Although
diet,
exercise,
behavior therapy and
anti-obesity drugs are first-line treatment, medical therapy for severe obesity has limited short-term success and very poor long-term success.
Weight loss surgery generally results in greater weight loss than conventional treatment, and leads to improvements in
quality of life and obesity related diseases such as
hypertension and
diabetes mellitus. A meta-analysis of 174772 participants published in
The Lancet in 2021 found that bariatric surgery was associated with 59% and 30% reduction in all-cause mortality among obese adults with or without
type 2 diabetes respectively. This meta-analysis also found that median life-expectancy was 9.3 years longer for obese adults with diabetes who received bariatric surgery as compared to routine (non-surgical) care, whereas the life expectancy gain was 5.1 years longer for obese adults without diabetes.
Bariatric treatments in youth must be considered with great caution and with other conditions that may not have to be considered in adults. Techniques used in bariatrics include
bioelectrical impedance analysis, a method to measure
body fat percentage. ==See also==
