Serum beta-endorphin levels in morbidly obese patients: the effect of vertical banded gastroplasty.
The associations between serum beta-endorphin levels and clinical and metabolic variables as well as beta-endorphin changes after surgically induced weight loss were investigated in 43 morbidly obese patients. A significant positive correlation between beta-endorphin and body weight, degree of body weight increase and ACTH was found preoperatively. Only body weight was independently associated with beta-endorphin levels. Twelve months following vertical banded gastroplasty, there was an extensive weight loss in all patients and improvement in their metabolic profile. A significant reduction in beta-endorphin levels which was proportional to the extent of weight loss was also observed.

The effect of vertical banded gastroplasty on glucose-induced beta-endorphin response.
beta-Endorphin is an endogenous opioid involved in the regulation of food intake and obesity as well as in insulin metabolism. In this study, we investigated glucose-induced beta-endorphin, insulin, and glucose responsiveness in morbidly obese patients and the effect of surgically induced weight loss.. Thirty-two healthy, nondiabetic, morbidly obese patients (body mass index over 40 kg/m2) and 32 normal-weight controls were studied. Serum levels of beta-endorphin, insulin, and glucose were measured under basal conditions and during an oral glucose tolerance test (OGTT) before and 12 months following vertical banded gastroplasty.. Preoperative basal levels of beta-endorphin, insulin, and glucose and their responses during OGTT in obese patients were significantly higher compared with those of controls. After surgery, basal beta-endorphin, insulin, and glucose levels decreased significantly compared with preoperative values. Postoperative basal insulin and glucose levels were similar to those in controls, while beta-endorphin levels remained significantly higher than those of controls. A significant reduction in total responses of beta-endorphin, insulin, and glucose during OGTT was also observed; however, postoperative beta-endorphin and insulin responses remained significantly higher than in controls.. Morbidly obese patients have an increased glucose-stimulated response of beta-endorphin, insulin, and glucose which is partially corrected with weight loss following vertical banded gastroplasty.
