Ghrelin and Apolipoprotein AIV Levels Show Opposite Trends to Leptin Levels During Weight Loss in Morbidly Obese Patients

Background Although bariatric surgery is the most common procedure used to induce weight loss in morbidly obese patients, its effect on plasma satiety factors (leptin, ghrelin, and apolipoprotein (apo)-AIV) is controversial. The aim of this work was to analyze these parameters before and at different times after surgery.
