It could be worse, but you certainly don't want it to stay that high. Dropping the flab and adding cardio will almost certainly help some, but you may be one who needs a bit of medicine to keep it in check. I'm not a doctor, of course. Be sure you see one.
I agree with MnB as well...It's time to lose some of that goo you're packing around, and learn to eat clean. As far as supps go I've read that niacin (B3) is good for this condition, and NO2 supps have been shown to help with increased nitric oxide production thus assisting with vascular diseases like hardening of the arteries.
Get on the internet and do some research on these and other supps as well as learn all you can about high BP, and never just let any Dr have the final word without you making a concious effort to understand what is going on.
