In his new role, Dr Ramana will have independent charge of Asia for IBC, a medical body of surgeons specialising in obesity and diabetes surgery, a release from Belle Vue Clinic said.
Dr Ramana, associated with the hospital, will be responsible for helping with training, teaching, mentoring and communicating with the Asian bariatric surgical community.
He said obesity and diabetes are twin problems consuming healthcare in urban India and other Asian countries like China and Taiwan.
"The difference between the Asian diabetic population and the Western one is that Asians fall to diabetes at a lower body mass index (BMI). This means that even slightly obese would make one more vulnerable to getting diabetes," he said.
