Hello. I've read a lot of promising stories about weight loss surgery results. I also heard later about not so pleasant side effects of this surgery, anemia, infection and even death. I know that gastric bypass surgery can be good solution for people who can't lose weight quickly, but they have to, otherwise they are in serious danger of damaging their health. Now, reading about this side effects, they risk their health even if they undergo the surgery. What is your opinion on weight loss surgery? Is it effective and more important question, is it safe?
