The pituitary gland is an important secretion gland in the body, capable of secreting seven hormones, including thyroid stimulating hormone, adrenocorticotropic hormone, follicle stimulating hormone, luteinizing hormone, growth hormone, prolactin and melanocortin, all of which are secreted by the pituitary gland. Inadequate secretion of the pituitary gland generally occurs when there is an abnormal function of the pituitary gland, resulting in varying degrees of deficiency of the above seven hormones. The most common cause is maternal postpartum pituitary necrosis, which can cause hypopituitarism in women, mostly caused by necrosis of the pituitary gland when hemorrhage or other complications occur during childbirth. In addition, pituitary adenomas, craniopharyngiomas, and pituitary surgery can cause hypopituitarism, resulting in various degrees of deficiency of the seven hormones, which can manifest clinically as pituitary hormone deficiency. Growth hormone deficiency can lead to dwarfism in children; gonadotropin deficiency can lead to gonadotropin deficiency, resulting in a series of sexual dysfunction; and thyrotropin deficiency can lead to secondary hypothyroidism. In addition adrenocorticotropic hormone deficiency will result in weakness, fatigue, nausea, vomiting and postural hypotension, and other symptoms of different degrees of glucocorticoid and saline corticoid deficiency.
