Wow, thank you so, so much for replies! They were super helpful and I have actually made up my mind finally, woo hoo! I have decided to go with the bypass due to my bmi and due to issues with my metabolism being slow from my hypothyroidism, but mostly because I feel I can definitely meet my goal weight and stay at that weight successfully with this surgery. I am new on here, so I really appreciate the thoughts and insights!
I'm really sorry this happened to you, but this kind of thing is extremely rare. People can have bad complications from the sleeve, too, but as with bypass, they are very rare. I've been involved in the bariatric community for several years and you almost never hear about this kind of thing. The vast majority of people who've had either kind of surgery have had either no complications at all or very minor ones that were an easy fix.
P.S. You only joined this forum two hours ago? If you'd have been on here for several years, you'd know what you described almost never happens. I've been on this and another popular bariatric forum for about six years, and volunteer with bariatric patients at my clinic, and I can count the number of severe cases like this one on hand....
