Can you really determine a cause of an eating disorder? I know A person can have pre exsisting condition that can assist them. like depression and other feelings and emotions that go hand in hand. Does anyone have any ideas as to what can be a "cause"??? I dont have an eating disorder, its a question my wife has for a class and she was unsure of it. media and genes both affect the person it depend though sometimes it can be triggerd by something as common as strep so it really depends on the history and the people around the person. Some times it can be a chemical in balance, but there is more to it than that, you need to go and talk to a doctor and get help |
