Women under the age of 50 lose an average of one-forth of their body weight after adjustable gastric banding weight loss surgery, while men over the age of 50 lose nearly one-fifth of their body weight according to new study from Switzerland. Younger women lost more than one-forth of body weight, roughly 70 pounds
Younger women, that is those under the age of 50, lost an average of 28.2 percent of their body weight.
This would be an average weight loss of 70 pounds for a woman with a starting weight of 250 pounds.
Older men lost one-fifth of body weight, roughly 58 pounds
Older men, that is those over 50, lost an average of 19.4 percent of body weight.
This would be an average weight loss of 58 pounds for a man with a starting weight of 300 pounds.
Older women and younger men lost less weight
Older women and younger men lost less than this, however, however, I do not know exactly how much because I have not been able to get a copy of the paper.
Super obese lost nearly one-third, less obese lost one-fifth
Super obese with a BMI greater than 50 lost an average of 30.5 percent of their body weight whereas those with a BMI of less than 35 lost an average of 22.8 percent.
Example: Woman at 290 lbs with BMI of 50 would have lost roughly 89 lbs
This means that a super obese women with a BMI of 50, weighing 290 pounds at a height of 5-feet-4-inches tall, would lose an average of 89 pounds.
Example: Woman at 204 lbs with BMI of 35 would have lost roughly 47 lbs
An obese women of the same height but with a BMI of 35 would mean that she would weigh 204 pounds, would lose an average of 47 pounds.
Less than one-forth had complications
Less than one-forth of patients (22.3 percent) had complications.
Men had more band leaks than women: 7% vs 2%
Men had more band leaks than women (7 percent versus 1.9 percent).
Heaviest patients least likely to have complications
Only one-in-nine patients (10.6 percent) with a BMI greater than 50 had complications compared to 18.8 percent of those with a BMI of 35-40, and 23 percent of those with a BMI of 40-50.
“Adjustable gastric banding is an effective intermediate-term treatment for severe obesity,” the authors concluded. “Preoperative age, sex, and BMI are important modulators of outcome and should be considered during preoperative evaluation.”
Subjects: 404 severely obese patients, 79% women
The study involved 404 severely obese patients of whom 79 percent were women.
42-years-old, BMI 42
On average they were 42-years-old, had a body mass index (BMI) of 42, and had been followed for 4-years after surgery.
