Frailty syndrome is a condition that can happen to older people when their bodies start to become very weak and they are not as healthy as they used to be. When someone has frailty syndrome, they might have a lot of trouble doing everyday things like walking, getting up from a chair, or even just getting dressed.
Think of your favorite toy that you've had for a long time. When you first got it, it was really strong and worked perfectly. But over time, it might have started to get worn out and not work as well as it used to. That's kind of what happens to our bodies when we age. Sometimes our bodies start to slow down and it becomes harder to do things we used to do easily.
Certain things can make frailty syndrome worse, like not being very physically active or not eating healthy foods. It's important to try to stay healthy as we get older so that we can keep doing the things we love!
