Double Scoliosis, also twisted badly. I think I should still use my former height in figuring my BMI, and not my current height, because I cannot stand up straight. I used the site I mentioned, and it said I was Overweight when I used current height. But it said Healthy Weight when I used my former height. Confusing!
