Cachexia

Okay kiddo, so cachexia is when someone's body gets very weak and sickly because they are not eating enough food. When people have cachexia, their bodies start breaking down but not just the fats and sugars in their body, but also important things like muscles and organs. This can happen because they have a disease or are going through a really tough time like cancer, and the body has to use all of its energy to fight the disease instead of growing and staying healthy. So, even if they do eat food, it doesn't help because their body is already so weak. It's like trying to repair a car that's already broken down completely. That's why it's important for doctors to identify cachexia early and find ways to help the person eat and get better nutrients to fight their disease.
