Anorexia is defined as not eating. It is, itself, a symptom.

Anorexia Nervosa, the mental condition, is when you refuse to eat in order to lose weight.

not eating, vomitting after eating, thinking you are fat when you are under weight. taking laxatives to lose weight. excessive exercise

it varies, but

if you aren't fat, (and possibly know this) and look in the mirror and think, i'm so fat
not eating, saying your not hungry when you are, obsessing over certain parts of your body, feeling insecure, worrying about your weight

if you think you have anorexia, you need to talk to someone.

when you stand next to a pine tree sapling and noone can see you, you might be anorexic.

If you are standing on one leg and someone hangs their coat on your head, you might be anorexic.

If you eat one potato chip and then say, "oh, I'm stuffed!", you might be anorexic.

OK, I'm done.

The symptoms of anorexia nervosa are:

–Having an intense fear of gaining weight.
–Restricting food or types of food, such as food that contains any kind of fat or sugar.
–Weighing less than 85% of your expected body weight. (In a child or teen, losing or not gaining weight during a growth spurt is a concern.)
–Seeing your body as overweight, even though you are underweight.
–Overexercising.
–Being secretive around food and not seeing or wanting to talk about having a problem with eating.

I hope you don't have this. I've known a couple of girls who went through this and the thing was they were absolutely beautiful girls! Just for some reason in their mind they felt they were too fat. these girls were both athletes with very well toned bodies. I wished they would have come to me I could have saved them from going through what they did. They're fine now but seeing them so thin was scary! I bet you look just fine.

Anorexia is an eating disorder where people starve themselves. Anorexia usually begins in young people around the onset of puberty. Individuals suffering from anorexia have extreme weight loss. Weight loss is usually 15% below the person's normal body weight. People suffering from anorexia are very skinny but are convinced that they are overweight. Weight loss is obtained by many ways. some of the common techniques used are excessive exercise, intake of laxatives and not eating.
Anorexics have an intense fear of becoming fat. their dieting habits develop from this fear. Anorexia mainly affects adolescent girls.
People with anorexia continue to think they are overweight even after they become extremely thin, are very ill or near death. often they will develop strange eating habits such as refusing to eat in front of other people. sometimes the individuals will prepare big meals for others while refusing to eat any of it.
the disorder is thought to be most common among people of higher socioeconomic classes and people involved in activities where thinness is especially looked upon, such as dancing, theater, and distance running.

Hope this helped!

1) People keep telling you you're too thin but you don't believe them or you think they're just jealous.
2) you wish it wasn't necessary to eat to live, or that you could just take a pill instead. if you do eat, you wish you hadn't, or you have special rituals that surround eating.
3) Your clothes size keeps getting smaller, and/or you start layering on more than 2 layers.
4) you are always cold.
5) Your skin is loose. if you pinch up some on your forearm and you can get it to pull up more than 1/2 an inch it's loose.
6) Late stages, your hair starts to get thin and may start to fall out.
7) the parts on you that look biggest are your shoulders, elbows, wrists, hips, knees, and ankles.
you think you are fat.
9) you never stop trying to get thinner.
10) try this test. take a string and tie two ends together into a circle that you think is about the size of your hips. place this on the floor and make it oval. Step in and pull it up around your hips. It might surprise you!
