Who Can Practice Lifestyle Medicine in Viet Nam? Professional Roles, Scope of Practice and Legal Boundaries

Who Can Practice Lifestyle Medicine in Viet Nam? Professional Roles, Scope of Practice and Legal Boundaries

Last reviewed: September 2026

As Lifestyle Medicine becomes better known in Viet Nam, an important practical question is beginning to emerge: who can actually practice Lifestyle Medicine?

The question sounds simple, but the answer requires some care. Lifestyle Medicine is interdisciplinary. Physicians, nurses, clinical nutrition professionals, clinical psychologists and other healthcare professionals may all contribute to lifestyle-based care. Professionals working in exercise, coaching, public health and community settings may also support healthier behaviors. But these roles are not legally interchangeable, and an international Lifestyle Medicine qualification does not replace the licensing and scope-of-practice requirements that apply in Viet Nam.

It is therefore helpful to separate two questions that are often mixed together. Who can contribute to Lifestyle Medicine through education, prevention, behavior-change support and related activities? And who can provide medical examination and treatment using lifestyle interventions? Depending on what is actually being done, the answers may be different.

Lifestyle Medicine is not a separate licensed professional title in Viet Nam

Under Vietnamese law, Lifestyle Medicine is not currently a separate professional title requiring a practising license.

Article 26 of the Law on Medical Examination and Treatment identifies the professional titles that require practising licenses. These include physicians, assistant physicians, nurses, midwives, medical technicians, clinical nutrition professionals, pre-hospital emergency care professionals, clinical psychologists and specified traditional medicine practitioners. “Lifestyle Medicine physician” and “Lifestyle Medicine practitioner” are not separate titles on that list.

In practical terms, Lifestyle Medicine does not replace the profession underneath it. A physician may incorporate evidence-based nutrition, physical activity, sleep, stress management, avoidance of harmful substances, social connection and behavior-change approaches into patient care, but must do so within the physician's authorized scope of practice. The same principle applies to nurses, clinical nutrition professionals, clinical psychologists and other regulated healthcare professionals.

This is also broadly consistent with the international development of the field. The Lifestyle Medicine Core Competencies were designed to define knowledge and skills relevant across different medical and healthcare disciplines, rather than to suggest that every profession performs the same clinical functions. The 2025 update specifically notes that some competencies may fall outside the scope of practice of non-provider healthcare professionals.

International certification should be understood in the same way. A recognized Lifestyle Medicine qualification can provide evidence of additional education, knowledge or professional competence. It does not, by itself, create a Vietnamese practising license, convert one professional title into another or automatically expand the scope recorded or authorized under Vietnamese law.

The legal boundary is not simply whether someone prescribes medication

One of the most important points in understanding this area is that Vietnamese law defines medical examination and treatment more broadly than prescribing medicines, ordering tests or performing procedures.

Under the Law on Medical Examination and Treatment, medical examination involves the use of professional knowledge, methods and techniques to assess a person's health status, health risks and healthcare needs. Treatment includes the use of professional knowledge, methods and techniques to address disease, prevent its occurrence or progression, or meet healthcare needs on the basis of the medical examination.

This matters for Lifestyle Medicine because an activity does not automatically fall outside medical practice simply because it involves food, exercise, sleep or behavior rather than medication.

Providing general information about healthy eating, for example, is different from assessing an individual with diabetes, chronic kidney disease and hypertension and developing a therapeutic nutrition intervention as part of disease management. Encouraging the public to become more physically active is different from clinically evaluating a patient with cardiovascular disease and developing an individualized exercise prescription based on that person's medical risks. Discussing good sleep habits is different from assessing symptoms suggestive of obstructive sleep apnea and making clinical decisions about investigation, treatment or referral.

The name given to an activity is therefore not enough to determine its legal character. What is actually being done, for whom, for what purpose and with what level of clinical decision-making matters more.

Vietnamese law also prohibits medical examination or treatment when the applicable professional requirements are not met, as well as practice outside the authorized professional scope. The same principle applies to healthcare facilities operating without the required license or outside their approved scope.

