Cushing’s Syndrome: Understanding the Causes, Symptoms, Diagnosis, and Treatment

Mar 3, 2023

If you’re confused about functional medicine certifications, look no further.

The endocrine condition known as Cushing’s Syndrome is extremely uncommon and is defined by abnormally high amounts of the hormone cortisol in the body. Cortisol is a hormone that is ordinarily produced by the adrenal glands in reaction to stress. However, in those who have Cushing’s Disease, the levels of cortisol stay high even when there is no longer any stress. If treatment is not sought for this excess cortisol, it can result in a wide variety of symptoms and may have major consequences for the patient’s health in the long term.

Causes of Cushing’s Syndrome

There are several possible causes of Cushing’s Syndrome, including:

  1. Pituitary Tumors: The most common cause of Cushing’s Syndrome is a tumor in the pituitary gland that produces too much adrenocorticotropic hormone (ACTH). This hormone stimulates the adrenal glands to produce cortisol, and an excess of ACTH can cause the adrenal glands to produce too much cortisol.
  2. Adrenal Tumors: In some cases, Cushing’s Syndrome is caused by a tumor in the adrenal gland that produces cortisol.
  3. Steroid Medication: Long-term use of steroid medications, such as prednisone, can also lead to Cushing’s Syndrome.
  4. Ectopic ACTH Syndrome: Rarely, Cushing’s Syndrome can be caused by a tumor that produces ACTH in another part of the body, such as the lungs or pancreas.

Symptoms of Cushing’s Syndrome

The symptoms of Cushing’s Syndrome can vary depending on the severity and duration of the condition. Some of the most common symptoms include:

  1. Weight Gain: Cushing’s Syndrome can cause rapid weight gain, particularly in the abdomen and face.
  2. High Blood Pressure: The excess cortisol in the body can cause high blood pressure.
  3. Fatigue: Many people with Cushing’s Syndrome experience fatigue and weakness.
  4. Diabetes: Cushing’s Syndrome can lead to high blood sugar levels and can cause or worsen diabetes.
  5. Mood Changes: Individuals with Cushing’s Syndrome may experience mood swings, irritability, and depression.
  6. Muscle Weakness: The excess cortisol can cause muscle weakness, particularly in the legs.
  7. Thin Skin and Easy Bruising: The skin may become thin and easily bruised due to the excess cortisol.
  8. Menstrual Irregularities: Women with Cushing’s Syndrome may experience irregular periods or stop menstruating altogether.

Diagnosis of Cushing’s Syndrome

The symptoms of Cushing’s Syndrome might be confusingly similar to those of other illnesses, making it difficult to correctly diagnose the condition. Yet, there are a number of tests, like the following, that can help confirm a diagnosis:

  1. Blood and Urine Tests: These tests can measure the levels of cortisol and other hormones in the body.
  2. Dexamethasone Suppression Test: This test involves taking a medication called dexamethasone, which should suppress cortisol production in healthy individuals. If cortisol levels remain high despite the medication, it suggests Cushing’s Syndrome.
  3. Imaging Tests: CT scans or MRI scans can be used to look for tumors in the pituitary or adrenal glands.
  4. Petrosal Sinus Sampling: This is a more invasive test that involves sampling blood from the petrosal sinuses to measure ACTH levels and determine the source of excess hormone production.

Treatment of Cushing’s Syndrome

Cushing’s Syndrome is a disorder that can be treated in a variety of ways, depending on the underlying cause of the condition. If the syndrome is brought on by using steroids for an extended period of time, the dosage may need to be progressively decreased or alternative treatments may be suggested.

It is possible that surgery to remove the tumor from the pituitary gland will be advised in cases when the syndrome is caused by a tumor in that gland. This type of surgery, which is referred to as transsphenoidal surgery, is often performed through the mouth or nose using specialized instruments. Following surgical procedures, patients will need to be carefully observed for the development of any potential complications, such as bleeding or infection. Following surgical removal of a tumor, radiation therapy may be suggested in some circumstances in order to further lessen the likelihood of the tumor returning.

Those who suffer from ectopic ACTH syndrome need to have the underlying ailment they are suffering from treated in order to get better. For instance, if the illness is brought on by a tumor in the lung, then surgery to remove the tumor would be considered as a treatment option. In addition, radiation therapy or chemotherapy may be utilized in an effort to assist in the reduction of ACTH levels inside the body and the size of the tumor.

When other treatments, such as surgery, are ineffective in managing the symptoms of Cushing’s syndrome, medication may be utilized to assist in the management of these symptoms. These drugs are effective because they prevent the body from producing or responding to the hormone cortisol. Ketoconazole, an antifungal medicine that can help reduce cortisol levels, is one of the medications that is frequently prescribed to patients. Other possible drugs include metyrapone, which is a drug that prevents the synthesis of cortisol, and mitotane, which is a drug that eliminates the cells in the adrenal gland that are responsible for producing cortisol.

Changes in lifestyle, such as adopting a healthier diet and getting regular exercise, may be able to alleviate some of the symptoms of Cushing’s syndrome in some patients. Patients might be given the recommendation, for instance, to consume a diet that is low in fat and sugar and high in fruits, vegetables, and grains that are whole. Participating in routine physical activity can assist in the management of weight gain as well as other symptoms associated with the illness.

In addition to receiving medical treatment, persons diagnosed with Cushing’s disease should also make sure they have access to emotional support. Managing the symptoms of a chronic ailment can be difficult, and patients may struggle with feelings of worry, sadness, and other mental health conditions. Patients and their families can find assistance in coping with the emotional burden of the condition through the use of support groups, counseling, and other resources.

Alternative Treatments 

Finding alternative and natural treatments for Cushing’s disease can be challenging as there are many different approaches. It’s important to develop a good foundational approach that addresses Cushing’s disease at the root cause.

Final Remarks

Cushing’s syndrome is a kind of Cushing’s disease, which is an uncommon but significant endocrine illness that can result in a wide variety of symptoms as well as problems. A prolonged exposure to high levels of cortisol in the body, which might be the result of an underlying health condition or the use of certain drugs, is the primary cause of the illness. The symptoms of Cushing’s syndrome might include weight gain, weakness in the muscles, and changes in mood. These symptoms can have a substantial influence on the quality of life of a patient who has the condition.

A physical exam, a review of medical history, as well as blood and urine tests, are often required to make a diagnosis of Cushing’s syndrome. Imaging procedures such as magnetic resonance imaging (MRI) and computerized tomography (CT) scans are both potential options for locating any hidden malignancies. It is possible to treat Cushing’s syndrome with surgery to remove tumors, drugs to manage symptoms, and changes to one’s lifestyle, including adopting a nutritious diet and increasing physical activity.

It is essential that you have a conversation with your healthcare provider if you are having symptoms of Cushing’s syndrome. Together, you can figure out what is causing your symptoms and devise a treatment strategy that is suitable for your condition. Many individuals are able to effectively control their symptoms and enhance their overall quality of life when they receive the appropriate management and therapy for their conditions.
