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.
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.
Released To Handle Stress Cortisol Is An Important Hormone But When Levels Get Too High It Can Be Tough On Your Body
by Health Writer
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.

Cortisol And Metabolism: What To Know
Cortisol, specifically, plays a role in metabolism. It stimulates the liver to increase the production of blood sugar. It also helps the body convert fats, proteins, and carbohydrates into usable energy. As part of the bodys fight-or-flight response, cortisol is released during stressful times to give your body a natural energy boost. This boost is meant to fuel your muscles to respond to a threatening situation. But when cortisol levels are constantly high due to chronic stress, these same effects may result in hyperglycemia and, in turn, type 2 diabetes.
Cortisol also helps the body fight inflammation and regulate blood pressure.
This hormone is produced by the adrenal glands, two small, triangular-shaped glands that sit on top of each kidney. From the adrenal glands, cortisol can be released directly into the bloodstream.
The pituitary gland and hypothalamus can sense whether the blood has the right amount of cortisol in it. These two brain regions work together to direct the adrenal glands to produce more or less cortisol, in essence acting as the control mechanism regarding how much cortisol is made.
This connection between the hypothalamus, pituitary gland, and adrenal glands forms the backbone of the bodys stress response system.
The Autonomic Nervous System
The autonomic nervous system is part of your body’s nervous system and is made up of:
- The sympathetic nervous system , also known as the fight-or-flight response
- The parasympathetic nervous system , commonly known as the rest-and-digest or feed-and-breed response
The ANS works in tandem with the HPA axis to react to external stressors. But, what exactly is the HPA axis?

Should I See A Doctor
If you think you might have high cortisol, its important to see a doctor for a blood test. High cortisol causes common signs and symptoms that can be caused by many other diseases, so its important to confirm whats causing your symptoms.
If youre experiencing symptoms that may be caused by high cortisol levels, your doctor may recommend the following tests:
- Cortisol urine and blood tests. These tests measure the levels of cortisol in your blood and urine. The blood test uses a sample of blood drawn from your vein. A test called the 24-hours urinary free cortisol excretion test is used to check your urine. This entails collecting urine over a 24-hour period. Blood and urine samples are then analyzed in a laboratory for cortisol levels.
- Cortisol saliva test. This test is used to check for Cushing syndrome. A sample of saliva collected at night is analyzed to see if your cortisol levels are high. Cortisol levels rise and fall throughout the day and drop significantly at night in people without Cushing syndrome. High cortisol levels at night would indicate you may have Cushing syndrome.
- Imaging tests. CT scans or an MRI may be used to obtain images of your pituitary gland and adrenal glands to check for tumors or other abnormalities.
Unmanaged high cortisol levels can have serious consequences on your health. Left untreated, high cortisol can your risk of serious health conditions, including:
- cardiovascular disease

High Levels Of Cortisol And Cushings Syndrome
Cushings syndrome is characterised by high levels of the hormone cortisol. Another name for Cushings syndrome is hypercortisolism. Some people develop Cushings syndrome symptoms when they take high levels of oral corticosteroid medication to treat inflammatory conditions such as asthma, lupus or rheumatoid arthritis. Other causes include tumours of the pituitary and adrenal glands, and tumours in other areas of the body. In these cases the body itself is producing too much cortisol.Symptoms of Cushing’s syndrome may include:
- weight gain in the face, abdomen and chest
- wasting of the limbs
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.

What Causes High Levels Of Cortisol
Experiencing abnormally high levels of cortisol for an extended period of time is usually considered Cushings syndrome, which is a rare condition. Causes of higher-than-normal cortisol levels and Cushings syndrome include:
- Taking large amounts of corticosteroid medications, such as prednisone, prednisolone or dexamethasone, for treatment of other conditions.
- Tumors that produce adrenocorticotropic hormone . These are usually found in your pituitary gland. More rarely, neuroendocrine tumors in other parts of your body such as your lungs can cause high cortisol levels.
- Adrenal gland tumors or excessive growth of adrenal tissue , which cause excess production of cortisol.
What are the symptoms of high cortisol levels?
The symptoms of Cushings syndrome depend on how elevated your cortisol levels are. Common signs and symptoms of higher-than-normal cortisol levels include:
- Weight gain, especially in your face and abdomen.
- Fatty deposits between your shoulder blades.
- Wide, purple stretch marks on your abdomen .
- Muscle weakness in your upper arms and thighs.
- High blood sugar, which often turns into Type 2 diabetes.
- Weak bones and fractures.
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.

Cushings Syndrome And Cortisol: What To Know
Cushings syndrome happens when there is too much cortisol in the blood for a prolonged period of time. This can cause physical and mental changes.
Cushings syndrome symptoms may include:
- Skin that bruises easily
- Problems thinking clearly
The most common cause of Cushings syndrome is taking steroid-type drugs, such as prednisone , which are structurally very similar to cortisol. This type of Cushings syndrome typically goes away after medication is stopped, but you need to talk to your doctor before stopping a medication like prednisone.
Cushings syndrome also can be caused by a small tumor on the pituitary gland.

What Do The Results Mean
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
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