Physicians have an important role in clinical Lifestyle Medicine

When Lifestyle Medicine is used to manage established disease, physicians will often have an important clinical role. Many patients who may benefit from intensive lifestyle interventions already live with obesity, hypertension, type 2 diabetes, cardiovascular disease or multiple chronic conditions. Their care may involve diagnosis, assessment of clinical risk, interpretation of investigations, medication management, monitoring and decisions about referral.

Within an authorized scope of practice, physicians can incorporate lifestyle assessment and evidence-based lifestyle interventions into conventional clinical care. This becomes particularly important when substantial changes in diet, physical activity, weight or other behaviors affect blood glucose, blood pressure or other clinical parameters and existing treatment may need to be reassessed.

Lifestyle intervention and conventional medical treatment should therefore not be presented as competing systems. In many patients they need to work together, with treatment adjusted according to clinical response and patient needs.

Additional Lifestyle Medicine training does not, however, give a physician unlimited clinical authority. The physician's professional title, licensed scope of practice, qualifications, training and the applicable regulations remain relevant. Lifestyle Medicine education adds competence. It does not remove the boundaries of the underlying medical license.

Clinical nutrition is a regulated professional area

Nutrition is one of the most visible components of Lifestyle Medicine, but there is an important distinction between general nutrition education and clinical nutrition as part of healthcare.

Vietnamese law recognizes clinical nutrition (dinh dưỡng lâm sàng) as a professional title requiring a practising license. Circular 32/2023/TT-BYT sets out its scope of practice in Appendix XV. Clinical nutrition professionals can therefore play an important role in multidisciplinary Lifestyle Medicine care within their authorized professional scope.

This may include nutritional assessment, appropriate nutrition interventions and patient support where these activities fall within the legally authorized scope of the professional concerned. The distinction becomes especially important when nutritional care is being used in the management of a person with an established disease or complex clinical condition.

Terminology can easily create confusion. Terms such as “nutrition coach,” “nutrition consultant,” “nutritionist,” “dietitian” and the statutory Vietnamese professional title “clinical nutrition” should not automatically be treated as legally equivalent. A title used in marketing or translated from another country does not, by itself, establish what someone is legally authorized to do in Viet Nam. Qualifications, professional licensing where required, authorized scope and the actual service being delivered all need to be considered.

Nurses can be major contributors to Lifestyle Medicine care

Long-term lifestyle change rarely happens during a single consultation. It often requires education, monitoring, follow-up, reinforcement, care coordination and support for self-management. Nurses are well positioned to contribute to many of these activities.

Vietnamese law recognizes nursing as a professional title requiring a practising license, and Circular 32/2023/TT-BYT defines the professional technical scope for nursing. Circular 25/2026/TT-BYT subsequently amended parts of the nursing technical appendix, with those amendments taking effect from July 1, 2026.

Within their authorized scope, nurses can contribute to patient education, monitoring, care coordination, support for agreed care plans and other components of long-term lifestyle-based care. Their role can be particularly valuable in chronic disease management, where repeated contact and continuity are often as important as the initial clinical plan.

Team-based Lifestyle Medicine should therefore not be designed around the physician alone. At the same time, working as part of a multidisciplinary team does not authorize one profession to assume clinical functions that belong outside its own scope of practice.

Clinical psychologists can address important behavioral and psychological dimensions of health

Knowing what is healthy is not the same as being able to change behavior. Stress, depression, anxiety, habits, emotional regulation, social circumstances, motivation and readiness to change can all influence whether a person can translate health information into daily life.

Clinical psychology is one of the professional titles requiring a practising license under the current Law on Medical Examination and Treatment. Circular 32/2023/TT-BYT provides a defined scope for clinical psychology, including continuous and comprehensive care relating to cognition, behavior, emotions and psychosocial health, as well as specified psychological assessment and intervention activities in healthcare facilities.

This is highly relevant to Lifestyle Medicine, where behavior change is a core area of professional competence. Motivational interviewing, collaborative goal setting, therapeutic alliance, self-efficacy and relapse prevention can all contribute to sustainable change. These methods are not necessarily exclusive to clinical psychologists, and appropriately trained professionals may use relevant behavior-change skills within their own roles. Psychological assessment, diagnosis and treatment, however, must remain within the professional and legal boundaries applicable to those activities.

