What is diabetes mellitus primarily related to?

Excessive production of insulin
Improper use of glucose
High levels of physical activity
Decreased physical endurance

The correct answer is: Improper use of glucose

Diabetes mellitus is primarily related to improper use of glucose in the body. This condition involves issues with insulin, either in its production (as in type 1 diabetes) or in the way the body responds to it (as in type 2 diabetes). In a healthy metabolism, insulin facilitates the uptake of glucose into cells, where it can be used for energy. However, in diabetes, the body’s ability to utilize glucose is impaired, leading to elevated levels of glucose in the blood, which can cause a range of health complications over time. Improper use of glucose signifies that the body either cannot produce sufficient insulin to facilitate this process or the cells are resistant to the effects of insulin. This altered glucose metabolism is at the core of diabetes and is essential for understanding how the condition affects overall health and management strategies, including dietary choices and exercise recommendations tailored for individuals with diabetes.
