What type of medical training do endocrinologists receive?

After five and a half years of MBBS and three years of MD/ DNB training, which can be done either in internal medicine or paediatrics, DM/ DNB in endocrinology and metabolism will take three more years. In addition to this, the postgraduate medical qualifications in Endocrinology, awarded in the United States of America, United Kingdom, Canada, Australia & New Zealand are recognised by Medical Council of India as equivalent degrees.
