Healthcare labels
Functional, integrative, holistic and alternative medicine:what is the difference?
The words overlap, but they do not mean the same profession, training or evidence base. Compare the practitioner, their registration, the proposed treatment and how it fits with care you already need.
These labels do not tell you the same thing.
Functional, integrative, holistic and alternative medicine are approach labels, not interchangeable professional qualifications. The safest way to compare them is to separate the label from the person using it. Ask who the practitioner is, what profession they belong to, what they are qualified to do, and how the proposed care fits with established medical treatment.
The NHS uses “complementary” for treatments used alongside conventional healthcare and “alternative” for treatments used instead of it. Specialist Pharmacy Service uses the same distinction when discussing complementary products with prescribed medicines. [1] [2]
What do the four terms usually mean?
There is no single UK statutory definition that turns each of these labels into one regulated profession. Their meaning can vary between clinics and practitioners. That is why the underlying professional role matters more than the marketing term.
| Label | Useful plain-English meaning | What the label does not prove |
|---|---|---|
| Functional medicine | An approach that often looks across history, lifestyle, medicines, previous results and possible contributing factors before deciding what further assessment is useful. | It does not by itself prove that the practitioner is a registered doctor, that a test is validated, or that a treatment is effective. |
| Integrative medicine | A broad term for combining conventional medical care with selected complementary approaches when appropriate. | It does not mean every complementary treatment has good evidence, or that conventional care becomes optional. |
| Holistic care | A way of considering the person as a whole, including physical symptoms, mental wellbeing, lifestyle, social context and treatment burden. | It is not a protected medical specialty title and does not tell you the practitioner’s legal scope. |
| Alternative medicine | A treatment or system used instead of conventional medical care. | Using a therapy as an alternative can create risk if it replaces treatment that is needed for diagnosis, monitoring or disease control. [2] |
Start with the practitioner, not the label.
If someone describes themselves as a doctor, check the GMC register. It shows whether the person is registered and whether GP or specialist registration is recorded. [3]
Other professions have their own regulators or registers. For example, “dietitian” and “dietician” are protected titles regulated by the HCPC. Complementary disciplines may use voluntary accredited registers such as the CNHC, which currently includes fields such as naturopathy and nutritional therapy. [4] [5]
A register does not prove that every treatment a practitioner offers works. It helps you understand the person’s professional identity, standards and scope. Evidence for an intervention still needs to be judged separately.
“Holistic” does not mean “non-medical”.
A registered doctor can take a holistic approach. So can a dietitian, physiotherapist or another regulated clinician within their own scope. Looking at sleep, stress, nutrition, activity, family circumstances and medicine burden can be part of ordinary good clinical care.
The important distinction is not whether a practitioner says they are holistic. It is whether they can safely assess the problem, recognise when another professional is needed, and stay within their competence. Persistent symptoms may need a doctor, dietitian, mental-health professional, physiotherapist, specialist or more than one professional.
A registered doctor may describe their work as functional, integrative and holistic at the same time. Those words can describe an approach, while the GMC registration describes the professional role.
Check what the person is legally and professionally qualified to do.
Judge each test or treatment on its own evidence, benefits, limits and risks.
Complementary and alternative are not the same safety decision.
Using a complementary approach alongside necessary medical care is different from replacing that care. The NHS advises people to tell healthcare professionals about complementary products and therapies, because there can be safety issues, including medicine interactions. [1]
Specialist Pharmacy Service advises that complementary products should not replace conventional medicines where those medicines are needed. It also recommends checking the ingredients and considering interactions or duplicated doses. [2]
Homeopathy is a separate example. NHS medicines guidance states there is no good-quality evidence that homeopathy is effective for any health condition. That evidence position should not be blurred with the evidence for nutrition, exercise, sleep interventions or licensed medicines simply because they all appear under a broad “holistic” umbrella. [6]
How should you compare two clinics using different labels?
Ignore the label for a moment and compare what would actually happen. Ask who takes responsibility for medical assessment, how medicines are reviewed, which tests may be discussed, how evidence is explained, when referral is recommended and what costs sit outside the consultation.
Then compare whether the practitioner’s registration matches the task. A medical diagnosis, prescribing decision or assessment of red-flag symptoms needs an appropriately qualified clinician. Nutrition-focused support may involve a different professional. A complementary therapy should not be presented as a substitute for urgent, specialist or evidence-based treatment when that treatment is needed.
A label is not an evidence grade
“Functional”, “integrative”, “holistic” and “alternative” do not tell you whether a specific treatment works. Ask for the evidence for the actual intervention being proposed, not evidence for a neighbouring intervention or for the label itself.
