Research the genetic and biomechanical markers of human adipose tissue on patients with morbid obesity. Additional tissue/fluid collection is also gathered during the time of surgery.
Study participation by invitation after complete pre-surgical work up at UC Davis Health System. Patients will be invited to participate if they meet all inclusion criteria's after completing all necessary clinical visits including lab studies, counseling, and participation in educational programs. During the pre-operative visit patients interested in participation will complete all necessary consent documentation. Pre-operative labs (blood and urine) will be collected along with additional blood, urine, and fecal samples will be collected pre-operatively. During surgery (Roux-en-Y Gastric Bypass surgeries only) tissue collection will include subcutaneous \& omental fat, jejunum, and liver biopsy. Post surgery patient will be observed for weight loss and resolution of co-morbidities. At designated times post surgery when lab studies are ordered additional blood/urine samples will be collected and analyzed.
Study Type
OBSERVATIONAL
Enrollment
500
Patients wishing to participate in the research will complete all necessary pre-operative work-up labs, testing \& counseling, complete and sign the informed consent. During weight loss surgery a small amount of subcutaneous and omental fat will be collected for analysis, with subsequent blood collection post surgery for analysis.

RECRUITINGTensile Strength of White Adipose Tissue
During the research tissue samples were compared between healthy obese patients (no diabetes, controlled HTN, no dyslipidemia) with tissue samples collected on non-healthy obese patients (type II diabetes) and using fat collected from mice as a control.
