Pituitary apoplexy is a serious condition that results from the sudden bleeding in the pituitary gland. This condition is also known as pituitary gland infarction, pituitary hemorrhage, or pituitary necrosis. It can lead to a sudden and severe headache, vision problems, hormonal imbalances, and even unconsciousness. In some cases, surgery is required to relieve the pressure on the pituitary gland. Other possible synonyms for pituitary apoplexy include pituitary stroke, pituitary gland rupture, and pituitary gland ischemia. It is important to seek medical attention immediately if any of the symptoms associated with pituitary apoplexy occur.
