i have a BMI of 13.3 considered to be life-threatening, AMA

my condition is not related to mental health and my body image nor is it self-induced. above all, it is NOT something to aim for.

i'm a 16 year old & 10 month girl and i weigh about 79.8 pounds at 65 inches tall. the heaviest i have ever been was around 84 pounds, and at my most recent low point i weighed 77.

i have never been hospitalized for my weight, i have been extremely skinny my whole life. none of my organs have shown signs of failure, my hair is healthy, i do not skip menstrual cycles, and i go to school 5 days per week without my weight getting in the way. somehow i don't even look that emaciated.

i eat as much as i can, 3 meals a day plus snacks. i have ARFID though so it's difficult

there are other physical issues such as hEDS, POTS, and pectus excavatum (i call it the Dent) that prevent me from being active.

before anyone gets skeptical and does the calculations, i am aware that i'm at the 0.00003rd percentile for my demographic. i am quite a statistical anomaly which is actually annoying because my doctors have no idea what they are doing with me.

i figure i've adapted to this weight in some way if i can function at the level that i do.