Other professionals also have a place in the Lifestyle Medicine ecosystem

Lifestyle Medicine is inherently multidisciplinary, but multidisciplinary care does not mean that every member of the team has the same legal authority.

Physicians and medical technicians working in rehabilitation can contribute within their respective authorized scopes. Pharmacists can support safe medication use, adherence and medication-related education under the legal framework governing pharmacy practice. Preventive medicine physicians and public health professionals can contribute to prevention, risk reduction, population health, research and community interventions according to their qualifications and roles. Exercise professionals can help people become more physically active, while appropriately trained coaches can support goal setting, accountability and the development of sustainable routines.

The health coach is a useful example of why these distinctions matter. “Health coach” is not one of the professional titles requiring a practising license under Article 26 of the Law on Medical Examination and Treatment. That does not mean health coaching has no legitimate role. A coach may help a person clarify goals, build routines, identify barriers, maintain motivation and follow an agreed plan.

But the absence of a separate licensed title does not create permission to perform activities that legally amount to medical examination or treatment. A health coach, fitness professional or wellness educator should not present coaching credentials as independent authority to diagnose disease, make medical treatment decisions, prescribe or discontinue medication, or provide clinical care outside a professional scope for which that person is legally authorized.

This distinction protects patients while allowing non-clinical professionals to make useful contributions where their roles are clearly defined.

Prevention and health education have a broader place outside clinical care

Not every Lifestyle Medicine-related activity is medical examination or treatment.

This distinction has become even more relevant since the Law on Disease Prevention No. 114/2025/QH15 took effect on July 1, 2026. The law covers the prevention and control of communicable diseases, noncommunicable diseases and mental disorders, as well as nutrition in disease prevention. It expressly includes information, education and communication concerning behavior and lifestyle change for disease prevention.

The law also requires prevention information and communication to be accurate, scientific, clear, understandable, practical and appropriate to the population and context. This provides a clearer national legal and policy context for evidence-based prevention and health education, including activities delivered through communities, educational institutions, workplaces and other settings, subject to the other laws and regulations that apply to those activities.

There is therefore an important space for public education about nutrition, physical activity, sleep, tobacco and other harmful exposures, stress, social connection and other health-related behaviors without automatically turning every educational activity into medical treatment.

The boundary becomes more important when an activity moves from general education and prevention to the individualized clinical assessment or treatment of a particular person's health condition. At that point, the Law on Medical Examination and Treatment, the professional scope of those involved and the licensing status of the facility become increasingly important.

The setting matters, not just the professional

A person's professional license is only one part of the legal framework. The setting through which clinical care is provided also matters.

The Law on Medical Examination and Treatment defines a medical examination and treatment facility as a facility licensed by a competent Vietnamese authority to provide medical examination and treatment services. The law also prohibits a facility from providing such services without an operating license or outside its permitted professional scope.

This means that having a licensed physician on a team does not automatically turn a wellness center, training company, gym, education provider or coaching organization into a licensed medical examination and treatment facility.

Similarly, business registration is not the same as a license to operate a medical examination and treatment facility. An organization may legitimately provide education, training, prevention, communication or behavior-support services within the legal framework applicable to those activities. But if what it actually provides constitutes medical examination or treatment, calling the service “wellness,” “coaching,” “health optimization” or “Lifestyle Medicine” does not remove the healthcare requirements that apply.

This is another reason to focus on the substance of the activity rather than its branding.

What does international Lifestyle Medicine certification mean in Viet Nam?

International Lifestyle Medicine education and certification can make an important contribution to professional development. Such programs can strengthen knowledge of lifestyle interventions, behavior change, evidence-based practice and chronic disease management.

But professional competence and legal authorization are different questions.

An international Lifestyle Medicine certification should therefore be described as an additional professional credential or evidence of relevant education where appropriate. It should not be represented as a Vietnamese practising license or as automatically expanding the holder's existing legal scope of practice.

This distinction is particularly important when international terminology is used. A person may legitimately hold a professional designation in another country or through an international certification body, but the right to provide regulated healthcare in Viet Nam continues to depend on Vietnamese law.

