Lol at this, as if the doctor isn't going to take one look at her visible chest bones and calculate her BMI to determine she's underweight for her age. She's such a a smug retard. That plus she already said her mom knows she spits food out into the toilet to avoid eating which will no doubt be brought up. Doctor's aren't stupid like you, Mary.
Her BMI is around 18.1 assuming she's 99 pounds like she claimed before (or 17.5, she has claimed to be both 5'2 and 5'3, wouldn't be surprised if she lies about being shorter than she is because she looks around the same height as her mom) While not life threatening, it still is not a healthy weight and she wants to lose even more.
