Cushing's syndrome is a rare but serious medical condition characterized by an excess of the hormone cortisol in the body. This condition can lead to a wide range of symptoms and health complications, so it is essential for individuals to have a clear understanding of its causes, symptoms and treatment options. In this article, we turn to Harvard Health Publishing to answer some common questions about Cushing's syndrome and provide valuable insight and information to those affected by or interested in the condition.


Harvard Health Publishing answers common questions about Cushing's syndrome.

What is Cushing's syndrome?
Cushing's syndrome, also known as hypercortisolism, is a medical disorder caused by long-term exposure to high levels of the hormone cortisol. This can be the result of a variety of factors, including the use of corticosteroids, tumors in the adrenal glands or, in rare cases, tumors of the pituitary gland.

What are the symptoms of Cushing's syndrome?
Cushing's syndrome can present with a wide range of symptoms, which may include weight gain, especially in the abdomen and face (moon face), muscle weakness, easy bruising, high blood pressure and mood disorders. Other common symptoms include thinning skin, stretch marks, and increased thirst and urination.

What causes Cushing's syndrome?
The most common cause of Cushing's syndrome is long-term use of corticosteroids such as prednisone for conditions such as asthma, rheumatoid arthritis, or lupus. However, tumors of the adrenal glands or pituitary gland, which excessively produce cortisol, can also be the cause. In some cases, tumors elsewhere in the body can produce adrenocorticotropic hormone (ACTH), which triggers the adrenal glands to produce excess cortisol.

How is Cushing's syndrome diagnosed?
Diagnosing Cushing's syndrome involves a number of tests and evaluations. These usually include blood tests to measure cortisol levels, urine tests to assess cortisol excretion, and imaging studies such as CT scans or MRIs to locate any tumors. A dexamethasone suppression test may also be performed to confirm the diagnosis.

What treatment options are available for Cushing's syndrome?
The choice of treatment for Cushing's syndrome depends on its underlying cause. If corticosteroid use is the result, tapering off treatment may help. In other cases, surgical removal of tumors in the adrenal glands or pituitary gland may be necessary. In some situations, radiation therapy or medications to block excess cortisol production may also be considered.

Can Cushing's syndrome be cured?
The outcome of treatment for Cushing's syndrome varies depending on the cause and individual response to therapy. If the condition is the result of medication, discontinuation often leads to improvement. Surgical removal of tumors can also lead to a cure in some cases. However, individuals may require ongoing monitoring and management to control cortisol levels and address any persistent symptoms.

What are the long-term effects of Cushing's syndrome?
If left untreated, Cushing's syndrome can lead to serious health complications, including diabetes, high blood pressure, osteoporosis, and increased susceptibility to infections. It can also have psychological effects due to the physical changes it causes, such as weight gain and facial swelling.

Is there research into Cushing's syndrome?
Yes, researchers are constantly studying Cushing's syndrome to better understand its causes and develop more effective treatments. Harvard Health Publishing recommends that you stay informed about the latest research and consult with medical professionals for the most up-to-date information and treatment options.

Cushing's syndrome is a complex medical condition that can significantly affect a person's health and well-being. It is essential that individuals and their healthcare providers are well informed about its causes, symptoms and treatment options. By addressing common questions about Cushing's syndrome, Harvard Health Publishing provides valuable insights into the condition and empowers individuals to seek early diagnosis and appropriate treatment to improve their quality of life. If you suspect you may have Cushing's syndrome, consult a healthcare professional for a thorough assessment and guidance on how to manage the condition.
