Laparoscopic Sleeve Gastrectomy (LSG) is the latest method of bariatric surgery used to treat clinically severe obesity. Percentage of excess weight loss (EWL) is commonly used as a marker of success or failure of LSG affecting the quality of life (QoL) of obese.


To find out the relationship between EWL and the QoL of patients after LSG.

Materials and Method

A descriptive cross sectional study of 100 patients who have completed at least six months after LSG were selected using convenience sampling technique. 50% of the sample was obtained from the GI Surgery OPD in a tertiary care hospital, Kerala and 50% through telephonic interview. Data on QoL was collected using SF-36 questionnaire


The mean weight of the subjects before surgery was 115.99Kg +/-22.97, while the mean weight after surgery was 84.02Kg +/-17.75. The mean percentage of EWL was 63.31Kg+/-26.20. The mean bMI before surgery 42.46 Kg/m2 +/-6.02 came down to 30.76 Kg/m2 +/-5.04 after surgery. A positive correlation was found between QoL and EWL (p =0.768)


There is agreement that weight loss leads to better QoL. However, the need for longitudinal studies with multiple check points on the determinants of QoL including weight loss cannot be neglected
