Which classification describes gestational diabetes that is diet controlled?

Gestational diabetes that is diet-controlled is classified as A1DM. This classification is part of the Gestational Diabetes Mellitus (GDM) classification system, where A1DM specifically refers to cases of gestational diabetes that can be managed through dietary modifications alone.

In this scenario, the pregnant individual has elevated blood glucose levels that do not require insulin or oral hypoglycemic agents; rather, these levels can be maintained within normal range solely through dietary management. A1DM typically indicates a less severe form of gestational diabetes that is often associated with a favorable pregnancy outcome when appropriately managed.

A2DM, in contrast, refers to cases of gestational diabetes where medication, such as insulin or oral hypoglycemic agents, is necessary to control blood glucose levels. This distinction is crucial in managing care and interventions during pregnancy.

Type 1 and Type 2 diabetes are not classifications of gestational diabetes but rather chronic forms of diabetes that predate pregnancy. Type 1 diabetes is characterized by absolute insulin deficiency due to autoimmune destruction of insulin-producing beta cells, while Type 2 diabetes is marked by insulin resistance and relative insulin deficiency. Neither of these classifications applies to gestational diabetes specifically.
