiome supports many vital body functions, including digestion, immunity, and metabolism. It may also influence your baby's immune system and early gut colonisation.
However, she said that the microbiome is only one part of the picture in determining your baby's long-term health.
How Can Your Gut Microbiome Affect Your Baby?
Research suggests that the maternal gut microbiome may have a role in your baby's early immune development. However, scientists are still studying exactly how this happens.According to Dr Lipi Sharma, the maternal microbiome may influence:
- Your baby's developing immune system
- Early immune responses
- Early gut colonisation
How may a mother’s gut microbiome impact a developing baby’s health?
The microbiome of your gut produces certain substances that may influence your immune and metabolic functions.Research suggests that changes may influence the maternal environment during pregnancy.
However, it does not suggest that your gut microbiome may prevent or cause a specific health issue in your baby.
Your baby's health is also influenced by:
- Genetics
- Nutrition
- Pregnancy health
- Birth-related factors
- Environment
- Early feeding and lifestyle
