What Causes High Cortisol Levels

High Cortisol Signs And Symptoms In Women

Cushing Syndrome – causes, symptoms, diagnosis, treatment, pathology

When cortisol production is balanced, levels of the hormone naturally rise and fall during the day. These patterns are tightly connected to your circadian rhythm sleep/wake cycle.

Cortisol levels are usually lowest between midnight and 4:00 AM and then gradually increase until around 8:00 AM. Rising cortisol helps you to wake up and start the day. After 8:00 AM, cortisol declines incrementally throughout the day to gradually prepare you for sleep.

This daily rhythm is the norm unless you encounter a stressful event. In response to danger, your body temporarily raises levels of cortisol and adrenaline to handle the stressful event. After the stressors have passed, cortisol and adrenaline levels return to normal.

Thats the way its supposed to work. Yet when chronic stress leads to unnaturally high cortisol levels, it creates a state of adrenal imbalance that often triggers a cascade of adrenal-related symptoms:

  • Thyroid imbalances

Radiation Therapy For Tumors

If your healthcare provider is unable, for whatever reason, to remove a tumor on your pituitary gland, they may suggest radiation therapy. This therapy takes place over six weeks. They could also suggest stereotactic radiosurgery. Here, you receive one dose of radiation using a three-dimensional coordinates system to minimize radiation exposure to surrounding tissue.

When Should I See My Doctor About My Cortisol Levels

If you experience symptoms of Cushings syndrome or adrenal insufficiency, contact your healthcare provider.

If youre concerned about your daily stress levels, talk to your provider about steps you can take to minimize your stress and stay healthy.

A note from Cleveland Clinic

Cortisol is an essential hormone that impacts several aspects of your body. While there are several things you can do to try to limit your stress, and therefore manage your cortisol levels, sometimes having abnormally high or low levels of cortisol is out of your control.

If you experience symptoms of high or low cortisol levels, such as weight gain or loss and high or low blood pressure, respectively, its important to contact your healthcare provider. They can run some simple tests to see if your adrenal glands or pituitary gland are responsible for your symptoms.

The body system that controls hormone production is the endocrine system.

Within this system, the glands work together and produce different types of hormones.

The hormones that one gland produces can directly affect the hormone production of other glands.

These glands include the adrenal glands, pituitary gland, thyroid gland, parathyroid glands, pancreas, ovaries, and testicles.

Cortisol helps to regulate how the body turns proteins, carbohydrates, and fat from food into energy.

When cortisol levels are persistently high, Cushings syndrome can result.

Negative Effects Of High Cortisol

Elevated cortisol levels

Adrenal imbalance in women tends to peak between the ages of 35 and 55 and most often shows up in one of the following ways:

  • Youre always active and feel wired. Your system is constantly fueled by adrenaline and cortisol to create what feels like a continual state of hyper-energy. Yet you often feel drained.
  • You cant get up in the morning but you cant sleep at night. Your natural 24-cycle of energy and relaxation is off-balance. If youre able to fall asleep, you may wake up in the middle of the night fully alert.
  • You have no energy period. You feel exhausted all the time. Even getting out of bed often feels like a challenge. You may also experience intense cravings and unexplained weight gain.

Adrenal imbalance may be a factor in many other serious conditions, including fibromyalgia, hypothyroidism, chronic fatigue syndrome, depression, arthritis, anxiety at night and more.

What Does Low Cortisol Levels Mean

Low cortisol levels, also known as hypocortisolism, can be caused by multiple issues. Some factors that can contribute to low cortisol levels include Addisons disease, an autoimmune disorder which attacks the adrenal glands, impairing cortisol production, an underactive pituitary gland or adrenal fatigue. Over days and weeks of low cortisol levels, negative effects can be experienced as a side effect of these abnormal levels.

What Happens When You Produce Too Much Or Little Cortisol

The body usually produces the right amount of cortisol. In a condition such as Cushings syndrome, it produces too much. In a condition such as Addisons disease, it produces too little.

Symptoms of too much cortisol include:

  • weight gain, particularly around the abdomen and face
  • thin and fragile skin that is slow to heal
  • for women, facial hair and irregular menstrual periods

Symptoms of not enough cortisol include:

If you experience any of these symptoms, your doctor may suggest you have a blood test to measure your cortisol levels.

Reset Your Circadian Rhythms

We all know good sleep is paramount to good health. One reason sleep matters so much is that it involves the fluctuation of and connection between melatonin and cortisol, two hormones directly related to stress and overall bodily health. Practice healthy sleep habits by sleeping and waking at the same time each day, striving for at least 7 hours of uninterrupted rest, and limiting electronics use in the hour before bedtime. Also try to get plenty of sunshine in the morning and at midday to further stabilize your bodys circadian rhythms.

