Why someone would choose that particular therapy which has many complications?

This kind of weight loss is for people who have severe obesity. It’s all a matter of risk-benefits. The mal-absorption operations are much cruel. They are even more effective than gastric bypass and lap band in terms of weight loss. In fact, these patients tend to lose 80% of their excess weight or more. So in some very, very large patients, perhaps in the four- or five-hundred-pound category, these operations will enable them to get closer to their ideal body weight. But there’s a price to pay for that. So there may be a role for these operations for some patients, but probably for the majority who are seeking bariatric surgery the gastric bypass or lap band would be the best options.
