| Summary: | Nutrition education is important for patients with hypertension to reduce the adverse outcomes of the disease. A web-based approach has the potential for improving the quality of nutrition education. This paper describes a conceptual framework for the development of a web-based nutrition education system for patients with hypertension, also known as the Web-based Approach on the dietary management and physical activity to control hypertension (W.A.t.C.H) in Malaysia. The website aims to improve the nutrition knowledge and promote behavioural changes among patients. The Theory of Planned Behaviours, Self-Determination theory and Cognitive Load Theory will be used in the development of the website. The website will (1) serve as a portable resource for patients on nutritional education for blood pressure control; (2) supplement the hypertension clinical care by providing an online educational tool for patient. This paper illustrates how learning and multimedia theories can be used in the development of the website. © 2020 Published under licence by IOP Publishing Ltd.
