Obese Teens Who Receive Gastric Banding Achieve Significant Weight Loss

Chicago — A higher percentage of severely obese adolescents who received laparoscopic adjustable gastric banding lost more than 50 percent of excess weight and experienced greater benefits to health and quality of life compared to those in an intensive lifestyle management program, according to a study in the February 10 issue of JAMA.

Adolescent obesity is a serious health challenge globally. In the U.S., more than 17.4 percent, or more than 5 million adolescents were obese in 2004, an increase from 14.8 percent in 2000. Obesity is associated with both immediate and late health effects and reduced life expectancy, according to background information in the article. Lifestyle programs that have included changes in diet, exercise, and behavior to promote weight loss often have poor results. “Bariatric surgery is now extensively used for adults and is being evaluated for adolescents,” the authors write. “Laparoscopic adjustable gastric banding (gastric banding) has the potential to provide a safe and effective treatment.”

Model Estimates Risks and Benefits of Bariatric Surgery for Severely Obese

Chicago — A computerized model suggests that most morbidly obese individuals would likely live longer if they had gastric bypass surgery, according to a report in the January issue of Archives of Surgery, one of the JAMA/Archives journals. However, the best decision for individual patients varies based on factors such as age, increasing body mass index and the effectiveness of surgery.

An estimated 5.1 percent of the U.S. population is morbidly obese, often defined as having a body mass index (BMI) of 40 or higher, according to background information in the article. Available evidence suggests that dietary, behavioral and pharmacologic treatments frequently do not result in meaningful weight loss for individuals in this group. Bariatric surgery appears to be the only effective therapy for promoting clinically significant weight loss and improving obesity-related health conditions for the morbidly obese. However, the procedure is not without risk, including in-hospital death.

Daniel P. Schauer, M.D., M.Sc., of the University of Cincinnati Academic Health Center, and colleagues used two nationally representative surveys and a recent large observational trial to construct a model estimating the benefits and risks of gastric bypass surgery for individuals with morbid obesity. The model included data from almost 400,000 individuals nationwide to estimate the risk of death from obesity and its complications; data from 23,281 patients undergoing bariatric surgery to calculate in-hospital death rates following the procedures; and outcomes from participants in a seven-year study to determine the effects of surgery on survival and to calibrate and validate the model.

Linking weight loss to less sleep apnea

Temple-led study, the largest of its kind, finds weight loss has significant impact on the disorder

More than 12 million people in the U.S. suffer from sleep apnea, most common among the overweight and obese. More than just loud snoring, it can lead to high blood pressure, stroke, cardiovascular disease and a poor quality of life. For years, doctors have told patients with sleep apnea that their best bet for alleviating it would be to lose weight, but there’s been very little research-based evidence to prove that.

“Existing research has been limited by a number of factors, so there are very few studies that show whether the recommended amount of weight loss – about 10 percent – is enough to sufficiently improve sleep apnea,” said Gary Foster, director of the Center for Obesity Research and Education.

Foster and colleagues from six other universities recently completed the largest randomized study on the effects of weight loss on sleep apnea in patients with type 2 diabetes. They found that among patients with severe sleep apnea, those who lost the recommended weight were three times more likely to nearly eliminate the number of sleep apnea episodes compared to those who did not lose weight. The results are published in the Sept. 28 issue of the Archives of Internal Medicine.

The new study, called Sleep AHEAD, looked at 264 obese patients with type 2 diabetes already enrolled in the Look AHEAD trial, an ongoing 16-site study investigating the long-term health impact of an intensive lifestyle intervention in 5,145 overweight or obese adults with type 2 diabetes. Participants were between 45 and 75 years old.

The 264 participants were broken into two randomized groups: the first received a group behavioral weight loss program developed especially for obese patients with type 2 diabetes, portion-controlled diets, and a prescribed exercise regimen of 175 minutes per week. The second attended three group informational sessions over a one-year period that focused on diabetes management through diet, physical activity and social support.

After one year, members of the first group lost an average of 24 pounds. More than three times as many participants in this group had complete remission of their sleep apnea (13.6 percent compared to 3.5 percent), and also had about half the instances of severe sleep apnea as the second group. Further, participants in the second group only lost about a pound, and saw significant worsening of their sleep apnea, which suggested to Foster and his team that without treatment, the disorder can progress rapidly.

“These results show that doctors as well as patients can expect a significant improvement in their sleep apnea with weight loss,” said Foster, the study’s lead author. “And a reduction in sleep apnea has a number of benefits for overall health and well-being.”

Weight loss Before and After Photos: Gastric Bypass

In general defined, gastric bypass surgery describes any bariatric procedure that alters the digestive tract so that certain parts are “bypassed”. The food when passes through this altered tract, the body absorbs from it less calories than usual. The gastric bypass is the operation more commonly used to neutralize obesity.

Here are some photos before and after a gastric bypass surgery. For more information feel free to contact Doctor Norman Jalil.
