Patients will be randomized in one of the two groups i.e. Group CG where patients will chew a sugar free gum for one hour and Group NG where no gum will be chewed. All patients will be assessed for Baseline residual gastric volume using point-of-care gastric ultrasound (POCUS-G) (V0), Quality of Recovery-15 (QoR-15), Anxiety using Amsterdam peri-operative anxiety scale (APAIS) at the beginning of the study in the preoperative room as baseline. Thirst score and Hunger score will be recorded as baseline. Thereafter, they will be asked to chew a sugar-free gum for an hour. After one hour, the gum will be removed and residual gastric volume will be assessed at the end of 1^st hr and then at the end of 2^nd hr. After the second residual gastric volume assessment, anxiety assessment using APAIS will be done along with Thirst score and Hunger score before the patient is wheeled in the OT. In the postoperative period, PONV score at 1^st, 4^th, 6^th, 12^th and 24^th hour, QoR-15 score at the end of day1 will be assessed.

The primary outcome will be residual gastric volume at the end of 1^st hour. The secondary outcomes will be residual gastric volume at the end of 2^nd hour,  APAIS Baseline and at 2^nd hour of gum chewing, PONV score at the end of 1^st, 4^th, 6^th and 12^th and 24^th hour post-operatively, Thirst score and Hunger score at baseline and at the end of 2^nd hour,  QoR – 15 score at baseline and at day one  Sore throat and Hoarseness at day one.
