If you are shorter than 4'10'' adult height (Jodi is like literally the cutoff point) you scientifically suffer from "Dwarfism." Now whether that comes along with a constellation of other issues like disproportionate limbs, or other abnormalities seen in midgets/dwarfs, points to a bigger issues. I know a girl who is under the cutoff, and her proportions are only slightly off, but she still looks normal by all accounts other than height.
