Okay, so our bodies make things called steroids. These are like special chemicals that help our bodies do different things, like grow and stay healthy. But sometimes our bodies can't make these steroids correctly - this is called an inborn error of steroid metabolism.
To understand what this means, think of making a cake. Normally, we follow a recipe to make a delicious cake. But imagine if we had the wrong recipe or didn't have all the ingredients we need to make the cake. The cake wouldn't turn out right, or it might not even be edible.
Our bodies work like this too. If we don't have all the things we need to make steroids, they might not be made correctly or they might not work right in our bodies. This can cause problems like not growing like we should, not having enough energy, or even getting sick.
So, inborn errors of steroid metabolism mean that our bodies have a problem making or using steroids correctly. But don't worry, doctors can help figure out what's going on and give us special treatments to help fix the problem.
