Can someone who has an eating disorder be forced to see a psychiatrist?

Or anything else of that sort, against their will?

They can be considered unfit and unable to take care of themselves. Eating disorders are mental illnesses, so this would qualify for involuntary treatment, but the legal threshold for doing this is fairly high. It would be considered a deprivation of liberty rights.

If you've been certified unfit to care for yourself, then yes.
Sure. If you are a danger to yourself. You can be restrained and they can put a feeding tube in you.
Sure it's possible to force them into seeing a psychiatrist, but most likely they aren't going to listen. The best thing to do for a person with an eating disorder is to get their mind off of food. Get their mind off of always thinking about how they can stay thin or what they can eat. It's an obsession and people with eating disorders are not going to quit until they are ready. It's kind of like dealing with alcoholics or people who smoke. I've heard that eating disorders never go away. No matter how much healthier the person becomes, they will always have this issue to deal with.
Considered unfit, insane or other mental disorders or if a minor.
If the courts say so. Or your doctor. So which one are you. Over eater or anorexia.?
asking.
