What condition occurs due to insufficient levels of insulin?

The condition that occurs due to insufficient levels of insulin is hyperglycemia. Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood glucose levels. When there is not enough insulin to facilitate the uptake of glucose by the body's cells, glucose remains in the bloodstream, leading to elevated blood sugar levels, which is referred to as hyperglycemia.

Hyperglycemia can occur in various contexts, most commonly in diabetes mellitus. In type 1 diabetes, the pancreas produces little to no insulin, while in type 2 diabetes, the body may not use insulin effectively or may not produce enough of it. Without adequate insulin, the process of glucose metabolism is disrupted, resulting in high blood sugar levels and associated symptoms such as increased thirst, frequent urination, and fatigue.

In contrast, hypoglycemia is a condition characterized by abnormally low blood sugar levels, which can occur due to excess insulin or other factors but is not a direct result of insufficient insulin. Hypertension refers to high blood pressure and does not relate directly to insulin levels. Hypothyroidism involves insufficient production of thyroid hormones and is unrelated to insulin's function in glucose metabolism. Thus, the rationale behind hyperglycemia being the correct answer lies in the direct correlation between