What about foreign healthcare professionals?

A foreign physician or other healthcare professional does not automatically gain unrestricted authority to practice clinically in Viet Nam simply because they hold a foreign professional license or an international Lifestyle Medicine qualification.

The Law on Medical Examination and Treatment provides specific rules for foreign professionals. It also provides defined pathways under which a foreign professional holding an overseas practising license may participate in episodic humanitarian medical care, cooperation in medical training involving medical examination and treatment, or the transfer of professional medical techniques, subject to the conditions and procedures prescribed by law.

This distinction matters for international Lifestyle Medicine collaboration. Giving a lecture, participating in professional education and directly examining or treating patients are not the same activity. When a foreign expert becomes involved in patient assessment or treatment, the applicable medical practice requirements need to be considered. Immigration, labor, education and other regulatory requirements may also apply depending on the particular arrangement.

For organizations working with international experts, the safest approach is to define the person's role clearly before the activity takes place.

A practical way to think about scope of practice

When there is uncertainty about whether a Lifestyle Medicine activity crosses into regulated clinical practice, the most useful approach is to look at what is happening in practice.

Is the person providing general health information, or assessing the health status and medical risks of an individual? Are they helping someone implement a plan that has already been established appropriately, or independently diagnosing and treating disease? Are they interpreting laboratory results or other clinical information in order to make treatment decisions? Are they recommending that medication be started, stopped or changed? Does the activity fall within that person's authorized professional scope? If medical examination or treatment is being provided, is it being delivered through an appropriately licensed healthcare facility?

No single question will resolve every situation, but together they provide a useful way to distinguish general education and supportive care from regulated clinical practice.

What should Lifestyle Medicine practice look like in Viet Nam?

A practical model for Viet Nam is to integrate evidence-based Lifestyle Medicine into mainstream healthcare rather than build a parallel clinical system outside existing professional and regulatory structures.

Physicians can strengthen their ability to assess lifestyle-related risks and use lifestyle interventions as part of clinical care. Nurses can contribute to education, monitoring and long-term patient support. Clinical nutrition professionals can provide specialized nutritional care within their authorized scope. Clinical psychologists can contribute behavioral and psychological expertise. Rehabilitation, pharmacy, public health and other professionals can contribute according to their respective qualifications and professional boundaries. Health coaches, exercise professionals and community-based workers can help people translate appropriate health goals into daily behavior without taking over functions that require clinical authorization.

This model also reflects the reality of chronic disease. Sustainable change rarely results from one professional, one consultation or one prescription. Lifestyle Medicine works best when care is evidence-based, coordinated and person-centered, and when each professional understands both what they can contribute and where their professional boundaries lie.

So, who can practice Lifestyle Medicine in Viet Nam?

The most accurate answer is that, as of September 2026, Viet Nam does not have a separate professional title requiring a practising license called “Lifestyle Medicine physician” or “Lifestyle Medicine practitioner.”

Licensed healthcare professionals can incorporate relevant Lifestyle Medicine principles and interventions into their work within their professional qualifications, authorized scopes of practice and applicable clinical settings. Other professionals can make valuable contributions through prevention, education, behavior-change support, coaching, exercise and community-based activities, provided that they do not cross into medical examination or treatment for which they are not legally authorized.

An international Lifestyle Medicine qualification can strengthen professional competence, but it does not replace Vietnamese licensing requirements. A non-clinical setting does not become a medical facility simply because a healthcare professional works there. And a service does not fall outside healthcare regulation simply because it is described as lifestyle, wellness or coaching.

These boundaries should not be seen as obstacles to the development of Lifestyle Medicine. They provide a framework within which the field can develop responsibly, protect patients and remain firmly connected to evidence-based healthcare.

As Lifestyle Medicine grows in Viet Nam, the most useful question may therefore be less about who can claim the title of a Lifestyle Medicine practitioner and more about this:

How can each profession contribute its appropriate expertise to evidence-based Lifestyle Medicine while protecting patients, respecting professional boundaries and building better models of care?

That is a more sustainable foundation for the development of Lifestyle Medicine in Viet Nam.
