Did you know that hidden in the walls of our digestive system, we have a second brain called the gut-brain-axis and it is transforming our understanding of the links between good gut health and mood?
The gut-brain-axis (GBA) consists of a two-way communication between our brain and our enteric nervous system, (neurons in our gut that control the function of our gastrointestinal tract).
This system of nerves in our gastrointestinal system has over 100 million neurons!!! This system has so many nerves our gut has earned the nickname “the gut brain” or “the second brain”.
Stress, anxiety and depression can have a direct impact on our “gut brain” and how well our gut works, and vice versa.
Our “gut brain” is influenced by our sympathetic (“fight or flight”) and parasympathetic (“rest and digest”) modes and sends signals along the vagus nerve (an information highway) to our brain, relaying important messages about what’s going on.
This can influence how well our gut functions and helps explain why during times of worry, anxiety and stress (fight or flight) we may experience:
This two-way communication between our brain and our gut brain influences how we feel and think on a daily basis. A prime example of this in action is the feeling of butterflies in our stomach when we feel nervous or anxious before an important meeting or exam.
Probiotics and good gut bacteria support anxiety, mood and mental health
The balance of our gut bacteria matter when it comes to mental health. Recent advances in gut health research has highlighted the importance of certain gut bacteria in this bi-directional communication.
The health of our gut and the variety of our gut microbes influence how we think and how we feel.
Addressing leaky gut or any other gut imbalances is an essential step when it comes to supporting mental wellbeing, such as:
How does the gut brain and our actual brain communicate?
Our gut bacteria chat with our brain and vice versa and use different modes of communication, including:
The health of our gut has an effect on our brain and how we feel from day to day. Inflammation, a lack of microbial diversity and even specific species of gut bacteria have been linked with poor mental health including anxiety, low mood and depression. Research shows that altering bacteria in the gut through specific dietary changes may help to treat stress-related mood disorders and anxiety.

I’d love to know if you are incorporating any of my tips on how to reduce the risk of bloating? But, if you feel you have already tried absolutely EVERYTHING, and you have been given the all-clear by your GP but you are STILL struggling with excessive bloating, belching or gas, it might be time to consider Small Intestinal Bacterial Overgrowth, or “SIBO”.
What is SIBO?
SIBO is when normal bacteria get moved from the large intestine into the small intestine where they can cause digestion problems, including excessive bloating and/or belching. SIBO is thought to be behind about 60% of IBS cases.
How can I get tested for SIBO in the UK?
Why test for SIBO?
Firstly, it’s helpful to get tested for SIBO so we know what we’re dealing with and so that once we have followed a nutritional programme we can retest to see how your levels are changing.
What is the SIBO test?
A SIBO test is a breath test where you collect multiple samples of breath over a three hour period. It measures levels of hydrogen and methane gases which will be produced if bacteria are present in the small intestine.
How can I get tested for SIBO?
To test for SIBO in the UK, you can try requesting a SIBO breath test from a GI consultant (requires referral by a GP) or, you can order one from me, a BANT registered Nutritional Therapist.
I've saved a story to my Instagram stories here to show you how the SIBO breath test works. It is very simple to complete at home. You can find a list of all the clinical test options I provide, including prices here. Full instructions on how to prepare for your SIBO test and complete the test are provided.
If you suspect SIBO, book a free call and we can chat further and make sure SIBO testing is the right test for you. You may also enjoy reading 'What Causes SIBO' and what to do if you test positive for SIBO here.
Nutritional Therapy helps identify the underlying causes of IBS symptoms and personalises a gut-healing plan that addresses:
You can also find out more about IBS here. I think you'll find it refreshing!
Nutritional Therapy works alongside medical treatment and should not be misconstrued as a replacement for medicine. I always work with your GP to ensure you get the best support and results. I can also write to your GP if necessary and/or advise you of tests available on the NHS so you can discuss further with your GP (if you are in the UK).
Please be aware that IBS must be diagnosed by a medical doctor so that serious disease can be ruled out. And if you experience any of the following please consult your doctor urgently:
