Lisa Cuddy’s medical specialty in House M.D. was endocrinology.
Before and during her administrative career, Cuddy was presented as an endocrinologist. She became the dean of medicine at Princeton-Plainsboro Teaching Hospital and was responsible for managing the institution, its physicians, and its frequently troublesome diagnostic department.
Her specialty is an important detail because Cuddy is often remembered primarily as House’s supervisor and hospital administrator. The series also used her medical background to place her in clinical conversations, although her executive responsibilities usually dominated her scenes.
Endocrinology concerns hormones and the glands that produce them, including the thyroid, pancreas, pituitary, and adrenal glands. It is therefore distinct from cardiology, neurology, and dermatology. Cuddy’s professional role shifted toward leadership, but the show continued to identify her as an endocrinologist.
