Laparoscopic gastric bypass resulted in significant and sustained weight loss with successful treatment of T2DM up to 87.1%. Despite a slightly lower response rate of T2DM treatment, patients with BMI <35 still had an acceptable DM resolution, and this treatment option can be offered to this group of patients.

LMGB has a low complication and mortality rate. The learning curve is less steep than for LRYGBP, whereas the efficacy is similar.

The prevalence of SHPT is high in morbidly obese patients before bariatric surgery which is related to vitamin D deficiency. The prevalence of SHPT increased continually along with the time after bariatric surgery, especially in patients receiving SAGB, followed by RYGB. The supplementation of vitamin D and calcium have to be higher in bypass procedure, especially in malabsorptive procedure.

Morbidly obese patients receiving gastric bypass surgery may need to tailor the bypass limb according to BMI. The application of gastric bypass in lower BMI patients should be more carefully.
