Cushing Syndrome
What is Cushing Syndrome?
Cushing Syndrome is a rare condition where the body is exposed to high levels of the hormone cortisol for a prolonged period. Cortisol, produced by the adrenal glands, plays a role in regulating important functions such as blood sugar, metabolism, and the immune system. Elevated cortisol levels can lead to different health issues.
Cushing Syndrome can be caused by tumors in the adrenal or pituitary glands, or by using steroid medications for a long time. Signs can include gaining weight, skin getting thinner, having high blood pressure, and changes in mood. This Syndrome is diagnosed with tests such as blood or urine tests, and imaging scans. The cause determines the treatment, but common ways to manage the condition include surgery, medication, or reducing steroid use.
Symptoms of Cushing Syndrome
The symptoms of Cushing Syndrome can vary depending on the severity of the condition, but some of the most common signs include:
Weight gain
Cushing Syndrome often leads to weight gain, especially in the upper body, face, and abdomen. The reason for this is that too much cortisol is impacting how fat is stored in the body. People might see that their body shape is changing, and they are gaining more weight around their stomach and face, making them look puffy.
Round face
A common symptom of Cushing Syndrome is a “moon face,” in which the face looks more circular and plumper. Excess cortisol causes fat to build up in the face, making it look puffy and swollen. This can make the face look exaggerated and uneven.
Thinning skin
Too much cortisol can make the skin thinner and weaker. This makes it easier for the skin to get bruises or cuts, even from small bumps or cuts. The skin can also become less firm, making wrinkles and stretch marks more visible as signs of aging.
Muscle weakness
People with Cushing Syndrome often have trouble using their muscles, especially in their arms and legs. This can make it hard to do things every day that need strength. Cortisol can make muscles feel tired or less strong because it affects muscle tissue and breaks down proteins.
High blood pressure
Cortisol is important for controlling blood pressure. Too much cortisol can cause high blood pressure. Over time, this can put pressure on the heart and blood vessels, making it more likely to develop heart disease, stroke, and other problems with the heart and blood circulation.
Mood changes
Cushing Syndrome can cause big changes in mood because of the effect of high cortisol levels on the brain. People might feel more worried, cranky, or sad. These feelings can make it hard to deal with stress or stay positive in everyday life.
Fatigue
Cushing Syndrome often causes long-term tiredness or fatigue. Too much cortisol can disturb the body’s regular sleep pattern and energy levels. Therefore, many people often feel very tired all the time, even after sleeping all night, which can make it hard for them to concentrate and be productive during the day.
Increased thirst and urination
Too much cortisol can cause problems with your kidneys, making you feel more thirsty and needing to pee more often. People might start drinking more and needing to go to the bathroom more often. Not managing your fluid intake can cause dehydration.
Irregular menstrual cycles
Cushing Syndrome can lead to irregular periods in women. Periods may happen less often, be lighter, or stop completely. High cortisol levels disrupt the balance of other hormones that help control the menstrual cycle, which can affect reproductive health and fertility.
Causes of Cushing Syndrome
There are several potential causes of Cushing Syndrome, each leading to excess cortisol production:
Pituitary adenomas
The main reason for Cushing Syndrome is a non-cancerous growth in the pituitary gland called Cushing’s disease. This growth makes the pituitary gland release too much adrenocorticotropic hormone (ACTH), which tells the adrenal glands to make more cortisol. The excessive production of cortisol causes the symptoms of the syndrome.
Adrenal tumors
Cushing syndrome can also be caused by tumors in the adrenal glands that make too much cortisol. These growths can be harmless or cancerous, and they make too much cortisol which messes up the body’s normal hormone levels. Therefore, the body shows signs of having too much cortisol, such as gaining weight and having high blood pressure.
Ectopic ACTH syndrome
Some cancers, like lung cancer or small cell tumors, can make ACTH. This makes the adrenal glands produce more cortisol. This is called ectopic ACTH syndrome. The tumors can make too much ACTH, which can increase cortisol levels and make people have signs of Cushing Syndrome like a round face and weak muscles.
Corticosteroid medication
Using corticosteroid drugs for a long time to treat conditions like asthma, arthritis, or lupus can cause iatrogenic Cushing Syndrome. Synthetic steroids act like cortisol in the body. Using them for a long time can make cortisol levels go up, causing symptoms like gaining weight, thinning skin, and mood changes.
Diagnosis of Cushing Syndrome
To diagnose Cushing Syndrome, doctors rely on several tests to confirm elevated cortisol levels and determine the cause:
Urine test
The 24-hour urine test checks how much cortisol your body makes in one day. Doctors can test if your cortisol levels are higher than normal by collecting all of your urine for 24 hours. This easy test can show if too much cortisol is causing symptoms of Cushing Syndrome.
Blood tests
Blood tests are used to measure cortisol levels at various times during the day. Cortisol levels are usually higher in the morning and lower at night. If your test results are not normal, it may mean you have Cushing Syndrome. This test assists doctors in understanding how your cortisol levels change.
Saliva test
A saliva test taken at night checks cortisol levels when they are supposed to be naturally low. Cushing syndrome may be indicated if cortisol levels remain high at night. This exam is simple because it only needs a small amount of saliva sample.
Imaging tests
MRI or CT scans are used to find tumors in the pituitary or adrenal glands that could be causing too much cortisol. These tests help doctors find the exact place of the problem so they can decide on the best treatment.
Dexamethasone suppression test
In this test, you take a synthetic steroid called dexamethasone to see how your body reacts. Normally, dexamethasone lowers cortisol levels, but if your body doesn’t respond as expected, it may indicate Cushing Syndrome. This test helps confirm the diagnosis.
Treatment Options for Cushing Syndrome
The kind of treatment for Cushing Syndrome varies depending on the cause of the condition. Here are a few common ways to treat it:
Surgery
The best treatment for Cushing Syndrome caused by a tumor is usually to remove the tumor. Surgery for pituitary tumors is usually done through the nose, while surgery for adrenal tumors is done on the abdomen. Surgery can lower cortisol levels, but it may take time to fully recover. It’s important to get follow-up care to check hormone levels and prevent the condition from coming back.
Radiation therapy
If surgery cannot remove a tumor that causes Cushing Syndrome, radiation therapy is another choice. By using focused radiation, the tumor can be made smaller and cortisol production can be reduced gradually. This treatment is commonly used for pituitary tumors that are hard to completely remove. It may take several weeks or months to see results, but it can effectively control symptoms.
Medications
Some medications can stop the body from making too much cortisol or reduce its effects. Commonly used drugs include ketoconazole, metyrapone, and mitotane. These medications are very useful for people who are not able to have surgery or need temporary relief while waiting for other treatments to take effect.
Reducing corticosteroid use
If using corticosteroid medication for a long time causes Cushing Syndrome, doctors may reduce the dose slowly or try a different treatment. It is necessary to gradually reduce these medications to prevent withdrawal symptoms or worsening health problems. Always listen to the advice of your doctor when making changes to your medications.
Lifestyle changes
Embracing a healthy way of living can aid in controlling symptoms of Cushing Syndrome and enhancing general health. It’s important to eat a variety of foods, exercise regularly, and handle stress effectively. These changes won’t heal the condition, but they can help with treatment, increase energy, and lower the chance of problems like high blood pressure or diabetes.
