Pituitary tumors in women can be fatal. First of all, in terms of occupational effects, pituitary tumors grow and gradually develop headaches, nausea and vomiting. If the pituitary tumor grows out of the saddle septum, it will cause a series of clinical symptoms, including visual impairment and loss of visual field, and severe compression of the hypothalamus and the brainstem and other neural tissues. More serious is the endocrine symptoms, because these endocrine functions can affect the normal development and function of the human body, for example, growth hormone adenoma can cause thickening of female terminal limbs; adrenocorticotropic hormone adenoma can cause disorder of corticotropin secretion in the human body, forming a series of disorders. If a pituitary tumor is particularly large, it can compress the pituitary stalk and cause urinary collapse, making it more likely to cause death.
