…in terms of weight loss, lowering of HgbA1c, and weight-related quality of life. The specific gastric bypass surgery used in the study is the Roux-en-Y version.
Band Gastric Bypass Surgery (not the only type of gastric bypass): very successful at “curing” T2 diabetes if you survive the operation
Average initial weight of participants was 104 kg (229 lb). Bypass patients dropped their weight by 25 kg (55 lb)and HgbA1c decreased by 1.8% (absolute decrease), compared to intensive medical management participants who lost 10.3 kg (32 lb) and dropped HgbA1c only by 0.4%.
I doubt that intensive medical therapy included a low-carb Mediterranean or paleo diet.
Diabetic Mediterranean Diet 
Aren’t patients of this surgery still dropping like flies 10-15 years after the procedure? Then there is the massive depression associated with this butchery. With in one week, I was able to drop my morning glucose levels by 36 points by eating the paleo way. It’s not easy but neither is living with diabetes. Thank you for joining in on letting people know there are alternatives that work.
Hi, MB. I hadn’t heard about a high late mortality rate. Within 30 days of surgery, the mortality rate is 0.1%, which is one in a thousand if my math is right. There are some additional deaths after that. The need for re-operations is also significant (to correct internal hernias, for example).
