What are non-infectious diseases?

Non-infectious diseases are health problems that don’t spread from person to person like a cold or flu.

Imagine your favorite toy, let’s say it’s a robot. If the robot breaks, it might be because of how it was made or how you used it over time. Non-infectious diseases are kind of like that broken robot. They happen inside your body and aren’t caused by germs that jump from one person to another.

How they work

Some non-infectious diseases come from things we do every day, like eating too much candy or not moving enough. Others can be from how our bodies grow or change, like when your bones get weaker as you age.

Examples around the house

  • Diabetes is like a traffic jam in your body that happens when sugar levels get too high.
  • Heart disease is like a clogged hose, your heart has to work harder to push blood through, just like water through a dirty pipe.

These diseases are long-term and can be managed with healthy habits, just like fixing your toy robot with new parts.
