Generalized hypopituitarism

Big picture

Generalized hypopituitarism means partial or complete failure of anterior pituitary hormone secretion, usually due to a pituitary or hypothalamic lesion. In exams, think of it as multiple endocrine glands becoming “understimulated” at the same time:

Pituitary failure → ↓ trophic hormones → ↓ adrenal, thyroid, gonadal function ± growth hormone deficiency.

The most dangerous deficiency is adrenocorticotropic hormone (ACTH) deficiency, because it causes secondary adrenal insufficiency and can lead to hypoglycemia, shock, coma, and death, especially during infection, surgery, or trauma.

The examiner usually wants you to know:
