Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Ahmed Elsaiey, MBBCH [2]

Overview

Hypopituitarism can be classified on the basis of location of pathology into primary or secondary hypopituitarism. It can also be classified on the basis of the extent of gland involved into partial or complete glandular involvement.

Classification

Hypopituitarism can be classified on the basis of location of pathology and the extent of glandular involvement:^[1]

Classification on the basis of anatomical location:

Primary hypopituitarism: Represents intrinsic pathology in pituitary and decreased pituitary hormone levels

Secondary hypopituitarism: Represents pathology in hypothalamus and decreased hypothalamic hormone levels

Classification on the basis of extent of glandular involvement

Partial hypopituitarism: Means deficiency of one or more than one hormones (can be anterior or posterior pituitary gland lobe)

Complete/Panhypopituitarism: Means deficiency of all of the pituitary hormones (both anterior and posterior lobes)
