Just some thoughts. As a PA (physician assistant) it sounds like you may have what they call metabolic syndrome. Your primary risk factor for this is abdominal obesity. I see this all the time in my practice and am working very hard to prevent/reverse the effects of it.
Essentially its a constellation of problems that work hand in hand to increase your risk for heart attack and stroke. They are
(essentially good cholesterol), and of course usually high cholesterol may go with this but not always.
(fat in your blood)
elevated blood sugar
elevated blood pressure
Use to be called Syndrome X years ago and some docs don't believe or accept this as an actual syndrome. However, I see this over and over and can state from my experience it exists.
There are two primary factors that cause it. Poor dietary habits and being sedentary.
Kevin is right in that you should very much concentrate on your nutrition. Your exercise is plugged in for you mostly via this web site (aka simplefit). Eating is a little tougher cause its hard to tell someone, "Eat exactly this and this amount per day." In your case, being a diabetic, it is absolutely essential that you get control of what you eat.
As we all know thats easier said than done. If you look at the various categories on this site you will see that nutrition and diet logging are the least accessed. This is actually quite common (I'm guilty too heh). But it is equally as important as getting fit. Doing your homework on this one will pay back in huge dividends later.
I would also recommend a book written by Dr. Stephen Masley. It's called "Ten Years Younger". He has been studying this syndrome for a long time and has a pretty good handle on it. You can also visit his web site at http://www.tenyearsyounger.net
(I get no royalties for referring you to him [I swear!])
If you haven't already done so I would get an appointment to see a DIABETIC
I would also suggest that you get regular follow up with your Physician checking your blood sugar often (maybe even checking at home with a glucose monitor). Maybe quarterly get a hemoglibin A1c done to verify your on track. If it's high it means your not keeping it in control.
The good news is that you may actually be able to reverse this with a little time, dedication, and motivation. So glad your here and I wish you well in your endeavors. You have a good group of people to help you along.
ps. sorry to get long winded. I really get into this stuff hehehe.
