What Does High Cortisol Levels Mean

Factors Increasing Cortisol Levels

What does Cortisol Do? | 4 Functions of Cortisol Hormone
  • Viral infections increase cortisol levels through activation of the HPA axis by cytokines.
  • Intense or prolonged aerobic exercise transiently increases cortisol levels to increase gluconeogenesis and maintain blood glucose however, cortisol declines to normal levels after eating ” rel=”nofollow”> energy balance)
  • Severe trauma or stressful events can elevate cortisol levels in the blood for prolonged periods.
  • Low-carbohydrate diets cause a short-term increase in resting cortisol , and increase the cortisol response to aerobic exercise in the short- and long-term.

Cortisol is synthesized from cholesterol. Synthesis takes place in the zona fasciculata of the adrenal cortex. While the adrenal cortex also produces aldosterone and some sex hormones , cortisol is its main secretion in humans and several other species. . The medulla of the adrenal gland lies under the cortex, mainly secreting the catecholamines adrenaline and noradrenaline under sympathetic stimulation.

Cortisol is metabolized reversibly to cortisone by the 11-beta hydroxysteroid dehydrogenase system , which consists of two enzymes: 11-beta HSD1 and 11-beta HSD2.

  • 11-beta HSD1 uses the cofactor NADPH to convert biologically inert cortisone to biologically active cortisol
  • 11-beta HSD2 uses the cofactor NAD+ to convert cortisol to cortisone

An alteration in 11-beta HSD2 has been implicated in essential hypertension and is known to lead to the syndrome of apparent mineralocorticoid excess .

Treatment Of Cushings Disease

Microsurgical resection of an ACTH-secreting pituitary adenoma is the optimum treatment for Cushings disease with cure rates of 80-90 percent if a tumor is found. Surgery is most often done through a transnasal transsphenoidal approach, which will not leave a visible scar. This type of surgery may be performed, per the surgeons preference, using either a minimally invasive operating microscope or with the use of an endoscope. Partial removal of the pituitary gland may be used in patients without clearly identifiable adenomas.

In patients to whom a remission is not obtained after surgery, the use of various medications that can inhibit cortisol production may be used, such as:

These agents are not as effective as surgery and are considered a secondline course of treatment. In some patients who are particularly resistant to all forms of therapy, removal of the adrenal glands bilaterally may be considered.

Post-surgery, with successful tumor removal, the production of ACTH drops below normal. This decrease is natural and temporary, and patients are prescribed a synthetic form of cortisol such as hydrocortisone or prednisone to compensate this change. Most patients can discontinue replacement therapy within six to 12 months, but others may require the use of oral steroids for several years to, possibly, their lifetime. Patients who need adrenal surgery may also require steroid replacement therapy.

Get Your Cortisol Rhythm Back On Track

High cortisol levels may not necessarily be a bad thing. Itâs only when cortisol production remains high after the early morning spike that you need to watch out for.

Various factors can cause high cortisol levels. But the biggest culprits on the list are sleep insufficiency, chronic stress, circadian misalignment, high-intensity exercise or overtraining and certain medical conditions like Cushingâs disease.

Before you consult your primary doctor, the RISE app is worth a try to keep your sleep debt low, your stress levels in check, and your body clock aligned.

Risk Factors For Cushings Syndrome

A few inherited endocrine tumor syndromes increase a persons risk for pituitary and adrenal tumors, which can produce cortisol. The most common one is MEN1. Any patient with confirmed macronodular hyperplasia also should be tested. Genetic testing and counseling are recommended for people with more than one hormone-producing tumor. It should also be considered for patients who have multiple family members with these tumors.

Circadian Rhythm And Cortisol


Your sleep-wake cycle follows a circadian rhythm. Every 24 hours, roughly synchronized with nighttime and daytime, your body enters a period of sleep followed by a waking period. The production of cortisol in your body follows a similar circadian rhythm.

Cortisol production drops to its lowest point around midnight. It peaks about an hour after you wake up. For many people, the peak is around 9 a.m.

In addition to the circadian cycle, around 15 to 18 smaller pulses of cortisol are released throughout the day and night. Some of those smaller bursts of cortisol correspond to shifts in your sleep cycles.

Don’t Miss: Foods That Cause Hormonal Imbalance

Enjoy A Healthy Diet To Lower Cortisol Levels

Foods that can increase cortisol are refined sugars, unhealthy carbs, and saturated fats. Healthy food choices such as increasing your intake of fruits and vegetables help balance your hormones better.

