Chronic illness is slow disease progression over time, may be long-lasting or greater than 6 months Unlike acute conditions, chronic health conditions cannot be cured—only controlled. Controlling (or managing) the symptoms of a chronic condition can often be done by creating a health care plan in partnership with your provider—the plan may include taking medication, healthy eating, physical or occupational therapy, exercise, or complementary treatments such as nutritional supplements. Frequently, chronic conditions can be prevented by practicing healthy lifestyle behaviors, such as staying physically active; maintaining a healthy weight and nutritional status; limiting sun exposure; and refraining from drugs, smoking, and excessive alcohol use.
