Eating disorder....?

My friend has recently went from 160 pounds to 130 pounds. She was on a diet, I know 130 pounds is ok for someone who is 5'7'' but her stomach is flat and her hip bones stick out and her collar bones. She still wants to lose more wieght. Does she sound aneroxic to you?

Not really. How fast did she lose it? If it was in a month, yes, that could be an eating disorder. If it was over a year, then no, that's healthy. If she is bony that's just not enough muscle. she needs to get toned at the gym.

No.
Don't bud in unless it gets real serious, but maybe keep an eye on her.

She has some type of eating/psychological disorder.

It could be a developing case of Aneroxia Nervosa. It's impossible
to say for sure without some testing--which, of course, can only be
done by a doctor.
I'd suggest you have your friend get a medical check-up, a.s.a.p.

Good luck.

Sounds like it. But then again maybe not. If she has lost a ton of weight in the past month or so then yes. The average person on a healthy diet only loses about 2-3 lbs a week!
So i guess that's up to you to see and find out if she refuses to eat at places, or get's even more skinnier.
If you think she does, just tell her you're worried and would like to know if she has an eating disorder. Do this calmly! (or she will think you aren't going to believe her response)
And if she says yes, give her some help and advice.
Just don't blow things out of proportion! She'll get mad and upset if you do that. Eating disorders are like a life style for some people. If you tell them to stop cold turkey, they'll flip and think you don't understand. It's all in their head.
