Which classification of diabetes mellitus occurs during pregnancy and typically resolves after childbirth?

Correct choices

A. The pancreas plays a central role in blood glucose regulation by releasing glucose into the bloodstream through glycogenolysis and gluconeogenesis when blood glucose levels are low. It also stores glucose as glycogen and responds to insulin and glucagon signals.

Incorrect choices:

b. This choice is incorrect. While the kidneys play a role in filtering blood and excreting waste products, they are not primarily responsible for regulating blood glucose levels.

c. This choice is incorrect. The lungs are involved in oxygen and carbon dioxide exchange and are not directly involved in blood glucose regulation.

d. This choice is incorrect. The spleen is involved in immune function and blood filtration, but it does not play a central role in blood glucose regulation.

Type 1 diabetes mellitus is characterized by an autoimmune response that targets and destroys pancreatic beta cells, leading to an absolute deficiency of insulin production.

Incorrect choices:

b. This choice is incorrect. Type 2 diabetes mellitus involves insulin resistance and relative insulin deficiency, but not the autoimmune destruction of beta cells.

c. This choice is incorrect. Gestational diabetes mellitus occurs during pregnancy and is not characterized by autoimmune destruction of beta cells.

d. This choice is incorrect. Secondary diabetes mellitus is caused by other underlying medical conditions or factors and is not primarily characterized by autoimmune destruction of beta cells.
