Dizziness,Lightheadedness,headaches,vertigo anyone???

I've been struggling with all of the above for about 7 years now. It's been a chronic problem and I have yet to find a Dr. that can find out the cause. My theory is that it is heart/BP related and maybe weight related. For the FIRST time in my life, the doctors have NOT blamed my weight, but speculate that it may be a possibility. Has anyone had similar problems? Do they get better or go away completely after weight loss??? I'm hoping so, it has been extremely hard to cope with and difficult functioning day to day. Atleast I quit as a result of it, 7 years smoke-free. Now working on the weight issue. Still waiting for word from UHC. Dr submitted papers Dec. 1st......I think I'll call and bug them again!
