Study population: Adult patients aged 18-65 years with morbid obesity (BMI ≥ 35 kg/m²) who are scheduled to undergo elective laparoscopic sleeve gastrectomy at a tertiary care center.

Brief summary: This prospective observational study aims to evaluate whether preoperative immune-nutritional markers-specifically the Prognostic Nutritional Index (PNI), HALP score, Neutrophil-to-Lymphocyte Ratio (NLR), and C-Reactive Protein (CRP)-can predict early postoperative clinical outcomes such as time to oral intake, mobilization, complications, and length of hospital stay in patients undergoing elective laparoscopic sleeve gastrectomy.

* Severe hepatic or renal dysfunction
* Presence of active infection
* History of immunosuppressive therapy or hematologic malignancy
* Need for intensive care unit (ICU) admission within the first 72 hours postoperatively
* Preoperative administration of albumin or blood products
