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.
Why Are Your Cortisol Levels So High
The HPA axis is the part of the endocrine system that helps you deal with stress. Cortisol is a hormone released by the adrenal glands when you are stressed. Cortisol is a very important hormone as it is needed to fight or flight in the event that you are stressed. Too much cortisol can lead to weight gain and diabetes, so it is important to monitor the levels of cortisol and keep it at a healthy level. Cortisol levels are linked to obesity, and high cortisol levels are often a result of stress. Cortisol can be measured through saliva tests. The pros and cons of the saliva test are that the test is very easy to perform and the test is fast, but it is also not accurate. Additionally, it is important to keep in mind that cortisol levels can vary from day to day.
How To Lower Cortisol Levels Through Medication
Medication is only used if cortisol is needed permanently that is, over a lifetime and no other form of treatment can help like, for example, in people with Addisons disease or Cushings disease. For a long time, the drugs metyrapone, aminoglutehimide, mifepriston, and ketoconazole have been used. They lower cortisol levels by inhibiting the enzyme needed for the synthesis of steroids.

Moderate Exercise To Lower Cortisol
Enjoying regular exercise can help to reduce your cortisol levels because it helps to cope with stress better.
The Journal of Endocrinological Investigation reported that moderate, low-intensity exercise has a positive effect on cortisol levels. However, intensive exercise increases cortisol secretion in the body.
Interestingly, sweating after exercise can cause high concentrations of cortisol in the body and these concentrations are detected in hair. Doctors can test hair samples for cortisol to help diagnose conditions related to chronic stress.
Walking is a great low impact exercise that can act as a cortisol reducer and manage your stress levels. One of the benefits of walking every day is that it helps to get rid of excess body fat.
How Can I Reduce My Cortisol Levels
If you have Cushings syndrome youll need medical treatment to lower your cortisol levels. Treatment usually involves medication and/or surgery. Youll also need medical treatment if you have lower-than-normal cortisol levels.
In general, though, there are several everyday things you can do to try to lower your cortisol levels and keep them at optimal ranges, including:

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.
How Does Cortisol Affect Female Hormones
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.

Is Cortisol A Stress Hormone
Cortisol is widely known as the stress hormone. However, it has many important effects and functions throughout your body aside from regulating your bodys stress response.
Its also important to remember that, biologically speaking, there are multiple different kinds of stress, including:
- Acute stress: Acute stress happens when youre in sudden danger within a short period of time. For example, barely avoiding a car accident or being chased by an animal are situations that cause acute stress.
- Chronic stress: Chronic stress happens when you experience ongoing situations that cause frustration or anxiety. For example, having a difficult or frustrating job or having a chronic illness can cause chronic stress.
- Traumatic stress: Traumatic stress happens when you experience a life-threatening event that induces fear and a feeling of helplessness. For example, experiencing an extreme weather event, such as a tornado, or experiencing war or sexual assault can cause traumatic stress. In some cases, these events can lead to post-traumatic stress disorder .
Your body releases cortisol when you experience any of these types of stress.
Treatment Of Cushing’s Syndrome
Treatment of Cushings syndrome depends on the underlying cause of excess cortisol but may perhaps include surgery, radiation, chemotherapy or the use of cortisol-inhibiting drugs. If the cause is iatrogenic, from long-term use of glucocorticoid hormones to treat another disorder, the physician will gradually reduce the dose of the externally administered steroid to the lowest dose adequate for control of that disorder. Once control is established, the dose of glucocorticoid hormones may be given on alternate days to lessen side effects for the patient.

How To Fix High Or Low Cortisol
Resting is the best way to correct high or low cortisol.
“It’s not super sexy,” Azzaro says, “but your body is telling you to rest. The dirty work of correcting a cortisol imbalance is to identify what the root cause of the imbalance is and then correct that to bring cortisol back into balance.”
We discussed general causes of cortisol imbalance above, but dig deeper. Go past “diet” or “exercise” and ask yourself if your hormone levels are wacky because of:
- Relationship stress
- Hustle culture/doing too much

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

Can Stress Cause Stomach Pain
Symptoms in the digestive tract, such as stomach pain, constipation, and diarrhea, are particularly typical of stress. The fact that the psyche can affect the stomach probably comes as little surprise to you. You have probably experienced for yourself the sensation of butterflies in your stomach when you are nervous or anxious about exams or have stage fright.
In fact, there is a close connection between the psyche and the digestive tract that is, the gut. It is not for nothing that we speak of the gut as the bodys second brain. Among other things, the intestines and the brain constantly communicate with each other via the vagus nerve, one of the largest nerves in the body. For example, your digestive tract can let you know when you have eaten something bad. The brain reacts by giving you nausea and a nausea stimulus to get rid of the toxins.
In recent years, it has become increasingly clear what role the gut flora or gut microbiome plays in this. The trillions of bacteria in the gut are involved in communication with the brain. Some studies have shown that chronic stress can influence the composition of the gut flora and possibly disrupt the balance between good gut bacteria such as the lactobacilli and bifidobacteria and bad bacteria.
Did you know that if you add up all the trillions of tiny organisms in your gut, they weigh about as much as your brain?
When Should I Test My Cortisol Levels
You should test cortisol levels if you have symptoms of either low or high cortisol. High levels can affect your heart rate and energy levels.
Symptoms of Addisonâs disease include extreme fatigue, weight loss, darkening of the skin, low blood pressure , and more³. Levels of ACTH, the hormone that stimulates the production of cortisol, can be either elevated or decreased, depending on the cause of low cortisolâ´. Other tests may be needed to diagnose this disease.
Symptoms of Cushing syndrome include obesity, high blood pressure, and elevated blood glucose levelsâ´.

