Modern medicine has never been better at keeping people alive. So why are we spending more of our lives unwell?
In this episode of The Mind-Gut Conversation, Dr. Emeran Mayer examines a new analysis from the Global Burden of Disease project, published in Lancet Public Health, comparing how long people live with how many of those years are lived in good health across 204 countries and territories.
The difference between those two numbers is called the morbidity gap. In 1990 the average person could expect to spend 8.8 years of life in poor health. By 2023 that had risen to 10.7 years, and the gap widened in 203 of the 204 places studied. The wealthiest countries fare worst of all, with the United States leading globally at 14 years.
Dr. Mayer explains what is actually driving those unhealthy years, why the trend now extends across the entire adult lifespan rather than clustering in old age, and why two of the largest contributors sit squarely within the brain-gut-microbiome system.
Topics discussed include:
• What the morbidity gap is and how it is measured
• Why the 45-year-old compression of morbidity hypothesis is being challenged
• Why high-income countries carry the largest health gaps
• The five conditions responsible for most unhealthy years worldwide
• Why health decline is starting in middle age
• The gender health paradox
• Why years lived may be the wrong scoreboard
This is a science-driven discussion for anyone interested in healthspan, healthy aging, and chronic disease prevention.
