Which of the following is an example of a chronic disease?

Diabetes is an example of a chronic disease because it is a long-term condition that affects the body's ability to regulate blood glucose levels. Unlike acute illnesses, which typically resolve within a short period, chronic diseases like diabetes require ongoing management and care. Individuals diagnosed with diabetes often need to monitor their blood sugar levels regularly, adhere to specific dietary guidelines, and may require medications to manage their condition effectively over their lifetime.

In contrast, the flu is an acute viral infection that usually resolves within a few days to two weeks. Appendicitis is an acute condition requiring immediate medical attention, as it involves inflammation of the appendix and often necessitates surgical intervention. A sprain, which involves the stretching or tearing of ligaments, is also an acute injury that generally heals with appropriate rest and treatment over a short period. Thus, diabetes stands out as the only option that aligns with the characteristics of chronic disease due to its persistent nature and the need for continual management.
