Gut Health Nutritionist London: Supporting your gut health through personalised nutrition and lifestyle
As a London based gut health nutritionist, we help you navigate and resolve complex digestive health issues.
​
Did you know your gut is often called the “second brain”? It continuously communicates with the rest of your body, influencing everything from your digestion to your energy levels, mood and immune function. A balanced gut is the foundation of good health, playing a crucial role in nutrient absorption, metabolism, mental well-being, immune regulation, and maintaining a balanced internal ecosystem.
​
In our clinic, we see clients struggling with a wide range of symptoms including persistent abdominal pain, bloating, acid reflux, irregular bowel movements, indigestion, constipation, flatulence, diarrhoea and food sensitivities. Beyond these, issues such as chronic fatigue, headaches, skin conditions, food cravings, recurring thrush, histamine intolerance, grass allergy, can all be linked back to underlying gut imbalances.​​ DIY solutions like relying on Google, asking ChatGPT for gut health advice, or following fad diets can often backfire. Not every method like "the low FODMAP diet", suits everyone, not all probiotics are effective, and gluten or dairy aren't always the main culprits.
As a registered nutritional therapist and gut specialist, I don't believe in one-size-fits-all solutions. Our extensive experience allows us to create gut-balancing plans that look beyond symptom management, addressing root causes of your gut symptoms that may fall outside the remit of standard GP care or gut dieticians. Our programmes are evidence-based, tailored to your unique circumstance and designed to preserve the joy of eating. Where appropriate, we recommend targeted supplements and provide clarity in selecting the most relevant functional tests from world-leading laboratories (not available through the NHS). You can feel confident knowing you are in safe, expert hands.

Ready to take the first step toward lasting relief? Book your free discovery call to discuss your concerns. We will not only listen to your concerns and suggest the best programme to restore your gut health, but will take the time to celebrate the little wins along the way - like slipping into clothes that once felt too tight, or enjoying a meal without the worry of acid reflux or diarrhoea.

Success Stories
Specialising in IBS, bloating & other gut conditions
Our personalised programmes offer targeted and holistic support for common gut conditions that disrupt digestion and nutrient absorption helping clients feel pain-free, lighter, more energised, and truly revitalised.
​
IBS (Irritable Bowel Syndrome)
Irritable Bowel Syndrome, commonly known as IBS, is a functional gastrointestinal disorder that affects how the gut moves and processes food. It can cause a range of disruptive symptoms, including bloating, abdominal pain, cramping, diarrhoea, constipation, or a combination of both. IBS is often linked to heightened gut sensitivity, stress, and dietary triggers, making it a highly individualised condition. Beyond digestive discomfort, IBS can also impact energy levels, mood, and overall quality of life. Our personalised programmes focus on identifying your unique triggers, restoring gut balance, and calming the nervous system. Many clients notice not only more predictable digestion but also improved energy, reduced discomfort, and greater confidence in enjoying food without constant worry.
​
Dysbiosis
An imbalance in the gut microbiome - the community of bacteria, fungi, and other microorganisms residing in the gastrointestinal tract - referred to medically as dysbiosis, can lead to a variety of symptoms, including bloating, indigestion, food cravings, diarrhoea, constipation, and abdominal discomfort. Dysbiosis may also contribute to nutrient deficiencies, weight fluctuations, inflammation, skin conditions, thrush, and dental issues like cavities.
​​​
SIBO (Small intestinal bacterial overgrowth)
SIBO occurs when there is an excessive growth of bacteria in the small intestine, leading to symptoms such as bloating, abdominal pain, irregular bowel movements (including diarrhea or constipation), and fatigue. This overgrowth can interfere with nutrient absorption, potentially causing deficiencies in vitamins like B12, iron, and fat-soluble vitamins A, D, E, and K.
​
Leaky gut syndrome & food sensitivities
When the gut lining becomes overly permeable, larger-than-normal particles, such as undigested food molecules and toxins, can pass into the bloodstream, triggering systemic inflammation, weakening immunity, and increasing sensitivity to foods, such as dairy or gluten, or environmental factors, such as pollen, dust, or wheatgrass. This disruption impairs digestive health leading to symptoms like bloating, abdominal discomfort, and inconsistent bowel movements.
Holistic gut health support that goes beyond digestion: Nurturing your gut-brain connection and more, in our whole-body consultations
The gut is at the heart of your overall health, influencing not just digestion but also mental clarity, hormone balance, immune resilience, long-term resilience and health. Our personalised programmes take a strategic, whole-body approach, addressing these interconnected systems with evidence-based solutions that help you feel energised, focused, and empowered - covering digestion and its impact on your overall health.
​
The gut-brain axis
The gut–brain axis is a powerful, two-way communication system between the digestive tract and the nervous system. Up to 90% of serotonin, the neurotransmitter often called the “feel-good hormone,” is produced in the gut. Imbalances in gut bacteria can disrupt this pathway, contributing to low mood, anxiety, or brain fog. By focusing on microbial diversity and reducing gut inflammation, we help clients experience sharper mental clarity, greater emotional resilience, and a calmer state of mind.
​​​
Gut health and hormonal balance
Gut health also underpins hormone regulation. A balanced microbiome supports the metabolism of oestrogen, cortisol, and other key hormones that govern energy, sleep, and stress response. When the gut is out of balance, it can disrupt these processes — leading to fatigue, irregular cycles, or difficulty managing stress. By restoring gut function, we help rebalance hormones naturally, supporting both physical vitality and emotional well-being.
​
Gut-immune connection
With 70% of the immune system residing in the gut, this is the body’s first line of defence. A compromised gut barrier can fuel chronic inflammation, sensitivities, and recurrent illness. Through targeted nutrition, lifestyle strategies, and advanced functional testing, my programmes strengthen the gut–immune connection, helping clients build a robust foundation for long-term health.
