SHARE: Cushing's Syndrome
On this page

            The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), a component of the National Institutes of Health (NIH), is the leading federal funder of research on Cushing's syndrome.

What is Cushing's syndrome?****

Cushing's syndrome, also known as hypercortisolism, is a rare endocrine disorder caused by chronic exposure of the body's tissues to excess levels of cortisol—a hormone naturally produced by the adrenal gland. Neurological symptoms include muscle weakness and difficulties with memory and concentration.

Common symptoms of Cushing's syndrome include:

Upper body obesity
	Severe fatigue
	High blood pressure
	Backache

Elevated blood sugar
	Easy bruising
	Bluish-red stretch marks on the skin

In women, there may be increased growth of facial and body hair, and menstrual periods may become irregular or stop completely. Treatments for the disorder are available but Cushing's syndrome can be fatal if not treated.

Cushing's syndrome most often affects adults but can occur in children. It affects about as three times as many women as men.

Learn About Clinical Trials

Clinical trials are studies that allow us to learn more about disorders and improve care. They can help connect patients with new and upcoming treatment options.

How can I or my loved one help improve care for people with Cushing's syndrome?

Cushing's syndrome is considered a rare disease, which means there is often not much information known about the disorder. This is usually the case because doctors and researchers do not see enough patients with Cushing's syndrome, which makes it hard to learn from them through observations or large studies.

Consider participating in a clinical trial so clinicians and scientists can learn more about Cushing's syndrome and related disorders. Clinical research uses human volunteers to help researchers learn more about a disorder and perhaps find better ways to safely detect, treat, or prevent disease.

All types of volunteers are needed—those who are healthy or may have an illness or disease—of all different ages, sexes, races, and ethnicities to ensure that study results apply to as many people as possible, and that treatments will be safe and effective for everyone who will use them.

For information about participating in clinical research visitNIH Clinical Research Trials and You. Learn about clinical trials currently looking for people with Cushing's syndrome atClinicaltrials.gov.
