Which type of diabetes mellitus is characterized by an autoimmune destruction of pancreatic beta cells, leading to an absolute deficiency of insulin production?
Type 1 diabetes mellitus.
Type 2 diabetes mellitus.
Gestational diabetes mellitus.
Prediabetes.
The Correct Answer is A
Type 1 diabetes mellitus is characterized by an autoimmune process in which the body's immune system destroys the pancreatic beta cells responsible for producing insulin. This results in an absolute deficiency of insulin, requiring exogenous insulin administration for glycemic control.
Incorrect choices:
b. This choice is incorrect. Type 2 diabetes mellitus is characterized by insulin resistance and impaired insulin secretion, rather than 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. Prediabetes is a precursor to type 2 diabetes and involves impaired glucose tolerance, but it does not result from autoimmune destruction of beta cells.
