"Understanding Cushing’s Syndrome: Causes, Symptoms & Treatments"

Cushing’s syndrome is an uncommon condition that is caused by high levels of corticosteroid hormones (particularly cortisol) in the body. This hormonal disorder, named after Harvey Cushing who first identified it in 1932, can occur as a result of a variety of factors, but it is most commonly a side effect of long-term steroid medication use. It can also be triggered by a tumor or other abnormal growth on the adrenal or pituitary glands.

Causes of Cushing’s Syndrome

The adrenal glands, located above the kidneys, are responsible for the production of cortisol. This hormone aids in managing stress, maintaining cardiovascular function, reducing inflammation, and regulating the metabolism. However, when the body generates too much cortisol, Cushing’s syndrome can occur.

The most common cause of Cushing’s syndrome is the use of oral corticosteroid medication, often used to treat conditions like lupus, asthma, and rheumatoid arthritis. This form of Cushing’s syndrome, referred to as exogenous Cushing’s syndrome, can develop from high doses of corticosteroids over extended periods of time.

Endogenous Cushing’s syndrome occurs when the body produces too much cortisol. The cause here is usually a tumor in the pituitary gland (Cushing’s disease), the adrenal gland, or a tumor elsewhere in the body that secretes ACTH (adrenocorticotropic hormone), which in turn stimulates the adrenal glands to produce cortisol.

Symptoms of Cushing’s Syndrome

Symptoms of Cushing’s syndrome vary but most people with the disorder experience rapid weight gain in the face, abdomen, and chest. Other common symptoms include pink or purple stretch marks, thinning skin that bruises easily, acne, fatigue, muscle weakness, high blood pressure, high blood sugar, increased thirst and urination, bone loss, depression, and cognitive problems. Due to the variety of symptoms, diagnosis can be challenging and frequently comes after numerous medical consultations.

Treatment for Cushing’s Syndrome

The treatment for Cushing’s syndrome primarily focuses on reducing the high level of cortisol in the body. If the cause is long-term use of corticosteroid medication, doctors may attempt to reduce the dosage or switch to a non-steroidal medication. However, this approach must be conducted under close medical supervision because of the risk of adrenal insufficiency.

If the cause is a tumor, the ideal treatment is usually surgical removal. If surgery is not an option, medications or radiation may be used to reduce cortisol production or block its effects. After successful treatment, most symptoms of Cushing’s syndrome will go away, though recovery may take some time.


Cushing’s syndrome can significantly affect a person’s quality of life, both physically and emotionally. However, with the correct diagnosis and treatment, most people successfully manage the disorder and can expect a return to normal cortisol production and a significant reduction or elimination of their symptoms. Regular follow-ups with healthcare professionals are essential to monitor recovery and ensure the condition does not recur.

Frequently Asked Questions

  1. What is the main cause of Cushing’s syndrome?

    The most common cause is prolonged usage of corticosteroid medicines. However, it can also be caused if your body makes too much cortisol.

  2. Can Cushing’s syndrome be cured?

    Yes, most people with Cushing’s syndrome can be cured or at least manage their symptoms with the right treatment, often through reducing cortisol levels or removing the root cause.

  3. What are the early signs of Cushing Syndrome?

    Early signs include high blood pressure, obesity that mainly affects the chest and abdomen, but not the arms and legs, purple or pink stretch marks, and being easily bruised.

  4. How serious is Cushing’s syndrome?

    If left untreated, Cushing’s syndrome can lead to serious health complications such as high blood pressure, diabetes, depression, bone loss, and kidney stones.

  5. Who can get Cushing’s syndrome?

    It can affect anyone but is most common among adults aged 20 to 50. People taking corticosteroid medication for a long period are also at a higher risk.
