Kaitie, don't let him take away the pride you have in your accomplishment! Bad doctor for doing that! I HATE IT when they do that!!! Are you afraid he's not listening to you? Because sometimes, they just want to toss pills at us because it can be easier to treat something with pills than it is to have someone change how they live.
Having said that, the point of the metformin, in the long term, is to save your pancreas. Because when it's done working, there's not much they can do (yet) to bring it back so that it is doing it's job. Your pancreas is still working, but just not as good as you want it to. Weighing more put it through it's paces, but you may be genetically predisposed to type 2 diabetes and over time, the potential was there for your pancreas to eventually not be able to keep up with you. I know thin people, people who have never ever been overweight, who have to deal with type 2 diabetes. Something just put their pancreas over the edge. And for you, just because your doctor makes it sound like your weight is the cause, it may very well not be the cause.
You don't like the idea of taking the metformin (I certainly don't like it, and my body felt really horrible when I was on it), but you might still have to take it. You've got two weeks to make some changes. And changes can be made. You can manage your blood sugar better with diet and exercise. It takes quite a bit of focus and perhaps changing a lot of what you eat. It's more than what you do for simply losing weight. You can cut out all starchy forms of carbohydrates, and all forms of sugar. You can make sure you don't overeat proteins. You can eat plenty of healthy fats. Basically, a ketogenic diet. And you can exercise effectively, with some cardio and a good bit of weight training, on a daily basis. There are things you can do for yourself over the next two weeks and you see positive results when you go in for further tests.
Be braced to hear your doctor talk more about losing weight. How much are you really going to lose in the next two weeks? Not that much. He know that! But he's going to focus on that. He can't help himself. It's what he's trained to do.
You might consider looking at the
work of Dr. Bernstein, and participating in his forums. I found it very informative and helpful. It has worked for me so far.