The journal Advances in Nutrition reported that a poor diet can affect cortisol concentrations. This can have an impact on cognitive function and affect the HPA axis. Studies have shown that supplements such as magnesium can help to decrease the concentration of cortisol if its elevated.

If you have type 2 diabetes and show signs of excess cortisol, then enjoying a healthy diet is essential to control your symptoms.

As well as eating the right foods to help control cortisol, it is essential to drink plenty of fluids. Researchers have found that your levels of hydration can affect cortisol. When the body is dehydrated, cortisol levels increase.

Why The Test Is Performed

The test is done to check for increased or decreased cortisol production. Cortisol is a glucocorticoid hormone released from the adrenal gland in response to adrenocorticotropic hormone . ACTH is a hormone released from the pituitary gland in the brain.

Cortisol affects many different body systems. It plays a role in:

What Can You Do To Lower Your Cortisol Levels

Cortisol is a hormone that is naturally produced in our bodies. It has been linked to weight gain and fat storage, but in recent years there has been increasing evidence that higher levels of cortisol may have an impact on your mental health. Its been found that people who had higher cortisol levels were more likely to have anxiety and depression than people with lower levels. According to researchers at the University of Michigan, there are a number of factors that can influence your cortisol levels, including sleep, stress, diet, and exercise. Eating a healthy diet that contains plenty of protein can help you to build up a healthy body and avoid obesity. And exercising regularly can help to improve your mood and reduce stress. The researchers suggest that it may also be possible to regulate your cortisol levels by taking supplements that contain specific ingredients, including L-theanine and B-5.

What Do The Results Mean

What is Cortisol? How cortisol levels impact your health

A cortisol test alone can’t diagnose the cause of abnormal cortisol levels. If your cortisol level isn’t normal, you will usually have more tests to find out what is causing the problem.

High levels of cortisol may be a sign that you have Cushing’s syndrome. It may be caused by:

  • Taking high doses of certain steroid medicines for a long time to treat conditions, such as asthma, rheumatoid arthritis, and lupus
  • Tumors in your pituitary gland or other parts of your body that make too much of the hormone that tells your adrenal glands to make cortisol
  • Tumors in your adrenal glands that make extra cortisol

Low levels of cortisol may mean you have Addison disease or secondary adrenal insufficiency:

  • Common causes of Addison’s disease include damage to the adrenal glands from conditions, such as:
  • Certain infections, such as tuberculosis and HIV/AIDS
  • Common causes of secondary adrenal insufficiency include:
  • Autoimmune diseases
  • Traumatic brain injury
  • The most common cause of low cortisol levels is suddenly stopping steroid medicines after using them for a long time.

    If your cortisol results aren’t normal, it doesn’t always mean you have a medical condition that needs treatment. Cortisol levels can be affected by:

    • Certain medicines, such as birth control pills

    How Is The Cortisol Level Test Done

    A blood sample is used to measure cortisol levels. Most blood samples are collected using this process:

    • The flow of blood in the arm is stopped by wrapping an elastic band around your upper arm. This also causes the veins in your arm to become more visible, making it easier to insert the needle.
    • Alcohol is used to clean the site on your skin where the needle will be inserted.
    • The needle is inserted into the vein. This may cause a brief pinching or stinging sensation.
    • Your blood is collected in a tube thats attached to the needle. More than one tube may be needed.
    • The elastic band is removed after enough blood has been collected.
    • As the needle is removed from your skin, cotton or gauze is placed on the site of the needle insertion.
    • Pressure is applied to the area using cotton or gauze. A bandage is used to secure the cotton or gauze.

    At-home cortisol testing kits are also available. You can purchase a test kit online from LetsGetChecked here.

    There are few risks associated with the cortisol level test. The test is done by taking a blood sample from your vein, which may result in some bruising at the site where the needle was inserted.

    In rare cases, the following risks may be associated with having blood drawn from your vein:

    • excessive bleeding
    • an accumulation of blood beneath your skin, which is called a hematoma
    • lightheadedness or fainting

    Cortisol levels are sometimes decreased by:

    • drugs containing androgens

    Higher-than-usual cortisol levels may indicate that:

    Cortisol And Cushing Syndrome

    An excess of cortisol in the blood may cause Cushing Syndrome. Cortisone drugs are active in the development of this syndrome. Since tumors in any part of the body can increase the production of cortisol, they may cause Cushings syndrome. The most common symptoms are weight gain, hypertension, memory problems, loss of attention and concentration.

