Within the healthcare field, the term “chronic” describes conditions that last one year or more and require ongoing medical attention, limit daily living activities, or both.
Some examples of chronic diseases include:
- heart disease
- lung disease
- kidney disease
- Alzheimer’s disease
Chronic diseases are considered to have multiple factors contributing to their onset. Additionally, they often have a long development period during which the patient experiences no symptoms, and they worsen as the disease progresses.
