Ghrelin Levels After Gastric Bypass Surgery
Review of Serum Ghrelin Levels in Response to Glucose Load in Obese Patients After Stomach Bypass
Serum ghrelin levels in response to glucose load in obese subjects post-gastric bypass surgery
We sought to elucidate further the mechanisms leading to weight loss after gastric bypass (GBP) surgery in morbidly obese individuals. Ghrelin is a gastroenteric appetite-stimulating peptide hormone, fasting levels of which decrease with increasing adiposity and increase with diet-induced weight loss. In addition, ghrelin levels rapidly decline postprandially.
We measured serum ghrelin responses to a 75-g oral glucose tolerance test (OGTT) in 6 subjects who had undergone gastric bypass surgery 1.5 +/- 0.7 years before testing and compared these responses with 6 obese subjects about to undergo gastric bypass surgery, 6 obese nonsurgical subjects (matched for BMI to the post-GBP surgical group), and 5 lean subjects.
Despite weight loss induced by the gastric bypass surgery, fasting serum ghrelin levels were significantly lower in the post-gastric bypass surgery group than in the lean subject (by 57%) or pre-gastric bypass surgery (by 45%) group. Serum ghrelin levels during the OGTT were significantly lower in postoperative than in lean, obese pre-gastric bypass surgical, or obese nonsurgical subjects. The magnitude of the decline in serum ghrelin levels between 0 and 120 minutes post-OGTT was significantly smaller in postoperative (by 62%), obese pre-gastric bypass surgical (by 80%), or obese nonsurgical (by 69%) subjects in comparison with lean subjects.
Serum ghrelin levels in response to OGTT are lower in subjects post-gastric bypass surgery than in either lean or obese subjects. Tonically low serum ghrelin levels may be involved in the mechanisms inducing sustained weight loss after gastric bypass surgery.

Laparoscopic or open bariatric surgery, such as gastric banding or bypass is not an easy solution to morbid obesity and weight loss. It is a serious surgical procedure, involving health risks. To produce lasting weight loss it requires a long-term patient commitment to eating a healthy diet and following a regular program of physical exercise. Life-long use of nutritional supplements may also be necessary. So, before deciding, discuss your options fully with your doctor. © 2003-2018 Bariatric-Surgery.Info - Terms - Contact - Information - Resources