How Do Doctors Treat Cushings Syndrome
Treatment depends on the cause and may include surgery, radiation, chemotherapy, or cortisol-reducing medicines. If the cause is long-term use of glucocorticoids to treat another disorder, your doctor will gradually reduce your dosage to the lowest dose that will control that disorder. Sometimes disorders that doctors treat with glucocorticoids can be treated with a non-glucocorticoid medicine instead.
What Is A Cortisol Test
A cortisol test measures the level of cortisol in your body. Cortisol is a hormone made by your adrenal glands. The test determines whether you have too much or too little of the hormone.
The test requires a sample of blood, urine, saliva or a combination. The results can help healthcare providers diagnose:
- Addisons disease, also known as hypocortisolism or primary adrenal insufficiency. This condition happens when your body has too little cortisol.
- Cushings syndrome, also called hypercortisolism. The condition occurs when your body has too much cortisol.
- Tumor affecting the production of cortisol. Various tumors may cause high cortisol levels.
A cortisol test is sometimes called:
- Urinary cortisol.

What Are Typical Signs Of Stress
Commonly observed high cortisol symptoms include:
- Stomach pain, diarrhea, and other digestive problems
- Skin rash and other skin problems for example, acne
- Headaches and back, neck, and joint pain
- Palpitations and dizziness
- Tiredness, fatigue, and sleep problems
In addition to these relatively immediate symptoms, there are also long-term consequences that chronic stress can trigger. The best-researched are the connections with the cardiovascular system stress has an effect on blood pressure and pulse rate, among other things, and many studies confirm that there is an obvious connection.
Other possible long-term consequences of long-term stress are:
- Mental illnesses such as depression, burnout, anxiety disorders
- Poor concentration and chronic fatigue
- Obesity and diabetes
- Susceptibility to infection
Besides some evidence that suggests stress is related to ringing in the ears and tinnitus, other studies additionally found that people who experience chronic stress are likely to have more upper respiratory infections, such as flu or colds. Researchers therefore suspect that stress can weaken the immune system in the long run.
In women, high cortisol levels can also lead to thicker or more visible body and facial hair , irregular or absent menstrual periods and in men to impotence and loss of libido and fertility.
What Are The Symptoms Of High Cortisol Levels
Regular and prolonged exposure to high cortisol levels can wreak havoc on your body. Over time this can cause Cushings syndrome. Some of the most common signs of high cortisol levels include:
- weight gain particularly around your stomach, upper back, and face
- bruising and slow wound healing
- difficulty concentrating
Over time, high cortisol can put you at risk of heart disease, osteoporosis, diabetes, and poor mental health.

How Does A Cortisol Test Work
Cortisol can be measured in the blood, urine, saliva or a combination. Your healthcare provider will tell you which test they recommend for you.
- Blood test: In an office, clinic or lab, a healthcare provider inserts a thin needle into a vein in your arm. The needle collects a small sample of blood into a tube. You might feel a slight sting when the needle goes in.
- Saliva test: You or a healthcare provider puts a swab in your mouth and waits a few minutes until the swab is saturated with spit. If you do the test yourself at home, your healthcare provider will give you a special kit. Theyll tell you what time to perform the test and how to return the sample.
- Urine test: Your healthcare provider gives you a container to collect your pee. Most urinary cortisol tests collect all the pee you produce in 24 hours. Your healthcare provider may ask you to store the urine in a cold place, then return it to their office or a lab.
You may need to repeat cortisol testing twice in one day or multiple times over several days because cortisol levels vary.
Is There Any Truth To Cortisol Blocker Claims
Finding the Truth
Cortisol blockers help decrease your cortisol level. Cortisol is a hormone, sometimes called the stress hormone. Its main job is to help your body function well in times of stress.
Cortisol blockers can be effective in treating high cortisol level disorders, such as Cushings syndrome. However, theyre also marketed as a dietary supplement that can help you curb your appetite, lose weight, and build muscle.
To examine whether or not theres any truth to those claims, it helps to know what cortisol is and what role it plays in your health.

Treatment depends on what’s causing it.
If it’s caused by taking steroids:
- your steroid dose will be gradually reduced or stopped
If it’s caused by a tumour, treatment may include:
- surgery to remove the tumour
- radiotherapy to destroy the tumour
- medicines to reduce the effect of cortisol on your body
Speak to your doctor about the benefits and risks of the different treatment options.
You’re Not Sleeping Well

How Is A Cortisol Level Found
In order to measure cortisol level in the body, a blood sample is taken and analyzed. This is done by wrapping an elastic band usually in the upper arm in order to stop the flow of blood and makes the veins more prominent and easily seen. The site is then cleaned with alcohol swabs and a needle is inserted in the vein and the amount of blood required to analyze the cortisol levels is taken out. This blood is then collected and sent to pathology for analysis of the cortisol levels.
Other Effects Of Cortisol
Some physical effects of cortisol unrelated to fight or flight include:
-
Controlling salt and water balance.
-
Acting as an anti-inflammatory.
-
Helping you wake up in the morning.
-
Regulating immune system function.
-
Regulating growth.
Cortisol release is controlled by a feedback system between your brains hypothalamus gland, the , and the adrenal gland, which together constitute the HPA axis . The hypothalamus and pituitary glands are responsible for ensuring that your blood contains the correct level of cortisol. If its too low or too high, the brain sends signals to the adrenal glands to make more or less.
Once a perceived threat has passed, your cortisol levels should return to normal, causing your heart rate and blood pressure to regulate and your digestion and other body systems to restart. However, in our stress-laden, fast-paced culture, cortisol can remain chronically high. This can cause a variety of health problems, as we discuss below.
