The goal of this observational study is to assess the preoperative gastric residual volume in adult patients undergoing elective surgery. The main question it aims to answer is:
Does gastric residual volume, content type, and aspiration risk differ between diabetic and non-diabetic patients with similar fasting durations?
Participants undergoing elective surgery will receive bedside gastric ultrasound as part of their preoperative assessment. Ultrasound images will be used to estimate gastric volume and evaluate aspiration risk.

Primary outcome measure(s)
Residual gastric volume (mL) measured by bedside ultrasound in diabetic vs. non-diabetic patients. — Immediately before induction of anesthesia (preoperative period) The main question of the study is whether gastric emptying is delayed in diabetic patients, resulting in a higher residual gastric volume.
