"The surgery was performed about a month back after which the patient's weight decreased by seven kgs," said Dr Mohit Bhandari, Bariatric Surgeon at Sri Aurobindo Institute of Medical Sciences (SAIMS).
Bhandari claimed that the boy was the youngest patient in the country to undergo this kind of surgery on June 19.
The boy weighed 60 kgs and his BMI (Body Mass Index) was about 50 before the surgery. He used to face breathing problems, sleep apnea and hormonal disorders due to it, the doctor said.
According to Bhandari, the boy is expected to lose another 25-30 kgs of weight in the next six months.
Twenty percent children in the country fall in 'obese' category and by 2015 this figure will cross 30 per cent, he said.
