Actual (reported)The study looks at whether a specific protein in the blood, called apolipoprotein, can predict how much weight a person might lose after sleeve gastrectomy, a surgery for people with severe obesity. We want to find a specific level of this protein that shows which patients are most likely to lose weight successfully after surgery. By identifying this level, we hope to guide doctors in deciding who should have the surgery and who might do better with non-surgical weight loss methods.
