What is affected when panhypopituitarism happen?

Subtle: In an adult, just feeling unwell, loss of sexual function / failure of lactation, "the blahs" -- the symptoms are subtle enough that many of these people end up being sent for mental health checks before a clever physician finally notices the lost pituitary gland. If a mass, headaches & visual field cuts. Have a high index of suspicion, and good luck.
