This prospective, observational, non-interventional study aims to evaluate the effect of gestational weight gain on regional anesthesia characteristics in pregnant women undergoing elective cesarean delivery. No additional intervention, medication, or procedure beyond routine clinical care will be performed. Participants will be classified according to gestational weight gain categories based on the Institute of Medicine (IOM) 2009 guidelines, and spinal anesthesia block characteristics, hemodynamic responses, and perioperative outcomes will be assessed.
