Treatment of Hypopituitarism Hypopituitarism requires early diagnosis, which can be difficult unless care is taken when documenting patients' history. Women tend to present earlier than men because of menstrual abnormalities. The many causes of hypopituitarism have to be dealt with individually; thus, a pituitary tumour may be treated by surgery, radiotherapy, or medical treatment.
