Bariatric surgery: 3 common questions

When overweight people consider bariatric surgery, one of their first questions is this: How much weight will I lose?


That depends on the person, says Dr. Daniel T. McKenna, a surgeon with Aurora BayCare Bariatric Surgery.


“The weight loss really depends on where they’re starting off. Some people are very short for their weight. They may be only 75 to 100 pounds overweight. Those patients probably will lose all of that weight,” McKenna says.


For most people, “the average is usually over 100 to close to 200 pounds,” he says.



Another frequent question: How long will it take to lose the weight?


“Men tend to lose weight faster than women. There are some men who may only lose weight six to nine months and then they’ll plateau. They’ll be already at their ideal body weight, though,” McKenna says.


“A lot of patients will lose weight for one to two years, but the average is around 18 months.”



Still another frequent question: What are the risks of bariatric surgery?


“Bariatric surgery has a level of complication that is around 3 to 5 percent. … The risk of death is higher when you have your hip or your knee replaced,” McKenna says.


“There are pathways in place to make sure that patients are prevented from having major complications such as blood clots, heart attacks, strokes.”
