The Effect of Surgically Induced Weight Loss on Endocrine Function, Cardiovascular Function and Body Composition
This trial is active, not recruiting.
|Sponsor||Johns Hopkins University|
|Start date||May 2007|
|End date||October 2010|
|Trial size||70 participants|
|Trial identifier||NCT00686972, NA_00004876|
This study is being conducted to evaluate changes in sugar, metabolism, heart function and changes in body composition as patients lose weight following bariatric surgery. The investigators will compare improvements of the above changes as a function of the four different types of bariatric surgery. The investigators believe the most beneficial and safest procedure will be the Roux-en-Y.
|Endpoint classification||safety/efficacy study|
|Intervention model||single group assignment|
time frame: 2 years
Male or female participants from 21 years up to 65 years old.
Inclusion Criteria: - Male and female volunteers 21-65 years. - BMI > 40. - Preoperative hematocrit level of at least 34% for women and 38% for men. - Postoperative hematocrit level of at least 34% for women and 36% for men.

|Description||The study will also examine the response of the pancreas (the insulin-producing organ) to a sugar load, as well as to a hormone called GLP-1, which is released from your gut to maximally stimulate your pancreas. The release of this hormone increases when you eat food and it causes the pancreas to release more insulin than does sugar alone. Volunteers will have 22 visits over a two year period. Only people having Roux-en-Y gastric bypass surgery, gastric sleeve surgery, duodenal switch gastric surgery or lap-band/gastric banding surgery may join. Seventy volunteers will be recruited to take part in this study.|