A simple way to choose your next step
Start with the problem you want help with. Write it down in one sentence. Then ask what kind of professional is best placed to deal with that problem.
If you need a medical diagnosis, a review of symptoms, a prescription or a check for serious illness, start with a doctor or the relevant medical service. If the main need is food and diet support, ask what nutrition qualification the person holds and whether a dietitian is needed. If you want a complementary therapy, ask how it will sit beside the care you already receive.
Next, ask what will happen at the first visit. Will the practitioner take a full history? Will they review current medicines and past test results? Will they tell you what they can and cannot do? Will they refer you on when a problem sits outside their scope?
Finally, ask about cost before you agree to tests, products or a long care plan. A clear answer should separate the consultation fee from optional tests, supplements or other treatment. You should also know who will review results and what happens if the first plan does not help.
These checks are simple, but they cut through vague labels. They help you compare real care rather than marketing language.
What should a good first visit tell you?
You should leave with a clear plan. You should know what the main health questions are, what has already been checked, and what may need more work. You should know which part of the plan is medical care and which part is an added choice.
You should be free to ask why a test or treatment is being offered. A clear answer should tell you what the test may show, what it may miss, and how the result could change the plan. If the answer is vague, ask again before you pay.
You should also know who is in charge of each part of your care. One person may lead the main review, while another may help with food, movement or mental health. That can work well when the roles are clear. It can be less safe when no one knows who is meant to act on a result or a new symptom.
Keep a list of your medicines and share it with each person involved in your care. Do not stop a prescribed drug just because a new approach has been suggested. If you are not sure how two parts of a plan fit together, ask the doctor or prescriber who knows your medical history.
Most of all, you should feel able to say no. A sound care plan can be changed when a test, product or treatment does not fit your needs, values or budget.
One last check before you choose
Read the page again and look for plain facts. Can you see the person’s name and role? Can you check their register? Are the fees clear? Is there a clear plan for tests and follow-up? Does the site say when another doctor or service may be needed? If those points are hard to find, ask before you book.
Where does Dr Stavy’s approach sit?
Dr Stavy is presented on this site as a GMC-registered doctor whose functional-medicine work is intended to remain integrated with conventional and specialist care. The broader functional medicine explainer describes the model and its limits, while the functional medicine consultation page explains the doctor-led assessment route.
This page does not imply that every intervention described as functional, integrative or holistic is offered by Dr Stavy. It also does not treat those labels as guarantees of effectiveness. The purpose is to help you understand the language before you compare individual clinicians and treatments.
What patients say about the consultation experience.
Patient reviews can help you understand how a consultation feels. They do not prove that a particular diagnosis will be found or that a treatment will work.
Individual reviews reflect personal experiences and do not predict diagnosis, treatment response or outcome.

Common questions
Is functional medicine the same as integrative medicine?
Not exactly. The terms overlap, but neither is a single protected UK professional title. Functional medicine often describes a structured way of exploring history, lifestyle and possible contributors. Integrative medicine usually describes combining conventional care with selected complementary approaches. The practitioner’s registration and the evidence for each treatment matter more than the label.
Is holistic medicine a medical specialty?
No. “Holistic” is a broad description of looking at the person as a whole. It does not by itself show whether someone is a doctor or another regulated professional. If a practitioner uses a medical title, check the relevant professional register and what their registration allows them to do.
What is the difference between complementary and alternative medicine?
Complementary approaches are used alongside conventional healthcare. Alternative approaches are used instead of it. That difference matters when conventional diagnosis, monitoring or treatment is necessary. The NHS advises discussing complementary products and therapies with healthcare professionals, especially if you take prescribed medicines.
Does being on a professional register prove a treatment works?
No. Registration helps verify the professional’s identity, standards and scope. Evidence for a treatment is a separate question. A registered clinician can offer an intervention with strong, weak or uncertain evidence, so ask what evidence supports the specific test or treatment being proposed.
Can a doctor use complementary approaches?
Yes, provided the doctor works within competence, explains evidence and uncertainty, considers medicine interactions and does not allow complementary care to replace necessary medical treatment. The exact approach varies by clinician, so ask what is being proposed and why.
How do I compare practitioners using different labels?
Check professional registration first. Then compare scope, evidence, testing rationale, medicine responsibility, referral arrangements, costs and what happens if the proposed approach does not help. Those practical questions are usually more informative than whether a website uses the words functional, integrative or holistic.
