Functional Medicine for Cancer Patients

Your cancer journey deserves compassionate, evidence-informed support. Functional medicine for cancer patients works alongside standard oncology care, using research-backed complementary therapies to help manage symptoms, reduce treatment side effects and improve quality of life. This is not about replacing chemotherapy, surgery or radiotherapy—it’s about addressing root causes of ill health, supporting your body’s natural resilience and helping you feel your best.

Is Functional Medicine for Cancer Patients Right for You?

Undergoing active treatment such as chemotherapy, radiotherapy, immunotherapy or hormone therapy and looking for help managing fatigue, nausea, sleep problems or anxiety.
In remission or post-treatment, wanting to rebuild strength, restore your microbiome, regulate hormones and reduce recurrence risk.
Living with chronic or advanced cancer, seeking to improve energy, digestion, mood or overall quality of life while coordinating with your oncology team.
At high genetic or family risk, interested in targeted prevention, metabolic optimisation and longevity strategies.

Every plan is tailored to your diagnosis, treatment stage, lifestyle and goals.

An Integrative, Supportive Approach

Integrative medicine uses therapies developed outside of Western medicine—such as meditation, yoga, acupuncture and nutritional strategies—in coordination with standard treatments to relieve symptoms and side effects. Unlike alternative medicine, which replaces standard care, integrative therapies are used alongside conventional treatments and should be evidence-based.

Functional medicine is a personalised form of integrative care that identifies and addresses root causes of illness. In cancer care this means:

Supporting gut health and the microbiome with diet, fibres and probiotics to enhance digestion and detoxification.
Balancing hormones to mitigate treatment-related changes and improve energy.
Enhancing immune function and inflammatory balance to strengthen resilience during and after treatment.
Promoting detoxification pathways and mitochondrial function to reduce fatigue and support recovery.
Addressing mental and emotional health through stress-management techniques, sleep optimisation and mindfulness.

Importantly, functional medicine practitioners do not claim to cure cancer; they work collaboratively with oncology teams to enhance overall health and quality of life.

How Functional Medicine Supports Cancer Patients

Modern integrative oncology recognises that combining conventional treatments with evidence-based complementary therapies can reduce symptom burden and improve outcomes. Our functional medicine service may include:

Personalised Nutrition

Cancer and its treatments often disrupt appetite, digestion and metabolic balance. We design nutrition plans that consider your treatment stage, weight changes and dietary preferences. By focusing on anti-inflammatory foods, balanced macronutrients and microbiome-supportive fibres, we help you maintain strength and stabilise blood sugar. Supplements are recommended only when they’re safe and unlikely to interact with medications.

Gut and Microbiome Support

Chemotherapy and antibiotics can alter gut flora and cause nausea, diarrhoea or constipation. We use targeted prebiotics, probiotics and herbal therapies, alongside dietary changes, to restore microbial balance and reduce GI side effects. Improving gut health also enhances immune function and nutrient absorption.

Energy, Fatigue and Recovery

Fatigue is a common side effect of cancer treatment. We assess factors such as mitochondrial function, anaemia, thyroid and adrenal health, and develop plans to support energy production through nutrient optimisation, gentle movement and restorative sleep routines.

Immune and Inflammatory Balance

A well‑regulated immune system helps your body tolerate treatment and recover more quickly. We address inflammation through diet, stress reduction, detoxification support and, when appropriate, targeted nutraceuticals. Our goal is to modulate the immune response without overstimulation.

Metabolic and Hormonal Health

Cancer therapies can impact weight, blood sugar and hormones. We track metabolic markers and provide guidance on insulin regulation, muscle preservation and hormonal balance, supporting both men and women through treatment and into survivorship.

Mental and Emotional Resilience

Integrative therapies like meditation, breathing exercises, hypnosis and yoga can help reduce anxiety and pain. We offer mind‑body techniques and coaching to foster emotional resilience, improve sleep and empower you throughout your cancer journey.

Your Care Pathway With Dr Stavy

Pre‑consultation – You complete a detailed questionnaire and share your medical history, cancer diagnosis, treatments and medications.
Initial consultation (60–90 minutes) – We explore your symptoms, lifestyle, diet, stress levels, sleep patterns and goals. Together we clarify what you’d like to achieve: symptom relief, improved energy, reduced recurrence risk or long‑term health optimisation.
Advanced testing (if appropriate) – Where necessary, we may recommend tests to evaluate nutrient status, gut health, metabolic, hormonal and inflammatory markers. All tests are considered in the context of your oncology care.
Personalised care plan – You receive a tailored plan covering nutrition, gut support, stress management, sleep, movement and safe supplementation. Recommendations are evidence‑based and designed to complement your oncology treatment.
Ongoing review and survivorship support – We regularly review your progress, adapting the plan to your treatment cycles and recovery phases. Once treatment ends, we transition to long‑term survivorship and longevity care.

