The mean body mass index among study participants was 39.18 + 11.77 kg/m² while the median BMI was 40.74 kg/m². This indicates that most of study participants are morbidly obese. The most frequent type of bariatric surgery was gastrectomy operation (n= 101, 77.1%). There were a number of participants who reported having gallstone after the surgery (n= 24, 18.3%). The timing of gallstone formation varied among study participants
