Anorexia Recovery & Treatment

k so im writing a paper on anorexia and i keep seeing that its more predominate among females… does anyone know why this is?

I’m a 13 year old boy and am trying to recover from anorexia. I am currently 5′6 and 83lbs (down from 120). I want to gain some weight back because my doctor threatened to place me back in the E.R if I do not become healthier. I was wondering if I do eat regularly will I get to a ideal weight for my height then stop gaining and pretty much stay there?

I was reading about nutrients and the bad effects of too much and too little, and it said too much calcium, among other problems, can cause anorexia. Why?
