Learning About Cortisol

What is Cortisol?

I find myself bombarded everywhere about this one word and even as Karen G Clemenson came home and asked me about it, I knew we needed to be learning about cortisol. Cortisol is a hormone that helps control our mood, motivation, and fear. Cortisol does this by helping our body regulate how our body uses glucose (sugar), manages inflammation, regulates blood pressure, and controls our sleep-wake cycle or circadian rhythm. Our hypothalamus and pituitary gland, both located in our brain, controls our cortisol production by releasing other hormones. In order to have healthy cortisol production our hypothalamus, pituitary gland and adrenal glands must all be working correctly. Cortisol regulates many functions and affects almost all organ systems in our body.

Cortisol manages how our body uses carbohydrates, fats and proteins. When we experience stress, our bodies release adrenaline and cortisol to keep us on alert. When cortisol is released, this triggers the release of glucose from our liver so we have energy and a burst of higher immunity. Cortisol also tells our pancreas to decrease insulin and increase glucagon in order to regulate blood sugar. In a body with normal short spurts of stress, cortisol can limit inflammation. However if our body becomes used to regular high levels of stress so that it becomes used to a traumatic life, we can have chronic inflammation and a weakened immune system.

People with high levels of cortisol can have high blood pressure. They can also suffer with anxiety, depression, headaches, and heart disease. People with lower than normal levels of cortisol can have low blood pressure.

Symptoms of High Cortisol Levels

Symptoms of high cortisol levels, or people who may may have Cushing syndrome, which is caused by a mass in your adrenal gland or a tumor in your pituitary gland can include:

Easy bruising
Excessive hair growth in females
Fatty deposit at the base of the neck between shoulder blades
High blood pressure
High blood sugar, which often turns into Type 2 diabetes
Muscle weakness in your upper arms and thighs
Purple streaks on the breasts, hips, stomach and under the arms
Thin arms and legs
Weak bones (osteoporosis) and bone breaks
Weight gain, especially in face and belly

What Causes High Cortisol?

It is normal to have times of stress in our lives. Cortisol levels will usually return to normal after times of stress are over. Sometimes cortisol levels can remain high and you might require help from a professional if you continuously suffer with the following:

Chronic physical, mental or psychological stress
Cushing’s syndrome
Long-term steroid use
Sleep deprivation and abnormal sleep patterns
Tumors or growths on the adrenal glands or pituitary glands

Low Cortisol

Too little cortisol can be caused by several factors including:

Autoimmune disorders
Congenital adrenal hyperplasia, which is a group of inherited disorders that decrease adrenal gland function
Hypoglycemia
Infections like tuberculosis and HIV can impact the adrenal glands
Primary adrenal insufficiency, referred to as Addison’s disease, happens when your immune system attacks your adrenal glands
Secondary adrenal insufficiency or hypopituitarism, takes place when you have a tumor on your pituitary gland or an underactive pituitary gland
Suddenly stopping steroid, otherwise called, corticosteroid medications, after taking them for a long time
Traumatic brain injury can challenge pituitary gland, which regulates the adrenals

Symptoms of Low Cortisol Levels:

Abdominal pain
Diarrhea, nausea, and vomiting
Fatigue
Hyperpigmentation, or dark patches of skin
Hypoglycemia, low blood sugar
Muscle weakness that grows worse
Loss of appetite
Low blood pressure, hypotension
Unintentional weight loss

What You Can Do to Reduce High Cortisol Levels:

Although some medical conditions require medical treatment there are ways you can change your lifestyle to help your body naturally lower your cortisol levels:

Avoid stress
Build and maintain healthy relationships
Create a healthy sleep schedule
Eat a nutrient rich diet
Enjoy yourself and laugh
Guided Imagery
Journaling
Listening to music
Meditation
Move your body daily
Practice deep breathing exercises
Reframe negative thoughts
Restrict social media use
Self-hypnosis
Sex
Yoga

Social media has been connected to stress because it has been found that social media impacts our neuroendocrine system, which tends to be associated with the part of our brain that handles our bad habits or things we misuse or overuse. In a study it showed that 20 minutes of social media use generated a higher cortisol level for depressed adolescents, than nondepressed adolescents. Those likes actually produce dopamine hits; another hormone that makes us feel good.

What is Normal?

Taking a cortisol test can tell your medical team if your cortisol levels are correct or if they need to be managed. Normal cortisol levels range from 5-25 micrograms per deciliter (mcg/dL) around 8 am. Cortisol levels change throughout the day, the morning being the highest level, and the evening being the lowest level. The test can require blood (taken by a medical professional), urine or saliva which can be done at home. Samples will be taken at different times during a 24 hour period.

What is normal is hard to define for many reason, some reasons being, are even how we respond to stressors. Some of us are just better able to handle stress than others. While some of us, secrete more cortisol than others, in the same situation. For people with chronic stress, they might need to incorporate many tools into their daily life to manage their cortisol levels.

When to Contact A Medical Professional

Please seek medical attention if you are experiencing the following:

Abdominal pain
Dizziness or lightheadedness
High or Low blood pressure
Reduced consciousness
Severe depression and thoughts of ending your life
Trouble breathing
