About 7 or 8 years ago, I decided to start trying to lose weight by “not eating so damned much”. And, pleasant surprise, it worked! I dropped 2 pants sizes over the course of a couple of years.
But, then, I started to noticed other things…
I was thirsty all the time. This was my first real warning sign, and I was immediately reminded of an episode of “MAS*H”, in which a chopper pilot was hiding his diabetes, because he didn’t want to be grounded (and constant thirst was one of his symptoms). It undoubtedly didn’t help that I was frequently trying to satisfy that thirst with regular soda…on a typical day, I’d guess I was drinking the equivalent of 6 to 8 cans of Pepsi a day. (In retrospect: yikes!)
In early 2005, I was feeling good, I was looking good (no longer overweight), and was totally in denial over this thirst thing. Then, my feet started to hurt. I’ve had arthritis for all of my adult life, so, at first, that’s what I thought it was, but taking pain relievers didn’t really do anything for the pain.
By the summer of 2005, I was starting to get concerned. The pain in my feet was nearly constant, and I now noticed that my breath had a funny odor. Also, my blood pressure (when I’d take it at the self-service kiosk at the drug store) was elevated. I was also spending way too much time on WebMD, trying to self-diagnose. 
Finally, I went to a doctor, for the first time in 6 years. First thing he does is weigh me. I hadn’t weighed myself in a long while, but I was stunned to learn that I was about 20 pounds lighter than I thought I was! Then, he took my BP, which was something like 160/100. He asked me, “do you have any pain or tightness in your chest?” “Yeah, a little bit.” He sent me to the emergency room, with suspicions of a heart attack.
Well, once I calmed down in the E/R, my BP dropped to 120/80, and the bloodwork and chest X-ray came back negative. They held me overnight for observation, and were about to release me, when the GP stuck his head in my hospital room. “By the way, your blood sugar was like 200. You need to come back for an A1C test.”
I took an A1C a few weeks later, and it came back at 8.8. I had Type II diabetes.
The weight loss was undoubtedly contributed to by the uncontrolled diabetes…and, it made me very lucky, as I didn’t have to lose any additional weight (I have a number of diabetic friends, and most of them are significantly overweight, which doesn’t help at all).
The GP put me on metformin, and didn’t do a whole lot else (it became clear to me that he really didn’t know an awful lot about diabetes). I sought out, and found, a great endocrinologist; I highly, highly recommend that you do the same, if it’s at all an option for you. He put me on Actos as well as metformin; my A1C numbers are now around 5.5 (in my doctor’s words, “the blood of a normal person”).
Lifestyle changes: one of my other issues before the diagnosis was that I was very sedentary. I make a point of exercising most every day now…not a heavy workout, but I try to walk a couple of miles a day, do some light weightlifting, crunches and push-ups, etc. I think that’s made a big difference. I went cold-turkey on regular soda and the like (candy, cookies, etc.), and have tried to cut back on other starchy things (switched to whole-wheat bread, don’t have as many french fries as I used to, etc.)
I’d say that it took a few months for my daily numbers to come under control (my fasting number is now usually right around 100, my after-meal numbers usually 130-140), but feeling like I’m in control of things, and able to make choices that will keep me healthy going forward, has been a great help.
