Lewis Blevins, MD

Professor

Dr. Lewis Blevins is an endocrinologist specializing in evaluating and managing pituitary and hypothalamus disorders, including acromegaly, prolactinoma and other pituitary tumors, diabetes insipidus, hypopituitarism and growth hormone deficiencies. As medical director of the California Center for Pituitary Disorders at UCSF Medical Center, he guides a team providing comprehensive, state-of-the-art care. He has a special interest in Cushing's syndrome, also known as hypercortisolism, and has edited a book on the subject.

In his research, Blevins is interested in evaluating new methods for diagnosing Cushing's syndrome. He also studies the factors that medical professionals can use to predict whether treating pituitary tumors with surgery or other methods will succeed.

Blevins earned a medical degree at Quillen College of Medicine at East Tennessee State University and completed a residency in internal medicine at the University of Alabama at Birmingham Hospitals. After completing a fellowship in endocrinology at the Johns Hopkins Hospital, he served on the faculty at Emory University for four years and at Vanderbilt University for nine years.
