Final answer:
Diabetes is a condition where the body cannot control blood glucose levels due to a lack of insulin production in Type 1 diabetes, or insulin resistance in Type 2 diabetes, leading to high blood sugar and potential health complications.
Step-by-step explanation:
Quentin was told his body no longer controls the amount of glucose in his blood, a condition known as diabetes. There are two main types of diabetes: Type 1 diabetes, where the pancreas fails to produce enough insulin due to the destruction of beta cells, and Type 2 diabetes, characterized by insulin resistance or the body's cells failing to respond to insulin.
In Type 1, without insulin, blood glucose levels rise dangerously because glucose is not taken up by the cells for energy, nor is excess glucose stored as glycogen in the liver. In Type 2, insulin may still be produced, but the cells do not respond effectively, leading to high blood sugar levels and potential malnutrition since the cells are unable to take in glucose.
