Diabetes Mellitus of Pituitary Origin: A Case Report.

We describe the case report of 36-year-old female who presented to the emergency department with diabetic ketoacidosis. On detailed clinical examination, coarse facial features in the form of large fleshy nose, thick lips, prognathism, and thickening of hands and feet were noticed, suggestive of acromegaly. Subsequently, she was diagnosed with acromegaly due to somatotropinoma. Impaired glucose tolerance and diabetes mellitus are frequently associated with acromegaly. Persistent growth hormone excess impairs insulin sensitivity, increases gluconeogenesis, reduces glucose uptake in adipose tissue and muscle, and alters pancreatic β-cell function. Rarely, diabetic ketoacidosis can be the presenting manifestation, as seen in this case. © Touch Medical Media 2021.
