Pituitary gland help control the following body processes: Some of the diseases involving the pituitary gland are: All of the functions of the pituitary gland can be adversely affected by an over- or under-production of associated hormones. The pituitary gland is important for mediating the stress response, via the hypothalamic–pituitary–adrenal axis (HPA axis) Critically, pituitary gland growth during adolescence can be altered by early life stress such as childhood maltreatment or maternal dysphoric behavior. It has been demonstrated that, after controlling for age, sex, and BMI, larger quantities of DHEA and DHEA-S tended to be linked to larger pituitary volume. Additionally, a
Pituitary apoplexy proportion of pituitary tumors eventually undergoes apoplexy. In an analysis of incidentally found pituitary tumors, apoplexy occurred in 0.2% annually, but the risk was higher in tumors larger than 10 mm ("macroadenomas") and tumors that were growing more rapidly; in a meta-analysis, not all these associations achieved statistical significance. The majority of cases (60–80%) are not precipitated by a particular cause. A quarter has a history of high blood pressure, but this is a common problem in the general population, and it is not clear whether it significantly increase the risk of apoplexy. A number of cases has been reported
