I know the meaning of eating disorder:
Eating disorder - Wikipedia, the free encyclopedia
But my question is: Can the expression eating disease be used with the same meaning? If not, is the expression eating disease used in English, what does it mean?
PS Feel free to correct any mistakes in this post
You could have a disease which makes eating difficult, such as if you have an infection in the throat. The infection is the disease, and it becomes difficult to eat because it hurts.
If you have a cancer of the throat, you might not be able to eat at all in a normal way, the cancer is the disease.
An eating disorder is something in your brain which causes you to have problems with eating.
