What is Cortisol?

Cortisol is a vital hormone, often called the “stress hormone,” because it plays a vital role in managing how your body responds to stress. It’s produced by your adrenal glands, located just above your kidneys. 

Cortisol doesn’t just help with stress; it’s essential for various functions, such as regulating metabolism, reducing inflammation, and controlling blood pressure. 

This article will explain cortisol and its importance and explore how it affects overall health.

What Is Cortisol?

Cortisol is a steroid hormone that your body naturally produces in the adrenal glands, which sit on top of your kidneys. This hormone plays a key role in your body, influencing how you metabolize food, respond to stress, and maintain your immune system, among other functions. 

The process of making cortisol begins in the brain. When you experience stress, your brain signals your adrenal glands to release cortisol into your bloodstream. This process is part of your body’s way of managing stress by temporarily increasing energy production at the expense of processes that are not essential in an emergency.

The Functions of Cortisol

Cortisol has several important functions in the body. Here are some of the key roles it plays:

Stress Response

Cortisol helps your body handle stress by providing the energy it needs in challenging situations. When stressed, cortisol increases sugars (glucose) in the bloodstream, enhancing your brain’s use of glucose and increasing the availability of substances that repair tissues.

Metabolism Regulation

Cortisol is vital for metabolism, the process that fuels your body by breaking down fats, proteins, and carbohydrates. It helps maintain blood sugar levels and helps your body use it effectively.

Anti-inflammatory Effects

Cortisol helps to reduce inflammation in the body. It controls the swelling and redness that can occur with injuries and can help prevent the immune system from overreacting.

Immune System Interaction

While cortisol is necessary for reducing inflammation, it can also suppress the immune system when levels are too high, which is why chronic stress can weaken it.

Blood Pressure Regulation

Cortisol also helps to regulate blood pressure by controlling the narrowing and widening of blood vessels throughout the body during stressful times.

These functions illustrate how crucial cortisol is to maintaining health and well-being. It allows the body to manage and adapt to stress, regulate critical bodily processes, and maintain balance.

How the Body Regulates of Cortisol

what is cortisol

The body controls how much cortisol is released using a complex system known as the Hypothalamic-Pituitary-Adrenal (HPA) axis. This system involves three parts: the hypothalamus and pituitary glands, located in the brain, and the adrenal glands above the kidneys.

Here’s how it works:

The Hypothalamus Sends a Signal

When your brain detects that you are stressed, the hypothalamus releases a hormone that signals the pituitary gland.

The Pituitary Gland Responds

In reaction to the hypothalamus, the pituitary gland releases another hormone. This hormone travels through your bloodstream to the adrenal glands.

On receiving the signal, the adrenal glands release cortisol into your bloodstream.

Cortisol levels in your body also follow a daily rhythm, peaking in the morning to help you wake up and gradually falling throughout the day to prepare your body for rest at night. 

This daily cycle is why you might feel alert in the morning and tired at night. Understanding and managing stress and maintaining a regular sleep schedule can help stabilize your cortisol levels.

Effects of Abnormal Cortisol Levels

Abnormal cortisol levels can lead to various health issues, depending on whether these levels are too high or too low. Here’s what can happen in each case:

High Cortisol Levels

High cortisol can result from prolonged stress, medical conditions like Cushing’s syndrome, or the use of certain medications.

Symptoms of high cortisol include weight gain, particularly around the belly and face, high blood pressure, mood swings, and even muscle weakness.

Over time, high cortisol levels can increase the risk of heart disease, affect mental health, and lead to poor sleep.

Low Cortisol Levels

Low cortisol levels can be caused by Addison’s disease. This is when the adrenal glands don’t produce enough hormones or damage the adrenal or pituitary gland. Certain medications can also reduce cortisol production.

Common symptoms of low cortisol are fatigue, dizziness, weight loss, and muscle weakness.

If not managed, low cortisol levels can lead to an Addisonian crisis, a potentially life-threatening condition where your body’s response to stress is insufficient.

Both high and low cortisol levels require medical attention to manage properly and to avoid long-term complications. If you experience symptoms of abnormal cortisol levels, consulting with a healthcare provider is essential for proper diagnosis and treatment.

Diagnosing and Managing Cortisol Levels

Diagnosing abnormal cortisol levels typically involves several types of tests. Here are the most common diagnostic methods:

Blood Test: A blood test can measure the amount of cortisol in your blood. This test is often performed in the morning when cortisol levels are at their highest.

Saliva Test: Cortisol levels can also be checked through a saliva test, usually taken at night when cortisol levels should be low.

Urine Test: A 24-hour urine test involves collecting all urine produced in a 24-hour period and can help assess how much cortisol your body is producing over a full day.

If your tests show that your cortisol levels are not normal, your doctor might suggest several treatment options based on the underlying cause:

Medical Treatments

For high cortisol levels due to conditions like Cushing’s syndrome, treatment may involve medications that reduce cortisol production or surgery to remove the source of excess hormone (such as a tumor in the adrenal gland).

Low cortisol levels, as seen in Addison’s disease, may require hormone replacement therapy to maintain normal levels.

Lifestyle Changes

  • Techniques such as mindfulness, meditation, or therapy can help manage stress and thus lower cortisol levels.
  • Eating a balanced diet and avoiding high-sugar and high-fat foods can help regulate cortisol levels.
  • Maintaining a regular sleep pattern can help stabilize your body’s natural rhythms and cortisol production.

Effective management of cortisol levels involves a combination of medical interventions and lifestyle adjustments. Always work with healthcare providers to find the best approach for your specific situation.

It also keeps inflammation down, regulates blood pressure, increases blood sugar, and controls your sleep/wake cycle. Importantly, cortisol assists in managing your body’s response to stress.

What are high cortisol symptoms?

High levels of cortisol can lead to a range of symptoms. Some common signs include:

  • Weight gain, particularly around the abdomen and face
  • A rounded face

  • Mood swings, anxiety, and depression
  • Muscle weakness
  • Increased thirst and frequency of urination
  • Difficulty sleeping or insomnia

What is the function of cortisol?

Cortisol has several critical functions in the body:

  • It boosts energy by increasing glucose in the bloodstream during times of stress.

  • It regulates various bodily functions, including metabolism, inflammation, and immune response.
  • It helps maintain heart and blood vessel function and regulates blood pressure.

What happens when cortisol levels are low?

Low cortisol levels, a condition often associated with Addison’s disease, can cause various symptoms, including:

  • Fatigue and decreased energy
