Hi there, congrats on your decision to move forward with WLS and welcome to the forum!
Phillygirl gave you some great advice and information! Adding to that. . . . . you questioned RNY or sleeve for diabetes control. . .RNY or DS (duodenal switch) both cause metabolic changes with your GLP-1 that affect the changes in your diabetes. The sleeve does not, so though the sleeve would certainly assist you in weight loss, it would not metabolically assist you with putting your diabetes into remission. I would suggest discussing this in depth with your surgeon.
I'm a Type 2 diabetic for 6 years now, got the LapBand in 2006, lost 100 lbs, off meds IMMEDIATELY after surgery, and diabetes in remission until 2008 when I had plastic surgery, developed horrendous acid reflux and had to have my band unfilled. Re-gain of 50 lbs and diabetes back with a vengence, way worse than before. Finally, 4 weeks ago I was able to have my LapBand removed and revised to a RNY.
Now, I am down 29 lbs and off Metformin XR, but still taking daily Victoza shots. However, my sugars have dropped from 280-300+ (fasting) to an average of 123-145 (fasting). As you can see, my diabetes did not immediately go into remission this time; however, look how fast my numbers have come down! I am hoping that in a few more weeks, I will be off of the Victoza too, and my diabetes will be strictly diet-controlled and back in remission.
One of the things discussed at our support group was how some insurance companies are now covering diabetics with a BMI of as low as 35 to have RNY to put their diabetes in remission. Apparently there are also talks going on to even lower the BMI range to allow more diabetics to have the surgery in the future. How amazing is it, that although it is not a "cure", having this surgery could potentially put diabetes into remission for thousands and thousands of people?!?!? I can't even wrap my head around how many lives could be saved.
I just put some pics up on my profile, and have a few blogs about how my surgery went, you are welcome to take a look if you are interested, or you can message me directly if you would like.
Best of luck to you!!!!
