OHSU Northwest Pituitary Center


The OHSU Northwest Pituitary Center is the West Coast’s most comprehensive center and one of the largest in the country. Led by internationally recognized pituitary expert, Maria Fleseriu, M.D., F.A.C.E., the OHSU Northwest Pituitary Center offers unmatched expertise and resources to people with pituitary gland conditions and neuroendocrine disorders (problems with the hormone secretion system).

At the OHSU Northwest Pituitary Center, we perform more pituitary diagnoses, second opinions and pituitary gland procedures of all types than any other medical center in the region. Our experts treat simple and complicated pituitary conditions, and see more than 500 new patients from across the country each year.

We're part of OHSU, Oregon's only health and research university, so you have access to many clinical trials (research studies of the latest pituitary disease treatments and procedures). We were a major contributor to clinical studies that resulted in two new FDA-approved, first in their class treatments. If you have a pituitary tumor or pituitary gland disorder, the OHSU Northwest Pituitary Center can provide all the care you need in one place.

About pituitary gland disorders


Pituitary gland disorders are not common, but can be serious if they are not diagnosed and treated. Some pituitary gland disorders do not cause complications, but other pituitary disorders can cause serious problems, including blindness and death.

Because pituitary diseases have many different symptoms, they can be difficult to diagnose and treatment can be complicated.
