A Nurse’s Diary (Hediyakage Dinapotha) is a health-information website created by Darshani Upeksha Samarakoon, a professional nurse working in the intensive care unit at the National Institute of Infectious Diseases in Angoda, Sri Lanka. Drawing on her nursing experience and medical information, the site aims to explain health topics in accessible language and help readers make informed choices about their wellbeing.

Its content includes articles on conditions such as dengue, heart disease, diabetes, cancer, mental health, liver disease, and antibiotic resistance, as well as first aid, child safety, and patient care. Readers can also access practical tools, including a BMI calculator, a heart-attack risk assessment, a pregnancy date calculator, and a first-aid guide. The site offers category-based browsing and search, and invites visitors to contact the author with health-related questions, feedback, or advertising enquiries.

The author clarifies that she is a nurse, not a doctor: the information provides guidance, not diagnosis or prescriptions, and readers are encouraged to consult a qualified physician about medical concerns.
