What condition is associated with insulin resistance and insufficient insulin production?

Type 2 diabetes mellitus is characterized by both insulin resistance and inadequate insulin production. In this condition, the body's cells become less responsive to insulin, which is a hormone that facilitates glucose uptake from the bloodstream into the cells. Over time, as the body requires more insulin to manage blood glucose levels effectively, the pancreas may not be able to produce sufficient amounts of insulin to overcome this resistance. This combination leads to elevated blood sugar levels, a hallmark of type 2 diabetes.

Type 1 diabetes mellitus primarily involves the destruction of insulin-producing beta cells in the pancreas, leading to absolute insulin deficiency without the significant insulin resistance seen in type 2 diabetes. Gestational diabetes occurs during pregnancy and is characterized by insulin resistance, but it does not typically involve the chronic aspects associated with type 2 diabetes after pregnancy. Diabetes insipidus is unrelated to insulin or blood glucose levels; it is a condition characterized by an inability to concentrate urine due to a deficiency of vasopressin, a hormone unrelated to glucose metabolism.
