Cushing's Disease

Cushing’s Disease Experts

Cushing's disease refers to an endocrine disorder where too much cortisol is produced by the body. It's sometimes difficult for physicians to determine what organ is responsible for the elevated cortisol levels.

At Stony Brook Medicine, we perform what's known as an Inferior Petrosal Sinus Sampling (IPSS), an invasive procedure in which adrenocorticotropic hormone (ACTH) levels are sampled from the veins that drain the pituitary gland to determine a Cushing's disease diagnosis.
