Pituitary adenomas are benign tumors of the anterior portion of the pituitary
gland (adenohypophysis), representing the 25% of all the tumor
alterations. Pituitary adenomas are classified by the type of hormone secreted,
cellularity, size, and structural alterations by the hormonal segregation. The
diagnosis consists on the histopathological identification of cell types and the
image-guided by magnetic resonance or tomography; the treatment can be both
pharmacological and surgical. Metabolic Syndrome is the set of clinical
conditions that increase the risk of cardiovascular diseases with an estimated
prevalence of 25% worldwide. The alterations of metabolic syndrome are
obesity, hypertension, dyslipidemia, insulin resistance, and diabetes mellitus
type II. Pituitary adenomas and metabolic syndrome have an important
relationship, hormone-secreting by pituitary adenomas affects a myriad of
signaling pathways, which allows a favorable environment for the appearance of
the metabolic syndrome. Moreover, patients with pituitary adenomas are shown to
have an improvement in metabolic parameters after the medical/surgical
treatment. The objective of this review is to explore the possible mechanisms
through which PAs contributes to MetSx.
