Who Loses Weight After Gastric Bypass Surgery
It is known that gastric bypass surgery does not give equally successful weight loss results to all patients. A new research suggests that diabetics and those with a larger stomach pouches lose less weight than the others do.
Gastric bypass surgery is a procedure when stomach size is being changed to limit the possible amount of food intake. This is being done by creating a stomach pouch which is smaller than the stomach and it helps lose weight quickly, effectively, and safely. However, from 5% to 15% of patients do not significantly benefit from the surgery, and this study reveals who exactly doesn't benefit from this weight loss surgery.
The study comes from a team of researchers from University of California, San Francisco and examines 361 patients who underwent a weight loss surgery during the period between 2003 and 2006. Participants were followed for a year and 310 patients finished the study. It was defined that 40% excess weight loss is not a good result, but over 40% is a good one.
At the beginning of the study the average body mass index (BMI) was 52, after the study it was 34. Most patients lost weight significantly, but there were 38 patients (12.3%) who reported poor weight loss. Researchers found that diabetics and those with larger stomach pouch after a surgery lost less weight than others did.
Researchers suggest that diabetes drugs may stimulate fat and cholesterol increase while trying to control blood sugar levels. For those with a larger stomach pouch the study suggests sizing balloon used to define the new size of stomach should be replaced by an algorithm, which should take into account patient's anatomical landmarks to estimate the optimal size.
Overall, researchers urge the need of improving gastric bypass surgery results because it is a very effective weight loss treatment, which becomes more and more popular. This study suggests changes in diabetes drugs to improve the weight loss surgery outcomes and help patients fight excess weigh and changes in terms of defining stomach pouch size before the surgery.
