This SOP covers pathology of the pituitary and also pathology of the hypothalamus where it causes a deficiency in pituitary hormone production.
The pituitary produces a range of hormones: growth hormone; thyroid stimulating hormone; adrenocorticotrophic hormone; follicle stimulating hormone; lutenising hormone; prolactin; antidiuretic hormone/vasopressin; and oxytocin. Hypopituitarism can cause a deficiency in one or more or all pituitary hormones, with a wide range of possible clinical manifestations.

Endocrinological specialist opinion together with the requisite abnormal blood hormone levels is required.
Are there sub-factors that require specific information? – No.
