About the Author

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.