    Cushings syndrome can lead to osteoporosis, muscle weakness, increased thirst, frequent urination, bruises and cracks in the skin, facial rash and sexual reluctance.

    Effects Of Chronically High Cortisol

    Cortisol and Diabetes: Is there a Hormonal Connection?

    If cortisol elevation becomes chronic, it leads to more than feeling burned out. You could be at higher risk for developing a condition called Cushings diseasewhich can include excessive weight gain, weakness, high blood pressure, and the tendency to bruise easily.

    And it doesnt stop there. Mayo Clinic notes that high cortisol can affect multiple systems in your body, from brain function to gut health, putting you at increased risk for:

    • Heart disease and heart attack

    • High blood pressure

    Dr. Messer adds that other issues related to chronically high cortisol levels are , , and .

    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.

    Fight Or Flight Response

    Some physical effects of cortisol related to the fight or flight response include:

    • Triggering a release of glucose to supply immediate energy to your large muscles.

    • Inhibiting production and digestion so glucose will be available and not stored.

    • Narrowing the arteries so blood pumps harder and faster to the heart and large muscles.

    Inability To Build Muscle

    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.

    How Does Cortisol Affect Female Hormones

    How To LOWER Cortisol Levels? â Dr. Berg

    Aside from affecting the menstrual cycle, abnormal levels of CRH in reproductive tissue have been associated with negative pregnancy outcomes, such as preterm birth. .

    Cortisol actually increases the cravings for sweets.

    High cortisol lowers oestrogen levels, which can result in the deposition of fat, often in the middle section of the body. When oestrogen is lowered from continuous stress and cortisol production, all the female hormone imbalance symptoms such as night sweats, sleep problems, and mood swings can get worse.

    If not managed, high cortisol can cause many other important hormones to become out of balance.

    Will I Need To Do Anything To Prepare For The Test

    The preparations will depend on the type of test you are having. Be sure to follow all the instructions that your provider gives you.

    Stress can raise your cortisol levels, so you may need to rest before your test. A blood test will require you to schedule two appointments at different times of the day. Before a saliva test, you may need to stop using certain medicines. Let your provider know about all medicines you use, including skin creams. But don’t stop using any medicines without talking with your provider first.

    What Is An Adrenocorticotropic Hormone Test

    This test measures the level of adrenocorticotropic hormone in the blood. ACTH is a hormone made by the pituitary gland, a small gland at the base of the brain. ACTH controls the production of another hormone called cortisol. Cortisol is made by the adrenal glands, two small glands located above the kidneys. Cortisol plays an important role in helping you to:

    • Regulate metabolism, the process of how your body uses food and energy

    Too much or too little cortisol can cause serious health problems.

    Causes Of Cortisol Deficiency

    Cortisol deficiency occurs when the adrenal glands do not produce enough cortisol. Main reasons:

    • Pituitary gland damaged by tumor or head trauma
    • Disfunction of the adrenal glands
    • Loss of function or surgical removal of adrenal glands

    Other diseases such as excessive blood loss, tuberculosis, AIDS, congenital adrenal hyperplasia can also lead to cortisol deficiency.

    Got stress? Who doesnt these daysand its no surprise that an overabundance of stress, particularly when its chronically elevated, can on your body and emotions. Still, some stress isnt necessarily a bad thing: Elevated levels of anxiety trigger the release of hormones related to the stress response, and one of those hormones, called cortisol, plays an important role in daily functioning, helping us awake refreshed, be more focused, and maintain energy throughout the day.

    The key? Regulating those cortisol levels. Because when cortisol is too high, and especially if it feels stuck in that position as it can with Cushing’s disease or Cushing’s syndrome, there can be some serious and negative health effects as a result.

    Weve all felt that surge of energy as we confront something threatening or startling. A barely avoided car accident. A call that your child has been hurt. The pressure to meet a deadline.

    As your body perceives stress, your adrenal glands make and release the hormone cortisol into your bloodstream. Often called the stress hormone, cortisol causes an increase in your heart rate and blood pressure. Its your natural flight or fight response that has kept humans alive for thousands of years.

    Normal levels of cortisol also are released when you wake up in the morning or exercise. These levels can help regulate your blood pressure and blood sugar levels and even strengthen your heart muscle. In small doses, the hormone can heighten memory, increase your immune system and lower sensitivity to pain.

    If your body experiences chronic stress, you may begin to feel unpleasant and even dangerous effects, such as:

    • Muscle pain or tension in the head, neck, jaw, or back
