Constance's body is capable of producing insulin, but the insulin is misused. her condition is known as pre-diabetes.

Explanation:

Prediabetes is the preliminary stage of diabetes mellitus where all the symptoms necessary for the diagnosis of diabetes are absent, but the blood sugar is abnormally high.

Prediabetes is associated with obesity (especially abdominal or visceral obesity), high triglyceride and / or low HDL cholesterol dyslipidemia and hypertension. Therefore, it is a metabolic diathesis or syndrome, and it usually does not produce any symptoms, and the only symptom is high blood sugar.  

Impaired fasting blood glucose and impaired glucose tolerance are two types of prediabetes that are similar in clinical description (high blood glucose levels in both cases) but are physiologically different. Insulin resistance, insulin resistance syndrome and prediabetes are closely related and have overlapping aspects.
