Lifestyle medicine uses evidence-based changes to daily habits — what you eat, how you move, sleep, manage stress and connect with others — to help prevent and manage chronic diseases such as type 2 diabetes, high blood pressure and heart disease. It is organised around 8 pillars, drawing on guidelines from the American College of Lifestyle Medicine (ACLM) and the European Lifestyle Medicine Organization (ELMO).
What is lifestyle medicine?
The American College of Lifestyle Medicine defines lifestyle medicine as the use of evidence-based therapeutic lifestyle interventions as a primary modality to prevent, treat, and often reverse chronic disease. These interventions include dietary change, physical activity, restorative sleep, stress management, avoidance of risky substances and positive social connection.
At STAT Medical @ Hougang, we integrate these 8 pillars into personalised care plans for chronic conditions like diabetes, hypertension, heart disease and obesity. The focus is on sustainable changes rather than quick fixes, alongside — not instead of — conventional medical care.