Safety and Collaboration

We always review oncology reports, medication regimens and treatment protocols before making recommendations. Integrative therapies should never interfere with cancer treatments.

Our team communicates with your oncologist or GP (with your consent) to ensure safe, coordinated care.

The Society for Integrative Oncology emphasises that guidelines are tools, not rules; clinicians must balance evidence, safety and patient preferences when recommending complementary therapies.

I came to Dr Stavy tired, not sleeping properly, having body ache, worried about my health in the future and within 4 months, my life started to transform. I changed my diet and took the supplements she had recommended and miraculously these problems started to melt away. Our bodies have the ability to heal, they often just need the raw ingredients to start functioning properly and Dr Stavy really understands that. I still have a few issues to deal with, but with Dr Stavy’s guidance, I have no doubt that these will be remedied soon too. Put your faith in her, she won’t let you down.

Dr Stavy was a God sent angel that saved me from GP appointments, tons of harmful medicines and long waiting list nhs referral. I was at the end of the rops, hopeless, physically and mentally broken… thanks to Dr Stavy and their team, I haven’t been back to GP, I am not taking any of those nasty steroid tablets and immune therapy injections… I cannot recommend her enough and both my husband and a friend are so happy that they see Dr Stavy after i recommended. Functional medicine and holistic therapies take a bit of time, patience and dedication to treat the causes of the issue but Dr Stavy makes the journey easy, she is so knowledgeable, kind, friendly and caring. If you’re like me in 6 month ago and reading reviews to decide which Functional medicine Dr to choose, don’t hesitate to see her, she is the best.

I have been treated by Dr Stavy for a few months now. She has a kind and gentle approach, which is invaluable when talking about something as sensitive as health. She listens to what I say and takes my concerns seriously, which is wonderful and refreshing.

There is still some way to go, but through changes to diet, my IBS, which I had for about 15 years has gone, my sinus issues have greatly improved and I am no longer dizzy. I’ve also lost quite a bit of weight, which is a great and has improved my confidence.

Having a previous bad experience with homeopathy doctors, I was sceptical. Dr Stavy though is an excellent practician, hit the point from our first meeting, but most important she is an uderstanding person, with great instinct and very supporting towards me! Qualities I value the most! Thank you Dr Stavy for everything, I am lucky to have found you!

It was 20 years ago, that I met Stavroula! Kidney stones and extracorporeal lithotripsy did not work. The large stone did not break and I was getting ready for surgery. Stavroula took it upon herself to help me! About a year later, with patience and persistence and a lot of colic, the stone came off and came down! That’s how we started and “tied”!!!
Since then, whatever problem I had, pathological, orthopedic but also psychological, I went to Stavroula!!
Always with a sweet talk, with patience but also with scolding whenever needed!
Thank you my dear!!!
Be strong!!!

17:28 17 Apr 24

Dr stavvy is the best! I Couldn’t recommend her enough! In 2021 I was at a point where I was going to need a life altering operation then I come accross dr Stavy and within 3/4 months I was back to my normal self and pregnant! All with natural and homeopathy treatments. I still have a routine check up with Dr Stavy to this day to make sure everything’s as it should be. I owe this lovely lady my life and she has changed my whole outlook on modern medicine. If I were ever to be sick again Dr Stavy would be the first person I would call before any doctor!!!

I have been in touch with Dr Stavy for 5 or 6 years now and find the Functional medicine approach very helpful. I’ve had ME for a long time and conventional medicine is only able to treat/suppress the symptoms whereas the tests I’ve done for Dr Stavy have helped pinpoint some of the causes of my symptoms. She is easy and sympathetic to talk to and always very encouraging. She feels like a friend and it is good to know that she is there to support me when needed. I have also found her homeopathic treatment helpful.

Dimitris P.

Can you work with me if I’m being treated in the NHS or abroad?
Yes. We work with patients receiving care in the NHS or overseas, coordinating our recommendations with your local oncology team.

What tests do you recommend?
Testing is personalised. We may suggest blood tests, stool analyses or metabolic panels if they can meaningfully guide your care.
