Brief Summary:
The primary objective is to compare inflammatory, hormonal, and metabolic changes in the very short term after various bariatric surgical procedures (Roux-en Y Gastric Bypass, Vertical Sleeve Gastrectomy, and Adjustable Gastric Banding)and other abdominal surgeries, as well as to compare these changes to diet-induced changes in the same population.

Group/Cohort Intervention/treatment
Weight loss surgery
This group will be comprised of people having weight loss surgery: Roux-en Y gastric bypass, vertical sleeve gastrectomy, or adjustable gastric banding
Procedure: Weight loss surgery
Weight loss surgery

Abdominal surgery
This group will be comprised of people having abdominal surgeries such as nissen fundoplication or cholecystectomy.
Procedure: Laparoscopic abdominal surgeries
laparoscopic abdominal surgeries

This group will be comprised of normal weight healthy volunteers.

Primary Outcome Measures :
  1. Determine to what extent improvements in glycemic control can be attributed to caloric restriction after weight loss surgery [ Time Frame: 10 days post-op ]

Secondary Outcome Measures :
  1. Determine changes in inflammatory markers after weight loss surgery [ Time Frame: 10 days post-op ]

Biospecimen Retention:   Samples With DNA
plasma and serum
