Cushing Syndrome: Causes, Symptoms and Treatment

Why in News ?

Recent medical studies are exploring new treatment options for Cushing Syndrome, including :

• New drugs that control cortisol production
• Targeted hormonal therapies
• Improved surgical techniques

These developments are expected to make the treatment of this disease more effective in the future.

Cushing Syndrome

Cushing Syndrome is a hormonal disorder that occurs when the body is exposed to high levels of the hormone cortisol for a long period of time.

Cortisol is often called the “stress hormone” because it helps the body respond to stress.

Cortisol is produced by the adrenal glands, which are small glands located above the kidneys. This hormone regulates several important functions in the body, such as:

• Controlling blood pressure
• Regulating metabolism
• Influencing the immune system
• Managing the body’s response to stress

When the body produces too much cortisol, it can lead to several physical and psychological health problems, a condition known as Cushing Syndrome.

Major Causes of Cushing Syndrome

There are two main causes of Cushing Syndrome:

1. Long-term use of steroid medications

The most common cause is the long-term use of corticosteroid (steroid) medications. These drugs are commonly prescribed for conditions such as:

• Asthma
• Autoimmune diseases
• Arthritis
• After organ transplantation

If these medicines are taken in high doses or for a long time, they can increase cortisol levels in the body.

2. Excess cortisol production by the body

In some cases, the body itself produces too much cortisol. The main causes include:

• Tumor in the pituitary gland (called Cushing Disease)
• Tumor in the adrenal gland
• Tumors in other parts of the body that produce ACTH hormone

Most of these tumors are benign (non-cancerous).

Symptoms and Signs of Cushing Syndrome

The symptoms of Cushing Syndrome usually develop gradually and may resemble other diseases.

Physical symptoms

• Weight gain, especially around the abdomen and face
• Round and swollen face (Moon face)
• Fat accumulation between the shoulders (Buffalo hump)
• Thin and fragile skin
• Easy bruising
• Slow healing of wounds
• Purple stretch marks on the abdomen, thighs, breasts, or arms

Skin and hormonal symptoms

• Acne
• Excess hair growth on the face or body in women
• Irregular menstrual cycles in women
• Reduced libido and fertility problems in men

Other health problems

• High blood pressure
• Increased blood sugar levels
• Risk of diabetes
• Weak bones (osteoporosis)
• Frequent fractures

Mental and neurological symptoms

• Anxiety and irritability
• Depression
• Mood swings
• Sleep problems
• Memory issues

Risk Factors

In naturally occurring cases of Cushing Syndrome:

• Women are affected more than men
• It is most commonly seen in people between 30 and 50 years of age

However, when caused by steroid medications, it can occur at any age.

Diagnosis

Doctors use several tests to confirm Cushing Syndrome, including:

• Blood tests to measure cortisol levels
• 24-hour urine test
• Saliva cortisol test
• Dexamethasone suppression test
• MRI or CT scans to detect tumors

Treatment

Treatment for Cushing Syndrome depends on the underlying cause, and the main goal is to reduce cortisol levels to normal.

1. Adjustment of medications

If steroid medications are the cause, doctors gradually reduce the dosage under medical supervision.

2. Surgery

If a tumor is producing excess cortisol, surgery is usually the first treatment option to remove the tumor.

3. Radiation therapy

If surgery is not possible or the tumor cannot be completely removed, radiation therapy may be used.

4. Medications

Certain drugs are prescribed to reduce cortisol production in the body.
