I also suffer from central obesity, have striae in abdominal area, hirsutism and slightly increased testosterone and
low transferrin. The low transferrin worries me because I remember being 10 years old and having a depression on my thumb nail. I had no idea what is was and I now think it could of been koilonychia. I am also always cold and I went to donate blood at 23 yr. old, and a needle stick to test for iron was given to me. I was told I had low Fe and could not give blood at that time.
