Surgery results in greater improvement in weight loss outcomes and weight associated comorbidities compared with non-surgical interventions , regardless of the type of procedures used .
When compared with each other , certain procedures result ed in greater weight loss and improvements in comorbidities than others .
Outcomes were similar between RYGB and sleeve gastrectomy , and both of these procedures had better outcomes than adjustable gastric b and ing .
For people with very high BMI , biliopancreatic diversion with duodenal switch result ed in greater weight loss than RYGB .
Isolated sleeve gastrectomy led to better weight-loss outcomes than adjustable gastric b and ing after three years follow-up .
BACKGROUND Bariatric ( weight loss ) surgery for obesity is considered when other treatments have failed .
The effects of the available bariatric procedures compared with medical management and with each other are uncertain .

Fewer Nutrient Deficiencies After Laparoscopic Sleeve Gastrectomy (LSG) than After Laparoscopic Roux-Y-Gastric Bypass (LRYGB)—a Prospective Study
Background Deficiencies in micronutrients after bariatric operations are frequent , despite routine supplementation . Main outcome measures were pre- and postoperative frequency of nutrient deficiencies and success rate of their treatment . Methods Between 5/2004 and 12/2006 , 136 patients ( m : f = 0:4 ) with an average body mass index of 45 ( 35–58 ) kg/m2 and age of 53 ( 21–66 ) years were prospect ively analysed . Laparoscopic Roux-Y-gastric bypass ( LRYGB ) was performed in 86 patients and laparoscopic sleeve gastrectomy ( LSG ) was performed in 50 patients . The patients were examined before surgery as well as 3 , 6 , 12 , 24 , 30 , and 36 months postoperatively using a st and ard protocol including laboratory tests . The mean follow-up time was 24.4 ( 12–40 ) months ; the follow-up rate was 100 % . Results Prior to surgery , 57 % of the patients had at least one deficiency , 23 % of whom had vitamin D3 deficiency . Frequent postoperative deficiencies after LSG  were zinc , vitamin D3 , folic acid , iron , and vitamin B12 ; after LRYGB , vitamin B12 , vitamin D3 , zinc , and secondary hyperparathyroidism . No vitamin B1 or B6 deficiencies were found . Calcium levels were normal in all patients . Treatment of the deficiencies was mostly successful . Conclusion Preoperatively , 57 % of morbidly obese patients already had a deficiency . Postoperatively , significantly more vitamin B12 and vitamin D deficiencies and hyperparathyroidism were found in patients who had undergone LRYGB . After LSG , folate deficiency was more frequent ( but not significantly so ) . Calcium levels were normal in all patients ; therefore , parathyroid hormone and vitamin D3 levels are more sensitive markers for early detection of disorders of calcium metabolism . Iron deficiency anaemia is most efficiently treated by IV therapy
