When does diabetes become life-threatening?

Diabetes can become life-threatening primarily when it is untreated. In the absence of appropriate treatment, blood glucose levels can rise to dangerous levels, leading to acute complications such as diabetic ketoacidosis or hyperglycemic hyperosmolar state. Both of these conditions can result in severe metabolic disturbances, dehydration, and potentially lead to coma or death if not managed promptly.

While insulin resistance and elevated blood pressure can exacerbate the complications of diabetes, they do not directly cause the acute life-threatening conditions that are characteristic of untreated diabetes. Adherence to treatment is crucial in managing diabetes effectively and preventing these serious outcomes. Thus, the correct choice highlights the critical importance of recognizing and addressing diabetes without delay to ensure patient safety and health.
