Alright kiddo, so you know how sometimes women have a special place inside their belly called the uterus where a baby can grow if they decide to have one? Well, sometimes that uterus can cause problems and make the woman feel really uncomfortable.
One way to help this is to do something called endometrial ablation. What that means is that the doctors use special tools to remove the lining of the uterus (the part that gets thick when a woman is getting ready to have a baby). They do this because that lining is what makes the woman bleed when she has her period, and sometimes that can be too much or too painful.
After they take out the lining, it won't grow back, so the woman won't have her period anymore. This can be a good thing because it means she won't have to wear pads or tampons, and she won't have to deal with those cramps or other uncomfortable symptoms anymore.
Now, this isn't something that's done all the time, and it's not for everyone. The doctors will talk to the woman and make sure it's safe and the right thing to do. But for some women, it's just what they need to feel better and be more comfortable.
