<p>Renee,
I am sympathetic to your daughter and am glad she is being monitored by a doctor. </p>
<p>I have struggled with being underweight all my life–I also used to run track in school, and that helped me gain weight. I have often been called anorexic, and I see that, according to this table, with a BMI of 17, I am ;)</p>
<p>BMI Categories </p>
<p>15 or less = Starvation<br>
15.1-17.4 = Anorexic<br>
17.5 - 18.4 = Underweight<br>
18.5 - 24.9 = Ideal<br>
25-29.9 = Overweight<br>
30 - 39.9 = Obesity<br>
40 or greater = Morbidly Obese</p>
