| Also, weight loss surgery forces people to change their eating habits radically, makes them violently ill if they overeat and because gastric bypass operations cause food to skip the duodenum, where most iron and calcium are absorbed, it puts them at lifelong risk for major nutritional deficiencies. |
Many patients lose more than 100 - 200 pounds. Some reach a normal weight, while others remain heavy, though less overweight than before.
With drugs or diet, most patients can realistically hope to lose no more than 10 percent of their body weight - a mere 30 pounds in someone who weighs 300, for instance - and even that may not last.
By comparison, one study shows that 10 years after the most commonly performed bariatric operation, the gastric bypass, patients on average have maintained a loss of 60 percent of their excess weight.
