is my sister anorexic?

Depends on her habits, does she eat only negative calorie foods? Does she drink tons of water/coffee/zero calorie drinks. Does she exercise all the time? Does she avoid eating or eats alone in her room?

You need to pay attn to her habits, and check some pro-ana web sites to see if she's doing some of the tips that they have on there.

That kind of thing happened to my friend, except that it was while I was gone, she became annorexic.

First of all, has she always gone running in the morning? because if she'd just started during those two weeks then it's probably from the running.

Secondly, IF she's annorexic, DO NOT ask her; either way she'll deny it. What I would do is just watch her for a few days, eat meals with her and just take in her reactions to food (and make sure she's not in the bathroom for a long time).

Just spend a lot of time with her, and if what you're seeing worries you, if she's not acting herself, then I would assume she needs help.

If she us making herself vomit and/or takes lots of laxatives she would probably be Bulimic. Anorexia is when you starve yourself and just will not eat. But if she is bingeing and purging, she would be bulimic. Chances are she would be both. Usually they will do both and go from one extreme to the other.. If you think she is, please try and help her by talking to her. Let her know you can and remind her of how serious this is.. She could do so much damage to her body It could ruin her for life. It can cause her teeth to rot and lieterally fall our. Not to mention it could even prevent her from having children. Let her know you want to help her. But, if she is in denial or refuses to discuss this with you or let you help her, then you need to find out if your parents are aware of what is going on. They need to know, even if it means your sister getting upset with you. This may be the only was you can get her help is by talking to your parents and telling them your concerns. This can be and is a very serious illness. It is nothing to take lightly. If she does this frequently, let her know that she cannot be having have stomach problems every day unless something is wrong. If she still denies the problem and continue to have the "upset stomach" frequently she would need to see a doctor. In either case there is obviously something wrong with her.

you might want to watch her weight carefully for a while before you make assumptions.

maybe at the summer school she didn't get to eat like she normally does, and therefore lost the weight.

if she doesn't gain some back, you might want to check she's okay, but don't accuse her of being anorexic.

i say yes because i have been runnning for 1 month and i have only lost 15 pounds and to lose a lot in 2 weeks that ahs to be a posibility

ask her. you mentioned some thing about summer school. maybe she just under a lot of stress. if all else fails do an intervention with other people and save her life.

If she has bad eating habits, depression, and u can see her bones. Those are signs of anerexia. If she just lost some pounds running, i would worry about it.

it could be...you probably might want to talk to her. but don't be accusing, just ask her if everything's alright and let her know if there's anything she needs to talk about your there and you care...you don't want her to get on the defensive and people with eating disorders tend to get very defensive.

It is best you ask her and if she will not tell you ask her to see a doctor for some tests.

i dont think so maybe she is into fitness
