Dr. Karan Rajan is an NHS surgeon and one of the biggest health and science creators on social media. Since 2020 he has amassed more than seven million followers across his channels with his refreshingly frank medical myth-busting and health-advice videos which combine education, entertainment, and generous servings of dark humor. In addition to being a regular advocate of health promotion on behalf of the NHS and the UK government, he has also worked closely with the UN, the World Health Organization, and the British Red Cross in an ambassadorial capacity. He is a senior clinical lecturer at the University of Sunderland School of Medicine and was formerly at Imperial College London.

His book This Book May Save Your Life: Everyday Health Hacks to Worry Less and Live Better is out now online and in stores and you can follow Dr Karan @drkaranrajan
