This is a tricky situation because it is such a sensitive topic. It is important not to jump to the conclusion that this girl has an eating disorder. Alot of people have fast metabolisms and may just be naturally slim. In fact, I know of people who get frustrated because they are unable to gain weight. For some people, that is as much a struggle for them as it may be for someone trying to LOSE weight.

However, if she is suffering from an eating disorder it is important to understand the main features of Anorexia Nervosa and Bulimia Nervosa.

Anorexia Nervosa and Bulimia Nervose are eating disorders where the person has an excessive desire to remain thin and to control body shape and weight. People with Anorexia Nervosa usually deny they have any problem and will often disuise an emaciated appearance by wearing loose fitting or bulky clothes.

On the other hand those with Bulimia Nervosa often realise they have a problem with eating, but unlike Anorexia Nervosa, which is a very visible condition to others, Bulimia Nervosa is often disguised and kept secret for a long time. Some people can have symptoms of both disorders.

Here are some ways in which you could maybe go about helping your friend:

1. Step 1

   Learn about the signs and symptoms of anorexia nervosa so that you can identify them properly. However, be careful not to overgeneralize, make assumptions or categorize a person.

2. Step 2

   Recognize that anorexia can be life-threatening and should not be considered "just a phase." It is estimated that 10 percent of anorexic cases are fatal.

3. Step 3

   Listen with understanding, respect and sensitivity. The person probably needs your attention and support more than she would like to admit.

4. Step 4

   Be persistent and consistent in your approach. Be firm, but kind. Tough love is better than no love.

5. Step 5

   Be available to the person and let her know that you are there to help. A person with anorexia may not want to talk immediately, but after reflection on the problem, she may want to come back to you.

6. Step 6

   Accompany the person to the doctor or help her make the initial phone call for help.

7. Step 7

   Share your own struggles without dominating a conversation. Create a safe environment to share sensitive emotions by actively listening to the person.

8. Step 8

   Research a list of available resources for the person to seek professional advice. Talk to the nurses in CIT Medical Centre or someone from the Counselling Centre.

9. Step 9

   Make sure you have a place to get support for yourself; helping someone else can be emotionally draining. You will need support from both friends and professionals who are experienced in eating disorder intervention.

Remember, this girl may not have an eating disorder. But by spending time with her and befriending her, you may learn more about her. You could even forge a lifetime friendship. The important thing is that you obviously care enough about her to ask this question and I applaud you for that. :)
