Which of the following chronic conditions affects the ability to control blood sugar levels?

Diabetes is a chronic condition characterized by the body’s inability to properly regulate blood sugar levels. This is primarily due to either insufficient insulin production (as seen in Type 1 diabetes) or insulin resistance (as commonly observed in Type 2 diabetes). Insulin is a hormone that facilitates the uptake of glucose from the bloodstream into cells for energy, and without effective insulin action, blood glucose levels remain elevated, leading to a variety of health complications over time.

Individuals with diabetes often need to monitor their blood sugar levels regularly to manage their condition effectively. They may use different treatment strategies, including lifestyle changes, oral medications, or insulin therapy, to keep their blood sugar within a target range. The direct impact of diabetes on blood sugar regulation is why it stands out as the correct response in this context, distinguishing it from the other chronic conditions listed.
