Leaky Gut Syndrome

A Functional Medicine Approach to Leaky Gut Syndrome

Leaky Gut is also commonly known as gut hyperpermeability, involves a malfunction of the filtering system of the small intestine. The small intestine is comprised of the duodenum, jejunum and ileum, and spans from the stomach to the large intestine, or bowel.

A healthy small intestine allows absorption of nutrients while also preventing the absorption of undigested food particles, bacteria, fungi and toxins. When a person’s gut lining becomes damaged gut lining, small tears, like you would see in a cheese cloth allows increasing amounts of toxic substances into the body. setting up an immune system response, which can result in inflammation in different parts of the body. Consequently, foreign particles to the body can get into tissues triggering a host of symptoms that can appear in many body systems that may seem to be distinct from the digestive tract.

Leaky Gut Causes

A leaky gut process can involve pathogenic microorganisms within the digestive tract that ferment on undigested food which produces toxic by-products, and when they die, fragments of their cell walls (known as LPS or lipopolysaccharide) are released and absorbed into the bloodstream. Endotoxins/lipopolysaccharide can cause inflammation causing an immune response and are the cause of much of the damage that arises from a Leaky Gut.

Rob has helped me through a gut health conditon that no other GP was able or willing to figure out. There was no guess work involved. He got to the root of my issues through knowledge, testing and investigation. I would highly recommend the London Centre for Functional Medicine

I can’t say enough good things about my experience at the London Centre for Functional Medicine. After 3 years of misdiagnosis and living with IBS I finally felt I was able to heal. I’m truly grateful to Rob for his expertise in SIBO. I have to keep things in check but I feel so much better. I would highly recommend them.

I'm currently going through treatment with Rob and just wanted to acknowledge the individualised and personalised care that has been provided. From when I started Rob has looked at my health issues without judgement and was able to help me in many areas that weren't optimal. Notably, Rob has helped me overcome gut issues and other niggling issues that I didn't were related but seemingly are. Rob is also great at explaining the body systems and related things which has been great. I can highly recommend the London Centre for Functional Medicine

"What I appreciate about Rob at the London Centre for Functional Medicine is that he seeks to educate rather than just give supplements and instructions. He makes you understand both the action needed to take as well the underlying physiological processes driving the underlying issues. Highly recommended."

If you're dealing with health challenges that conventional medicine hasn't resolved, I strongly suggest you visit the London Centre for Functional Medicine. They make a real effort to comprehend symptoms and worked with me to develop a plan for exploring treatment possibilities. Thanks to my practitioner, I now have answers to health questions that had eluded me for years, and I couldn't be more grateful. My practitioner (rob) uses a data-driven approach to identify the underlying cause. I've already recommended him to friends, and they have had success with his care as well.

Rather than going to a GP when you are sick I entered the Functional Medicine journey before things got out of hand. It’s a route everyone should consider as it does prevent illness and can reverse it! I learned a lot about how my body works and how to become healthier. London CFM walked me through the things I needed to know by educating me about how the digestive system works and healing my SIBO. Thank you!

I was originally referred to Mr Staunton by a nutritional therapist who felt that his particular expertise was required for my specific needs. After meeting him and explaining the situation, he conducted some lab tests which had to be shipped to Germany.. In the 3 months that I’ve been treated by Mr Staunton, I’ve seen a significant improvement in my symptoms and I’m feeling optimistic about my continued good health. I highly recommend the Clinic and working with Mr Staunton has been a very professional and pleasant experience. He’s extremely knowledgeable about both nutrition and how the body works.