These negative effects also often come with their own consequences. For example, increased abdominal fat is associated with a greater amount of health problems than fat deposited in other areas of the body. Some of the health problems associated with increased stomach fat include an increased risk for heart attacks, strokes, metabolic syndrome, higher levels of bad cholesterol , and lower levels of good cholesterol .

Cortisol is important for your body to function normally, but too much cortisol can be bad for your health.

Chronic high cortisol levels can also lead to a condition known as Cushing syndrome. Causes can include adrenal tumors or the prolonged use of glucocorticoids. Symptoms of Cushing syndrome can also include high blood sugars with increased thirst and urination, osteoporosis, depression, and more frequent infections.

What Does The Structure Of The Cardiovascular System Look Like

Your heart is a very important part of your cardiovascular system because it powers the system that brings your cells what they need and takes away what they dont. Your heart connects to a network of blood vessels all over your body.

If youve ever seen water or sewer pipes under the street, you know they are very large. These pipes lead to smaller and smaller pipes that carry water into your house and sewage out of your house. Similar to the main pipes under the street, the blood vessels going into and out of your heart are the largest in your body. They connect to smaller and smaller blood vessels as they get farther away from your heart to deliver oxygen and remove waste throughout your entire body. Capillaries, the tiniest of blood vessels, transfer oxygen, nutrients and waste between your blood vessels and your tissue cells.

What Is The Cardiovascular System

Cortisol Hormone: Its Role In Stress, Inflammation, And Weight Gain ...

Your heart and many blood vessels in your body make up your cardiovascular system or circulatory system. Your heart uses the far-reaching, intricate network of blood vessels to deliver oxygen and other necessary things to your whole body. This network also removes the things your body doesnt need and takes them to organs that can get rid of the waste. Your blood carries the oxygen, nutrients and waste through your entire body.

Medications To Control Cortisol Production

Your healthcare provider may also suggest the use of medication to modify the excessive production of cortisol. Those undergoing surgery may also be prescribed medications beforehand to improve their symptoms beforehand and also minimize any possible risks during the procedure. These medications may have side effects, however. These include headaches, nausea, vomiting, fatigue, high blood pressure, and swelling. Some medications may have more serious side effects that include liver toxicity and neurological issues.

The Cortisol Rhythm Plays To Its Own Tune

Aside from intermittent stressors that trigger the fight-or-flight response , did you know that your bodyâs cortisol production follows its own circadian rhythm?

Normal individuals with a healthy functioning cortisol rhythm have cortisol levels that reach their lowest point at midnight, followed by a build up overnight to peak first thing in the morning. Cortisol volume is typically high when you wake up and surges for 50-60% in the first 30-45 minutes after youâve awakened. This is called the cortisol awakening response .

The cortisol load then drops rapidly past this early morning spike before gradually declining throughout the day to reach its minimum level around bedtime so you can wind down and go to sleep.

Scientists call this everyday phenomenon the cortisol diurnal rhythm or cortisol circadian rhythm. If youâre wondering who is the conductor of this rhythm, the suprachiasmatic nucleus in the hypothalamus, which is also the principal circadian clock of the brain, acts as the catalyst for cortisol production via the HPA axis.

Across 24 hours, the normal range for healthy salivary cortisol levels looks like this:

  • 7 a.m. to 9 a.m.: 100-750 ng/dL
  • 3 p.m. to 5 p.m.:< 401 ng/dL
  • 11 p.m. to 12 a.m.:< 100 ng/dL

If your cortisol test results exceed the bracketed values above, youâre likely facing an unhealthy cortisol surplus.

What Can Cause Abnormal Cortisol Levels

Cortisol levels rise and fall naturally throughout the day. Absent a threat, your cortisol level is highest when you wake up in the morning and lowest when youre ready for sleep. Children tend to have less cortisol than adults do. Aside from stress, quite a few things can affect your cortisol levels, including:

If your cortisol levels are abnormally high for a long time, it can cause a rare disorder called Cushings syndrome. Treatment for Cushings syndrome may include a cortisol blocker. A rare cause of high cortisol is an ACTH-producing tumor outside the pituitary gland. Adrenal gland problems can also cause high cortisol levels.

According to the Mayo Clinic, overexposure to stress hormones, including cortisol, can cause trouble within almost all your bodys processes, increasing your risk of weight gain, sleep problems, and anxiety.

