Chronic Fatigue

A Functional Medicine Approach to Chronic Fatigue

Chronic fatigue Syndrome is characterized by persistent fatigue and other specific symptoms with potentially many contributing factors. The fatigue is not specifically due to exertion and is not caused by other medical conditions.  Unfortunately, often patients are left going around the conventional health system without getting better.  

The causes of chronic fatigue are incredibly diverse, from sleep issues, toxin exposures, hormonal imbalance, key nutrient deficiencies, gut issues, hidden infections, auto immune disease, psychological, genetic, food intolerance which can severely your day to day life. 

Sufferers of Chronic Fatigue Syndrome can see their symptoms appear gradually after a period of sustained physical or emotional stress, or it can appear very suddenly which seems like a bout of the flu that just won’t go away. 


Chronic Fatigue Causes

Our Functional Medicine practitioners seek to address the main underlying causes of these debilitating symptoms so we can treat them more effectively and get you back to an improved quality of life, as we understand how this condition can heavily impact patients’ family, work and social activities.

Considerations for our practitioners can include

→ Heavy Metal Toxcity
→ Neurotransmitter                depletion
→ Hormone imbalance
→ Inflammation

→ Emotional distress
→ Gut infections
→ Environmental toxicity
→ Food sensitivities/allergies

We will also look to take a detailed history and see what other factors that be contributing to your symptoms, so we can piece together any information that can help determine the imbalance.

Common Symptoms

Chronic Fatigue Treatment

At the London Centre for Functional Medicine, our treatment protocols vary with each patient based on the core imbalances that are interfering with the body’s ability to function correctly. A typical approach to treating chronic fatigue syndrome (CFS) can include identifying and addressing underlying factors in your lifestyle that can be contributing to the condition e.g. stress, poor sleep hygiene, sedentary lifestyle.

One of the first places we start to investigate is the gut, even if there are no gut symptoms, a person may be harboring a chronic yeast, bacteria, virus or parasite infection that can be detected using PCR testing. Dysbiosis (more bad bacteria than good bacteria) can also be a contributory factor. Typically, depending on what we find, we will look to remove any pathogens, replace the nutrients and enzymes, repair the gut lining and repopulate the microbiome. Undiagnosed oral and chronic viral infections can also be a major factor that we look to investigate with reactivated viral infections a major consideration. Hormone health impact everything that happens in your body. To overcome fatigue and achieve true health, you need your hormones appropriately balanced. We will look to test your hormone levels and if we discover any abnormalities we can readdress the balance through various protocols which have nutrition and lifestyle at their core.​

If you have fatigue, some forms of exercise have shown to be helpful but exercise can also make things worse. The way to fix your fatigue therefore often involves a range of targeted physical, biochemical, nutritional, and psychological treatments.

Chronic Fatigue Approach

Optimal Nutrition and Absorption

Imbalances in our digestive system can contribute to absorption issues. If we are not absorbing correctly, it means we are not getting the fuel we need for cells to function and generate energy from food.

Supplement Support

Depending on test results, your practitioner can recommend some targeted supplements to help support the powerhouses of our cells called the mitochondria.


We work on the motto of testing rather than guessing which can be quicker and cheaper in the long run. Our practitioners can recommend specific testing related to chronic fatigue, such as urinary hormone testing (Dutch test), a comprehensive microbiome and stool analysis along with any other testing that can help with our investigations.

Targeted Treatments

Our functional practitioners can recommend additional treatment or lifestyle interventions that can be extremely beneficial in overcoming chronic fatigue such as IV treatment or ozone therapy

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.
