I went to the doctors because I've lost weight unintentionally (not a scary amount and not really fast, but I just wanted to be on the safe side).
My BMI came out at 17.1 which according to BMI classifications is underweight. I thought she was going to say something along the lines of me needing to gain weight but comment was that it was 'the lower end of normal'?
I know BMI isn't the most reliable but even as a guideline, 17.1 seems quite a bit lower than the 18.5 that normally signals being underweight. Is it normal for 20 year old women to have a lower BMI?
