I'm Type 1, and I lost a lot of weight in the months before my diagnosis. I'm typically around 165lbs, but went down to around 130lbs before going to the doctor. I knew I had been losing weight, but had no idea it was that much. Gained it all back pretty quickly after getting on insulin.
Who here is on a pump? I'm considering switching to a pump once I get on new insurance when I start my new job in a month or so. I've been on injections with Humalog/Levemir (and Novolog/Lantus for awhile), but would like to see how much a pump could help me with my control. My A1C is pretty low, but I think it's been thrown off the last couple of times from having too many lows.
Been on a pump for ~16 years(Medtronic). It makes ALL the difference in the world IMO, especially if you start pumping right away(so you don't get bad habits).
If you've got an active lifestyle/want the best control, then it's a no-brainer.
My advice: if you do do it, buy this book, http://www.amazon.com/dp/B009NNKZKA/?tag=neogaf0e-20. Edition doesn't matter so much, as the differences will mostly be with available pump manufacturers, but the book itself is INCREDIBLY helpful at the start.
Also, try and get a week or so trial with a CGM(continuous glucose monitor) at the start/fairly soon. That way, you will have a good baseline for how your body acts and will help you get in target quicker.
As far as losing weight goes: yea, when I was newly diagnosed, I had lost something like ~30 lbs...and I was a pretty skinny 12 year old at the time...so you can imagine what -30 lbs would look like. My parents were freaking out and I just felt like shit in general. Pretty remarkable though, how the human body can bounce back like that. Within a month or two I was back near my normal weight and feeling fine again after being on insulin/the pump.
And hey, if you get a pump, you can always make bionic man jokes with the ladies.
