About Author

Dr Umang Gupta ,I’m a doctor currently pursuing my DNB in Anaesthesiology, with a keen interest in perioperative medicine, critical care, and the science behind safe patient care. I have always enjoyed learning, but even more so, I enjoy understanding concepts deeply and finding simple, logical ways to explain them. Teaching and simplifying difficult medical topics is something I genuinely love, especially when it helps someone move from memorising information to actually understanding it. Through my clinical training and teaching experiences, I hope to keep building my knowledge while making medical learning more approachable, structured, and practical for others. Outside medicine, I enjoy staying active, learning new things, and finding balance beyond work.
