How risky is it to reverse a gastric bypass surgery?

I had a gastric bypass surgery around 15 years ago. I only lost 44kg, which is not considered good enough. I have been regaining weight, with this year being the worst, despite the fact that I barely eat (attributed to a metabolism shut-down). I also have serious malnutrition and bone density issues. How risky is undergoing a procedure to reverse the surgery? What kind of consequences am I looking at? How can I decide whether to do the reversal? If I do, how do I minimise risk? Thank you!
