Wellness Begins in More Places Than We Realise
When we think about hormones, we often focus on the ovaries, thyroid or adrenal glands. Yet one of the most influential contributors to hormonal wellbeing may be somewhere we rarely consider: the gut.
Our digestive system is home to trillions of microorganisms—including bacteria, fungi and other microbes—that together form what scientists call the gut microbiome. Far from being passive passengers, these microorganisms help digest food, support the immune system, produce important nutrients and communicate with many other systems throughout the body.
Emerging research suggests that the health of the gut microbiome may also influence how our bodies regulate certain hormones, particularly oestrogen. While this area of research is still developing, it highlights an important message: caring for your gut may support much more than digestion.
Meet Your Gut Microbiome
Every person has a unique community of microorganisms living within their digestive tract. Together, these organisms help maintain a healthy digestive environment and perform countless functions essential to wellbeing.
- A balanced gut microbiome contributes to:
- Digesting certain foods and dietary fibre.
- Producing vitamins such as vitamin K and some B vitamins.
- Supporting the immune system.
- Helping maintain the intestinal barrier.
- Communicating with the nervous system through the gut-brain axis.
The diversity of this microbial community matters. A varied, balanced microbiome is generally associated with better overall health than one with reduced diversity.
The Estrobolome: A Fascinating Area of Research
One of the most exciting discoveries in recent years is the estrobolome—a collection of gut bacteria involved in metabolising oestrogen.
After oestrogen has been processed by the liver, some of it enters the digestive tract before leaving the body. Certain gut bacteria help determine whether some of this hormone is broken down further or reabsorbed into circulation.
Researchers are investigating how changes in the gut microbiome may influence this process. Although the science is still evolving, there is growing interest in how gut health may contribute to hormonal balance throughout different stages of a woman's life.
Importantly, scientists have not yet established that improving the microbiome directly treats hormonal conditions. Instead, current evidence suggests that maintaining a healthy gut may support the body's natural regulatory systems.
Hormones and the Gut During Midlife
Perimenopause and menopause bring natural changes in hormone levels, particularly declining oestrogen.
At the same time, researchers have observed that the composition of the gut microbiome may also change with age. While scientists are still exploring exactly how these changes interact, there appears to be a complex two-way relationship between hormones and gut health.
Some women notice digestive changes during this stage of life, including:
- Increased bloating.
- Altered bowel habits.
- Greater food sensitivities.
- Changes in appetite.
- Fluctuations in energy levels.
These symptoms are influenced by many factors and cannot be attributed solely to the microbiome. Nevertheless, supporting digestive health remains an important part of overall wellbeing.
The Gut-Brain Connection
Have you ever noticed "butterflies" before an important event or a loss of appetite during stressful times?
These experiences reflect the close communication between the gut and the brain.
This two-way communication network, known as the gut-brain axis, involves the nervous system, hormones, immune signals and the gut microbiome.
Research suggests that the gut and brain constantly exchange information, influencing digestion, stress responses and aspects of emotional wellbeing. While scientists continue to investigate these interactions, it's becoming increasingly clear that mental and digestive health are closely connected.
Looking after your gut is therefore also part of looking after your overall wellbeing.
Everyday Habits That Support Gut Health
The good news is that many habits that benefit your gut also support your general health.
Consider incorporating:
Eat More Fibre
Whole grains, legumes, vegetables, fruit, nuts and seeds provide nourishment for beneficial gut bacteria.
Aim to increase fibre gradually and drink enough water to support comfortable digestion.
Include Fermented Foods
Foods such as plain yoghurt with live cultures, kefir, kimchi, sauerkraut and miso may contribute beneficial microorganisms to the diet.
Not everyone enjoys these foods, and they are only one part of a balanced eating pattern.
Choose a Variety of Plant Foods
Research consistently suggests that dietary diversity supports microbial diversity.
Rather than eating the same foods every day, try introducing a wider range of colourful fruits, vegetables, herbs, legumes and whole grains throughout the week.
Stay Physically Active
Regular physical activity benefits digestion, metabolism, cardiovascular health and may also positively influence the gut microbiome.
Even moderate movement such as walking can contribute to overall wellbeing.
Prioritise Quality Sleep
Poor sleep can affect many aspects of health, including digestion and hormone regulation.
Creating a calming evening routine and maintaining a consistent sleep schedule support both your body and mind.
Manage Stress with Compassion
Chronic stress influences digestion through the gut-brain axis.
Gentle practices such as mindful breathing, yoga, journalling or spending time outdoors can help support emotional resilience while benefiting overall wellbeing.
What About Probiotics?
Probiotics have received significant attention in recent years, and research into their potential benefits continues to grow.
However, probiotics are not a universal solution.
Different strains perform different functions, and evidence varies depending on the health condition being studied.
For many healthy adults, building a fibre-rich, varied eating pattern remains one of the most effective ways to support the gut microbiome.
If you're considering probiotic supplements for a specific health concern, it's worth discussing them with your healthcare professional, particularly if you have underlying medical conditions or are immunocompromised.
Wellness Is About Connections
One of the most exciting developments in modern health research is the growing appreciation that the body's systems rarely work in isolation.
Hormones influence digestion.
Digestion influences immunity.
The gut communicates with the brain.
Lifestyle affects every one of these relationships.
Rather than searching for a single solution, long-term wellbeing is often built through consistent daily habits that support the body as a whole.
Looking After Your Future Self
Supporting your gut isn't about following the latest wellness trend.
It's about creating everyday habits that nourish your entire body.
A colourful plate.
Regular movement.
Restful sleep.
Managing stress.
Meaningful social connection.
These simple choices work together over time to create a stronger foundation for lifelong health.
While research into the gut-hormone connection continues to evolve, one message is already clear: caring for your digestive health is an investment in your overall wellbeing, today and for the years ahead.
