A chronic disease is a long-lasting health condition that generally cannot be cured but can be managed with treatment, lifestyle changes, and regular medical follow-up. Korea has high rates of several chronic diseases including diabetes and hypertension.
The World Health Organization (WHO) defines a chronic disease (also called a non-communicable disease or NCD) as a condition that is of long duration, generally slow in progression, and is not passed from person to person. Chronic diseases are the leading cause of death and disability globally, accounting for 74% of all deaths worldwide. In Korea, the burden of chronic disease is significant — the country has high rates of type 2 diabetes, hypertension, obesity, cardiovascular disease, and chronic kidney disease, partly attributable to rapid urbanisation, sedentary lifestyles, and dietary changes.
Common chronic diseases include: cardiovascular diseases (coronary artery disease, heart failure, stroke), metabolic conditions (type 2 diabetes, obesity), respiratory diseases (asthma, COPD), musculoskeletal conditions (osteoarthritis, rheumatoid arthritis), neurological conditions (multiple sclerosis, epilepsy), mental health conditions (depression, anxiety disorders), and cancers. Unlike acute illnesses, chronic diseases require ongoing management rather than a single cure.
Managing a chronic condition well in Korea typically involves regular check-ups at community health centres for monitoring and medication management, adherence to prescribed medications, lifestyle modifications (diet, physical activity, smoking cessation), and monitoring for complications. Korea's community health centre network and major hospitals provide comprehensive chronic disease management programmes for registered patients. Early diagnosis and consistent management significantly improve outcomes and quality of life.
