Meet Esra Gulsen
Esra Gulsen is a functional and integrative medicine practitioner at NAR LONDON, known for her thoughtful, analytical, and compassionate approach to care. She works closely with clients who feel unheard, stuck, or overwhelmed by persistent symptoms, helping them identify root causes and build realistic, sustainable healing plans.
Esra believes symptoms are meaningful signals – not problems to suppress. By listening carefully to the body and combining modern science with integrative health principles, she empowers clients to take informed control of their health journey.
What Is Integrative & Functional Medicine?
Integrative and functional medicine is designed for people who want answers—not guesswork. Rather than focusing on isolated symptoms, this approach looks at how the body’s systems work together and what may be driving imbalance.
Your care considers:
- Medical and family history
- Nutrition, digestion, and metabolism
- Hormone balance and stress response
- Sleep, energy, and emotional wellbeing
- Lifestyle, environment, and daily habits
This whole-person perspective allows for truly personalised healthcare, tailored to your unique biology and life circumstances.
The Functional Medicine Approach
Functional medicine is a cornerstone of Esra’s work. It focuses on how and why illness develops – at the cellular and systems level – so the body’s natural healing capacity can be supported.
Instead of masking symptoms, functional medicine aims to:
- Identify root causes
- Correct underlying imbalances
- Optimise physiological function
- Support long-term resilience and prevention
Each plan is personalised and evolves as your health improves.
A Thoughtful, Multi-Disciplinary Framework
Depending on your individual needs, your personalised plan may draw from multiple integrative disciplines, including:
- Functional Medicine – Root-cause, systems-based care
- Naturopathic Principles – Supporting the body through “right living”
- Orthomolecular Medicine – Optimising essential nutrients
- Bioregulatory Medicine – Enhancing innate healing mechanisms
- Traditional Chinese Medicine & Herbalism – Restoring balance and flow
- Ayurvedic Medicine – Ancient insights for harmony and vitality
- Mind–Body Approaches – Addressing the nervous system and stress response
Not every modality is used for every person – your plan is designed specifically for you.
Who This Approach Is For?
Working with a functional medicine practitioner in London may be right for you if:
- You have persistent or recurring symptoms without clear answers
- You feel rushed or unheard in conventional appointments
- You want a proactive, preventative approach to health
- You’re ready for personalised, lifestyle-based care
Common areas of support include hormone imbalances, digestive issues, chronic fatigue, stress and burnout, metabolic concerns, and inflammatory conditions.
How does the Integrative Health Programme Works?
Comprehensive Initial Assessment
Your journey begins with an in-depth consultation exploring your health history, current symptoms, lifestyle, and goals.

You’ll receive a tailored 12–16 week protocol that may include:
- Targeted nutrition strategies
- Supplement guidance (when appropriate)
- Gut, hormone, or metabolic support

Ongoing Review & Support
Healing is a process. Follow-ups allow for refinement, education, and progress tracking as your body responds.

- Food intolerance panels
- Thyroid and adrenal hormone testing

Testing is optional and always used strategically to enhance – not complicate – your care.
