Longevity: From disease control to prevention

Longevity refers to living a long life, which has become a major focus in modern health science. As people live longer, researchers are looking at the factors that influence both how long we live (lifespan) and how healthy we remain as we age (healthspan).

In the past, medical science focused on treating diseases after they appeared. Today, the focus is shifting towards preventative medicine, helping people stay healthy before serious health issues develop.

This change is crucial as our population ages.

Data tells us that while lifespan has increased by about 30 years over the last century, the ratio of healthy years of life (healthspan) has not increased accordingly. In fact, the rates of chronic diseases have increased [1].

There’s an increase in the number of years we spend being unhealthy and unwell. Unable to make the most of our remaining time.

For example, the average lifespan in Switzerland today is 83.4 years, while the average healthspan is 72.5 years [2] (World Health Organization, 2024). We could spend over 11 years towards the end of our lives with an illness that limits our quality of life.

Traditional disease control approaches

As understanding of illness progressed [3], so did treatments. Early medical figures like Hippocrates and Galen focused on treating illness, though their knowledge was limited to the technology of their era. 

Germ theory, developed by Louis Pasteur in the 1860s, marked a turning point. By linking germs to illness, medicine began focusing on disease prevention through better sanitation. From the 19th century onward, this proactive approach led to a drop in deaths from infectious diseases. 

However, to understand the modern challenge, let’s look at some data. 

The four most common conditions—cancers, cardiovascular disease, chronic respiratory conditions, and metabolic disorders—account for 80% of chronic disease-related deaths [4]. Chronic diseases combined account for approximately 71% of all deaths.

These diseases are not related to germs or infections. They arise from within and have different causes, influenced by factors like genetics, lifestyle, and environment [5].

Historically, medical care has been reactive, focusing on treating diseases after they manifest. Even in the modern era, many treatments address symptoms rather than preventing disease in the first place. 

For example, heart disease is treated with medications like statins or surgeries for blocked arteries, while diabetes is managed with insulin or medications to control blood sugar. Cancer treatments such as chemotherapy and surgery are also reactive, often starting after the disease has progressed. 

While these treatments are essential, they don’t address the root causes before disease develops.

The shift to prevention

Today, there’s a growing emphasis on preventative medicine, which focuses on early detection and lifestyle interventions. Doctors are now identifying risk factors for conditions such as high blood pressure or elevated blood sugar and acting before they happen. Being proactive about health can significantly reduce the risk of developing serious diseases.

This shift is part of what leading longevity voice, Dr. Peter Attia, has referred to as ‘Medicine 3.0.’

Medicine 1.0 encompassed early medical practices. An emphasis on disease management and traditional treatments. Medicine 2.0 brought advancements through the 20th century and was highly successful in reducing deaths related to contagious or communicable diseases. It’s seen no real change in the rates of death due to chronic health conditions though. 

It’s clear that a new approach is needed.

In Switzerland, just 4% of total healthcare spending goes toward prevention, while roughly 80% is allocated to treating non-communicable chronic diseases. Over half of these conditions could be prevented or delayed through a healthy lifestyle and preventative actions.[6]

Medicine 3.0 focuses on using modern technology and preventative medicine to help people live longer, healthier lives.

Preventative medicine is very individualized. It is a precision science that targets specific markers and informs personalized treatment plans.  

There are also more general lifestyle changes known to have a positive influence on longevity. It is important to note, that even for these lifestyle interventions, a personalized regime makes sense, as every body has individual needs. These lifestyle interventions are often called the pillars of longevity:

• Regular exercise
• Optimized nutrition
• Quality sleep 
• Cognitive engagement
• Stress reduction
• Social connections

In today’s world, modern lifestyles, such as poor diet and lack of physical activity, increase the risk of chronic diseases. 

Advances in preventative Longevity medicine

Spotting and addressing aging-related health issues early has become easier thanks to modern technologies and personalized medicine. Wearable devices, advanced testing, and tailored health strategies are changing how we monitor and prevent health problems. 

The use of wearable data (like CGM, Smartwatches) provides valuable insights into your body and its reactions and helps to craft targeted interventions. 

Additional medical diagnostics (like blood tests, DNA risk tests, body composition tests, VO2 max tests and many more) give a holistic view of your body’s state of health and reveal your individual risk profile.  

When combining all the information we collected, we are able to provide you with very individualized and tailored strategies to improve your health and your longevity. Not just one-fits-all but pinpointing your personal needs. 

With this kind of information you can implement small lifestyle changes with the biggest impact on your body and even enhance the impact with the use of targeted, additional, innovative treatments for best results. 

Conclusion

The future of healthcare lies in shifting from reactive treatments to preventative medicine and proactive healthcare. Instead of waiting for diseases to develop, advances in technology and personalized medicine allow individuals to monitor and manage their health more effectively. 

Wearable devices track key metrics like heart rate and blood glucose, providing real-time feedback to guide healthier lifestyle choices. This data should be combined with advanced medical diagnostics. The amount of information can be overwhelming or difficult to interpret at times.  

AYUN’s experts can help you interpret your unique results and create a personalized plan to optimize your health. 

By focusing on prevention, we can reduce the risk of the most common diseases—such as heart disease, cancer, and diabetes—while improving both the quality and duration of life. This proactive approach empowers individuals to take control of their health and helps ensure longer, healthier lives.

Preventative medicine is not just about living longer, but about living better.

Treat yourself to a longer and healthier life.
