What term describes a condition where there is an insufficient insulin response, leading to high blood sugar levels?

The condition characterized by an insufficient insulin response leading to high blood sugar levels is known as Type 2 diabetes. In Type 2 diabetes, the body either becomes resistant to insulin or does not produce enough insulin to maintain normal glucose levels. This lack of effective insulin response results in elevated blood sugar levels, which can lead to a range of health complications if not managed properly.

Type 1 diabetes is an autoimmune condition where the pancreas produces little to no insulin. Gestational diabetes occurs during pregnancy and typically resolves after giving birth, though it increases the risk for developing Type 2 diabetes later in life. Hypoglycemia refers to low blood sugar levels, which is not applicable in this case, as the question focuses on high blood sugar levels. Thus, Type 2 diabetes is the most accurate descriptor for the condition in question.
