Most people hear “doctor” and picture someone fixing you after you’re already sick. That’s medicine, and it’s huge. But public health is the other half, and it honestly doesn’t get enough credit. Public health focuses on keeping whole groups of people from getting sick in the first place. It focuses on clean water, vaccines, safe food, not smoking, catching stuff early.
Here’s the part that made it click for me. When you look at what actually kills people, it’s not random freak accidents most of the time. According to the World Health Organization, 7 of the 10 leading causes of death in the world are noncommunicable diseases like heart disease, stroke, and diabetes, with heart disease at number one. Most of these are very preventable if people were more aware, which is wild to me. We mostly die from slow stuff we could’ve gotten ahead of.
Let me put it in basketball terms. Everybody hypes the player dropping 40 points (the surgeon, the hospital). But defense is what actually wins championships, and nobody films a highlight reel of a good box-out. Public health is the defense, as it is quiet, not flashy, and stops the problem before it ever reaches the hoop. Public health is the less-known defense in keeping people healthy.
My grandmother is a big reason I started caring about any of this. She smoked for years and passed away from pancreatic cancer. Losing her made me want to understand the “before” part of getting sick, not just the “after.”
Bottom line: Public health is playing defense for an entire population, and defense wins.