Inability To Build Muscle

Glucocorticoid Hormone Excess (Cushing’s Syndrome) – Medical Surgical – Endocrine – @Level Up RN

If youve experienced muscle weakness, and a seeming inability to gain strength, cortisol could be the culprit. Studies have shown that cortisol decreases the uptake of amino acids by muscle, inhibiting protein synthesis.5 The end result? There is no construction of new muscle.

As if that wasnt bad enough, cortisol also breaks down muscle, as well as the important connective tissue collagen. Collagen is also an integral component of bone and cartilage. As Savers know, building new muscle is essential, since the stress that muscles place on bone directly stimulates bone formation, per Wolffs Law.

What Tests Are Used To Diagnose Adrenal Adenoma

Your healthcare provider will perform a physical exam and ask you about your symptoms and medical history. They may perform any of the following tests to learn more about your tumor:

  • Blood or urine test:A blood or urine test allows your healthcare provider to check for elevated hormone levels that may be a sign of a functioning tumor. You may need to collect your urine for 24 hours so they can test it for elevated cortisol.
  • Imaging:A CT scan is the most commonly used imaging procedure used to diagnose adrenal adenoma. In some instances, your healthcare provider may order an MRI instead. Imaging helps them determine whether a tumor is malignant or benign. For example, larger tumors are more likely to be cancerous than smaller tumors.
  • Biopsy: Your healthcare provider may perform a fine-needle aspiration if other tests dont provide enough information about whether a tumor is cancer or an adrenal adenoma. During this procedure, theyll use a thin hollow needle to remove tissue from the tumor. A lab specialist, called a pathologist, examines the tissue underneath a microscope to check for signs of cancer.

Other tests may include adrenal vein sampling or a metaiodobenzylguanidine scan.

How To Test Your Cortisol Levels

A blood, saliva, or urine test can be done to measure your cortisol levels. Depending on the cause, your GP might sometimes arrange a cortisol test, most commonly using a blood test.

Cortisol blood test

A cortisol blood test is usually done in the morning when your cortisol levels tend to be at their highest. Cortisol levels tend to fall as the day goes on, reaching their lowest point at night before bed.

Cortisol urine test

A cortisol urine test involves collecting all of your urine over the course of a day. This can help to show how your cortisol levels change throughout the day.

What Does High Cortisol Mean

Cortisol is a hormone mainly secreted inside the human body by adrenal glands. The main function of cortisol is to help the body in responding to stressful conditions. Apart from helping in stressful conditions, cortisol also plays an important role in various body functions. These include immunity modulation, reducing inflammation, maintaining blood sugar levels, regulating metabolism, and improving memory.

The normal level of cortisol depends upon various factors including the time of measurement, age, sex, type of sample, whether blood or urine, and the analytical method used to determine the levels of cortisol.

The value of cortisol changes according to the circadian rhythm. The level of cortisol is highest in the morning and lowest at night. The normal level of cortisol is 10 to 20 mcg/dL between 6:00 am to 8:00 am while the value at 4:00 pm is approximately 3 to 10 mcg/dL.

When the person wakes up with a normal or increased level which does not drop down by evening or when the person goes to bed indicates high cortisol levels. Further tests are done to confirm the cause of the increased level of cortisol.

Urinary Free Cortisol Measurement

Stress response system stock vector. Image of acth, axis

In some centers, testing begins with a 24-hour measurement of urinary free cortisol, which is elevated > 120 mcg/24 hours in almost all patients with Cushing syndrome. However, many patients with elevations of urinary free cortisol between 100 and 150 mcg/24 hours have obesity, depression, or polycystic ovaries but not Cushing syndrome. Normal ranges may vary according to assay.

A patient with suspected Cushing syndrome with grossly elevated urinary free cortisol almost certainly has Cushing syndrome. Two to three normal collections usually exclude the diagnosis. Slightly elevated levels generally necessitate further investigation, as do normal levels when clinical suspicion is high.

A baseline morning serum cortisol measurement should also be done.

How Does It Work

Your hypothalamus and pituitary gland both located in your brain can sense if your blood contains the right level of cortisol. If the level is too low, your brain adjusts the amount of hormones it makes. Your adrenal glands pick up on these signals. Then, they fine-tune the amount of cortisol they release.

Cortisol receptors which are in most cells in your body receive and use the hormone in different ways. Your needs will differ from day to day. For instance, when your body is on high alert, cortisol can alter or shut down functions that get in the way. These might include your digestive or reproductive systems, your immune system, or even your growth processes.

Sometimes, your cortisol levels can get out of whack.
