Hate to be the bearer of bad news but a fasting glucose of 200 is almost definitely a diabetes diagnosis. In fact, I think it's around 140 that doctors get concerned.
Honestly, I didn't want medicine either. But here's the thing, my body doesn't work anymore. On diet alone, i cannot get my sugar low enough because 2.5 hours after a meal, my liver goes into panic mode and dumps glucose into my system and my BS skyrockets again. This happens no matter what I eat. There is a chance that losing weight will decrease my insulin resistance and it won't be as bad and maybe I can come off the meds. But right now, no, I need metformin to keep my liver from dumping too much glucose. It still does it too much and I might even need a stronger dose (I see my doctor next week to discuss).
Before I was diagnosed and on meds, I was exhausted, starving, and thirsty all the time. No amount of food, water, or sleep alieviated that. In April, I couldn't walk 5 blocks without feeling like I was going to die. Now, I still struggle, but thanks to good care from my doctor, metformin, and a major diet overhaul, I still drink like a camel (at least a gallon a day, I quit measuring) but it's because I want to, not because I need to, but I'm not starving all the time, I have tons of energy, and walked over 4 miles last night, with energy to spare. But it's not just about "right now". Good control NOW means fewer complications down the road. I, for one, don't plan to lose a foot, go blind, or end up on dialysis because I couldn't put down the donuts (God, I miss donuts...) or wouldn't take a little pill every day.
This disease sucks. and managing it sucks even more. But it's the hand I've been dealt and I still want to play.
I do think you should see a doctor. You should know what your a1c is and see what s/he recommends. At this point, I am using just a GP who has phenomenal bedside manner and really cares about her patients.
But in the end, our diabetes management is down to us. You make the choices and every bite you put in your mouth/every step of exercise you take affects your blood sugar and influences potential complications down the road.
I wish you the best of luck. Try www.diabetes.org
forums, too. Folks there aren't as "supportive" as they are here at 3FC but they sure are knowledgable. And forget what the ADA says about dietary guidlines. Seriously, no diabetic can eat that much bread/pasta and expect to keep their blood sugar under control. Low-carb all the way!
