For most of human history, medicine had one overriding mission: to keep people alive. The great victories of modern healthcare were measured in lives saved, children who survived infections that once killed them, or cancer patients whose diagnoses were transformed from death sentences into manageable conditions, as slowly but steadily people began living longer than any previous generation. But that success created a new medical dilemma: What happens after survival? A person may live into their 80s or 90s, but those additional years are not always healthy.
For millions, the final chapter of life is marked by chronic illness, declining mobility, cognitive deterioration and a gradual loss of independence. The challenge facing modern medicine is therefore no longer simply adding years to life; it is ensuring that those years remain meaningful. That question lies at the heart of one of healthcare's fastest-growing fields: longevity medicine. In Israel, Meuhedet Health Services is launching a comprehensive longevity program based on the premise that the future of medicine lies in identifying risk before disease appears.
"The real question isn't how long we'll live, but how we'll live those years," says Dr. Sivan Berger Achituv, who heads Meuhedet's longevity initiative. The distinction between these two questions, lifespan versus health span, is the foundation of the entire field. "Longevity, if you go back to the Latin roots of the word, simply means long life," Dr. Berger Achituv explains. "But we're not trying to extend life expectancy for its own sake; what we're really trying to extend is the number of healthy years people enjoy."
The science of aging has made incredible strides in recent years, drastically improving our understanding of how our cells and bodily systems age. This research now allows us to better assess an individual's unique risk factors, offering personalized recommendations to protect health before disease or decline can take hold.
Today, developed countries are experiencing a dramatic demographic transformation, as populations are aging, and with age comes a greater prevalence of chronic disease. "As populations age, we see higher rates of chronic illness," Dr. Berger Achituv notes. "We see loss of muscle mass, metabolic disorders, declining physical and cognitive function, and higher rates of cancer."
The challenge is that medicine has become better at extending life than at protecting the quality of those added years. "Today there is roughly a ten-year gap between average life expectancy and healthy life expectancy; healthy life expectancy refers to the years when people remain functionally independent and have a good quality of life." Dr. Berger Achituv says, a gap that carries a heavy price. "If the average gap is ten years, many people spend a significant part of their later lives dealing with disease. It's a tremendous burden, for patients, for their families, and for the healthcare system." And this is where longevity medicine enters the picture.
Preventive medicine is already a major part of community healthcare and medical personnel have long encouraged patients to exercise, eat well, stop smoking, and maintain healthy habits, but those recommendations were largely universal. The new approach aims to better assess individual risk factors and tailor personalized recommendations to bridge the gap.
Instead of waiting for warning signs to become diseases, physicians can examine a person's individual risk profile: muscle strength, body composition, cardiovascular risk, metabolic markers sleep patterns and lifestyle factors. "The goal is not to wait until disease develops," she says. "The goal is to identify risk factors much earlier and either prevent disease or delay its appearance."
A shift made possible by the scientific study of aging itself, that is, the field of geroscience, which examines the biological mechanisms behind aging. "We're learning much more about the processes that cause cells and body systems to age," Dr. Berger Achituv says. "The better we understand those processes, the better we can improve outcomes."
Yet as interest in longevity has grown, so too has the commercial industry surrounding it, with the word itself becoming almost unavoidable, appearing everywhere from wellness products to cosmetic treatments. Dr. Berger Achituv believes that this requires caution. "The term has become extremely trendy," she asserts. "You see multiple supplements, various injections and products that promise dramatic results at extending life. People need to be careful. Not everything sold as a longevity solution is scientifically proven and safe".
The difference, she argues, is that medical longevity is not about chasing eternal youth, it is about preserving function. "We're not promising to stop aging. We're certainly not promising that everyone will live to 120. We're offering a structured medical process." That process reflects a broader understanding that aging is not controlled by a single factor. The body does not decline one system at a time; everything is connected.
"We're trying to understand the whole person," Dr. Berger Achituv says. "Nutrition, fitness, endurance, strength, balance, resilience and sleep, all of these things are connected." That philosophy is reflected in Meuhedet's new program, in which participants complete detailed digital questionnaires that assess lifestyle, sleep, nutrition, family history, resilience, menopause and women's health and other risk factors. They undergo laboratory assessments and physical evaluations, including measurements of body composition, cardiovascular health, maximal aerobic capacity, muscle strength and balance, with a multidisciplinary team, including physicians, dietitians, physiotherapists and nurses, who then build a personalized plan.
The program initially focuses on adults aged 40 to 65, a stage of life when many health risks remain preventable or reversible. "The goal is to help people reach older age with greater functional reserve," Berger Achituv says. "With better aerobic fitness, stronger muscles, healthier bones and better nutritional status."
Perhaps the most significant part of the initiative, however, is not technological, it is social. Until recently, longevity assessments and personalized prevention programs were largely available through private clinics, often at considerable cost. By bringing the approach into a public healthcare framework, Meuhedet is attempting to redefine who has access to the medicine of the future. The underlying idea is simple: if prevention is truly the future of healthcare, it cannot remain a luxury product.
For Dr. Berger Achituv, the goals ultimately is personal responsibility without blame. "About half of the aging process is determined by genetics," she says. "We cannot change that." But genetics is not destiny. "We have a significant influence over our health," she says. "We have much more power in our hands than people often realize. Our goal is not simply to help people live longer," Dr. Berger Achituv concludes. "It's to help them arrive at old age stronger, healthier and able to continue living the lives they want."
