Over 120,000 Americans were reported to have had obesity surgery in 2003. After surgery, many obese patients not only lose significant amounts of weight, they also notice and improvement or total cure of other conditions such as diabetes, high blood pressure and high cholesterol. A study to assess the long term effects of obesity surgery found that after two years, patients lost over 23% of weight. After 10 years, there was only a 16% weight loss which was also associated with improvement in diabetes and other conditions related to obesity. However, after 10 years, high cholesterol and high blood pressure, there was no improvement compared to the control group. Some researchers claim that this lack of improvement is age related rather than weight loss related. Longer term studies are needed to ultimately determine if obesity surgery effectively prevents heart attacks and strokes and whether life expectancy is improved.
