What if one of the biggest mistakes in modern healthcare is that we wait until people are sick before we start talking about health?
Every day, doctors save lives with medications, operations, scans and emergency treatments. Modern medicine is extraordinary at responding to crises. But there is a question that has become increasingly difficult to ignore: what if many of those crises could have been prevented decades earlier?
In this video, I explore the uncomfortable gap between treating disease and preventing it. We'll look at why heart attacks, type 2 diabetes, dementia and many other chronic diseases often develop silently over decades, why prevention struggles to compete with treatment inside modern healthcare systems, and why some of the most powerful health interventions rarely involve a prescription pad.
We'll also discuss the realities of frontline medicine, the pressures facing doctors, the incentives that shape healthcare, and why lifestyle, nutrition, movement, sleep and metabolic health deserve a much bigger place in the conversation than they currently receive.
What you'll learn:
-Why chronic disease often begins decades before symptoms appear
-The difference between prevention and treatment
-Why healthcare systems are designed around reacting to illness
-The challenges doctors face when discussing lifestyle change
-What drives heart disease, type 2 diabetes and metabolic dysfunction
-Why prevention receives less attention than treatment
-The role of nutrition, exercise and sleep in long-term health
-How to take ownership of your health before disease develops
