What is Lifestyle Medicine and how do I get it from my GP?

For many centuries medical treatment has been sought mostly for “acute” problems – acute means an illness with trauma, pain, fever, or infection which requires an immediate diagnosis and treatment. Once correctly treated, usually with medication or surgery, most acute illnesses will resolve, with return to normal functioning in a short period of time.

Now, for the first time in history, the prevalence of “chronic disease” has overtaken acute disease as the main reason why modern patients see a doctor. Chronic diseases are mostly caused by lifestyle and environmental factors, and over the last 30-40 years have risen in prevalence to account for approximately 70% of all primary health care visits in developed countries1

Over the past four decades, with the rapid advancements in agriculture, manufacturing and processing, and now digital technology, mankind has seen significant changes in food types, dietary patterns, daily activity levels and general lifestyle behaviours. Unfortunately, these rapid changes in diet and activity levels have contributed to an emergence of chronic diseases of pandemic proportions2,3. The list is long and includes conditions such as Type 2 Diabetes, overweight/ obesity, high blood pressure, pre-diabetes, high cholesterol, heart disease, chronic fatigue, emphysema, hip and knee joint pain, back pain, chronic stress and many forms of depression and anxiety.

The challenge is that they do not make a person feel ill until they have progressed to a point where organs or systems are under stress and already not functioning properly. Diagnosis is therefore delayed unless appropriate screening is in place. Unfortunately, they also cannot usually be cured with medication alone because the cause of the illness remains, so they exist indefinitely which is why they are termed “chronic” meaning “to persist for a long time or constantly recurring”. The scary statistic is that these conditions now make up the top 5 causes of death in Australia for those in the over-45 age categories2 (see image 1).

Today’s General Practitioners (GPs) are experts in managing both acute and the measurable parameters of chronic disease, such as blood pressure control or sugar control. Managing the CAUSE of chronic disease is different, and lies in addressing “lifestyle choices” and assisting with modification of health behaviour.

In a standard GP practice setting, unfortunately, this remains problematic4: patients usually want a quick fix (even better if in pill-form!) and GP’s are well intended but time and resource poor and often unable to address the complexities of the underlying behavioural or environmental causes. This high turnover, medication-focused approach severely limits the establishment of the deeper Doctor-Patient relationship that is required for meaningful change.

Lifestyle Medicine (LM) is the newest field of sub-specialisation in modern medicine. The specialty first came to light in 1999 with the publication of the first Lifestyle Medicine textbook, and the field of practice has only gained worldwide momentum among GPs and Allied Health Professionals (such as nurses, psychologists, dietitians and exercise physiologists) in the last few years1. Lifestyle related health problems are PREVENTABLE and in many cases, REVERSIBLE, so as the name suggests, Lifestyle Medicine addresses both the cause, and the “cause-of-the-cause” and can often reverse early to medium onset chronic disease by assisting patients through evidence-based lifestyle and behaviour modification.

Lifestyle Medicine is an evidence-based approach that bridges the gap between the old and new, between medical knowledge and common sense and is the shining light at the end of a very dark chronic disease tunnel. It is defined as “the application of environmental, behavioural, medical and motivational principles to the management (including self care and self-management) of lifestyle-related health problems in a clinical and/or public health setting.1

To me, however, the most beautiful aspect of this clinical specialty is that “it is inexpensive and even cost-saving; free of all but good side effects; safe and appropriate for children and octogenarians alike. It is, quite simply, the best medicine we’ve got.”5

As a Lifestyle Medicine physician I have learned, over time, that for anyone to maintain the motivation6 to make sustainable change, their “WHYs” and their “HOWs” have to be clearly defined. To this point, with regard to LM, I hope that I have clearly explained:

  • WHY you may want to understand the concept of Lifestyle Medicine.
  • WHY, although being evidenced-based conventional medicine, it differs in its approach to chronic disease.
  • WHY it addresses the underlying cause and the “cause-of the-cause”2,3 of chronic disease.

If you are a patient who would like to lose weight, change your lifestyle habits, prevent your chronic disease risk factors, or manage or potentially reverse your chronic disease, then it is also important that you establish your “WHYs”. This means setting your vision and your goals. By knowing WHY you have set these goals you can clearly define your pathway to that goal.

Only once you’ve set your goal and know your pathway, then can you determine HOW best to follow that path.

In the next section I’d like to guide you on:

  • HOW to get Lifestyle Medicine from your Doctor or Allied Health Professional

  • HOW you could apply the principles of Lifestyle Medicine yourself to assist you in achieving your weight loss, risk factor reduction, disease reversal or overall wellness goals.

  • HOW you might like to frame your own health within the “Bio-Psychological-Social” framework of complete wellbeing.

How do you get Lifestyle Medicine from your GP or Allied Health Professional?

In reality you do not actually “get” Lifestyle Medicine as you would get medication or surgical intervention. In Lifestyle Medicine, your GP or AHP acts as a facilitator or “coach” and provides you with the education and the tools (the “Why’s” and the “How’s”) to travel the pathway to achieving your goal. You become the “driver”.

In summary, you and your GP may like to apply the fundamentals of health by focusing on a holistic approach, namely the “Bio-Psycho-Social” model of care. The World Health Organisation defines “Health” as:
WHO definition of health

As I explained in my introduction, Lifestyle Medicine is an emerging field and it may not be easy to find a GP or AHP that can apply all the principles of evidence-based information and couple that with support and behavioural change techniques. Rest assured, easier access is around the corner as the pandemic of chronic disease cries out for a different approach to medical care. And that approach is Lifestyle Medicine7.
