I am a type II diabetic on an insulin pump, and Actos for the last 5 years.
When I started the pre-op diet my wt. was 307 and my basal insulin rate was 3.9 U/hr with boluses to cover carb loads.
On the day of surgery, I was down to 287 and my basal rate was down to 1 U/hr and I am off Actos.
Now on post-op day 5, I am down to 0.6 U/hr of insulin, but then I am essentially in starvation mode for at least a few more days. Wt was 276 today, so I am very pleased. I suspect that the rapid wt. loss,in my case, is due to the decreased insulin use (Insulin is lipogenic.) So far I am very pleased.
BP meds haven't changed yet but I think that will eventually change.
My major motivation to have the surgery was my declining renal function. My nephrologist told me that I would be on dialysis in 2-3 yrs unless I dropped 100 lbs. So I'm on my way.
