More 5 year history headaches!

I finally get a record of my weight for 2006 and my BMI was 34. Even though it was 35 or greater for the the following years, the Dr's office says I may not be approved . I have not had my height offically taken since 1990 so I'm hoping that I can ask them to officially check my height and that I've shrunk with age age and they will update my records and that will fix the problem. Would love some feedback. Thanks
