What Does Too Much Cortisol Do

Overview of Cortisol

Cortisol, also known as the stress hormone, is a vital hormone produced in the adrenal glands. It plays a crucial role in numerous bodily functions and helps regulate various processes in the body. Understanding the definition and function of cortisol is essential to comprehend the potential consequences of excess cortisol.

Definition of cortisol

Cortisol is a steroid hormone released by the adrenal glands in response to stress. It belongs to the glucocorticoid class of hormones and is often referred to as the “stress hormone” due to its association with the body’s stress response. Cortisol levels fluctuate throughout the day, with the highest levels typically in the morning and the lowest during the evening.

Function of cortisol in the body

Cortisol serves several important functions in the body. It helps regulate metabolism, aids in the proper functioning of the immune system, and plays a role in managing stress. Additionally, cortisol helps maintain blood pressure, regulate blood sugar levels, and promote the metabolism of fats, proteins, and carbohydrates. While cortisol is necessary for survival, excessive levels can have detrimental effects on both physical and mental health.

Causes of Excess Cortisol

Excess cortisol can arise from various factors, including chronic stress, certain medical conditions such as Cushing’s syndrome, and the use of specific medications. Understanding these causes is crucial to address and manage cortisol levels effectively.

Chronic stress

Chronic stress can be one of the primary drivers of excess cortisol production. When faced with ongoing stress, whether it be due to work, personal life, or environmental factors, the body continues to release cortisol in response. Prolonged exposure to elevated cortisol levels can have cascading effects on overall health and well-being.

Cushing’s syndrome

Cushing’s syndrome is a rare hormonal disorder caused by prolonged exposure to high levels of cortisol in the body. This condition can either be due to excessive cortisol production by the adrenal glands or the use of corticosteroid medications. Individuals with Cushing’s syndrome often experience a range of symptoms related to excess cortisol.

Certain medications

Certain medications, such as corticosteroids prescribed for inflammatory conditions like asthma or autoimmune disorders, can also increase cortisol levels. While these medications are often necessary and beneficial for managing specific health conditions, they can lead to a temporary elevation in cortisol levels.

Effects on Physical Health

Excess cortisol can impact various aspects of physical health, leading to potential complications and discomfort. Understanding the effects on physical health can help individuals recognize and address any underlying issues related to cortisol levels.

Weight gain and obesity

One of the common effects of excess cortisol is weight gain, particularly in the abdominal area. Cortisol can stimulate the appetite, leading to overeating, especially of unhealthy, high-calorie foods. Additionally, cortisol promotes the storage of fat, particularly around the waistline. This combination can contribute to the development of obesity and its associated health risks.

Weakening of the immune system

Cortisol plays a complex role in immune function, and excess cortisol can impair immune system functioning. Increased cortisol levels can suppress immune responses, making individuals more susceptible to infections, slower wound healing, and a higher risk of developing autoimmune conditions.

Increased blood pressure

Elevated cortisol levels can also contribute to increased blood pressure. Cortisol promotes the narrowing of blood vessels and the redistribution of blood flow, which in turn raises blood pressure. Over time, consistently high blood pressure can lead to cardiovascular complications such as heart disease and stroke.

Elevated blood sugar levels

Cortisol influences the metabolism of glucose, causing an increase in blood sugar levels. This rise in blood sugar can be especially problematic for individuals with diabetes or those at risk of developing the condition. Excessive cortisol can disrupt insulin sensitivity and further complicate blood sugar regulation.

Digestive problems

Excess cortisol can disrupt the digestive system, leading to various gastrointestinal issues. Common problems include stomach ulcers, acid reflux, and an increased risk of developing irritable bowel syndrome (IBS). These disruptions in gut health can cause discomfort, pain, and long-term digestive difficulties if not addressed.

Effects on Mental Health

The impact of excess cortisol is not limited to physical health but extends to mental well-being as well. Understanding how cortisol affects mental health can shed light on the potential consequences of chronically elevated cortisol levels.

Anxiety and depression

Excessive cortisol levels can contribute to the development or worsening of anxiety and depression symptoms. Cortisol can disrupt neurotransmitter balance in the brain, leading to mood disturbances and an increased risk of mental health conditions.

Mood swings

Fluctuations in cortisol levels can lead to mood swings and emotional instability. Individuals with elevated cortisol may experience irritability, anger, and an overall sense of emotional vulnerability. These mood swings can significantly impact day-to-day well-being and interpersonal relationships.

Impaired memory and concentration

High cortisol levels can impair cognitive function, affecting memory, concentration, and overall mental clarity. Individuals may experience difficulty retaining information, problems with focus and attention, and a general feeling of mental fog. These cognitive impairments can significantly impact daily tasks, work performance, and overall quality of life.

Impact on Sleep

Excess cortisol can have a profound impact on sleep patterns and quality, further complicating overall health and well-being. Understanding these effects can facilitate the implementation of strategies to promote better sleep.


Elevated cortisol levels can disrupt the body’s natural sleep-wake cycle, leading to insomnia. Insomnia is characterized by difficulty falling asleep, staying asleep, or experiencing non-restorative sleep. The ongoing cycle of stress and disrupted sleep can further exacerbate cortisol levels, creating a vicious cycle that is challenging to break.

Poor quality of sleep

Even in individuals who manage to sleep, excess cortisol can disrupt the quality of sleep. Cortisol can interfere with the normal progression of sleep stages, leading to lighter and less restorative sleep. Consequently, individuals may wake up feeling tired and unrested, with impaired cognitive function and reduced productivity during the day.

Bone Health

Excessive cortisol levels can have long-term consequences for bone health, increasing the risk of osteoporosis and fractures. Understanding these effects is crucial, especially for individuals at higher risk or with pre-existing bone conditions.


Elevated cortisol levels can interfere with bone remodeling and calcium absorption, leading to a loss of bone density. Over time, this can increase the risk of developing osteoporosis, a condition characterized by brittle and fragile bones. Osteoporosis significantly raises the susceptibility to fractures and can have a severe impact on an individual’s mobility and quality of life.

Increased risk of fractures

Due to the decreased bone density associated with excess cortisol, individuals may be more prone to fractures, even with minor falls or trauma. This increased risk makes it crucial for those with chronically elevated cortisol levels to take proactive measures to protect their bone health and minimize the likelihood of fractures.

Skin Issues

Excess cortisol can also manifest in various skin issues, leading to discomfort and a negative impact on self-esteem. Understanding these effects can help individuals address any skin concerns related to cortisol levels.

Acne and skin inflammation

Elevated cortisol levels can contribute to the development or exacerbation of acne. Cortisol increases sebum production, promotes inflammation, and can interfere with the skin’s healing processes. This can result in breakouts, redness, and an overall decline in the skin’s appearance.

Reproductive System

Excess cortisol can disrupt the delicate balance of hormones in the reproductive system, leading to potential challenges and complications. Understanding these effects is crucial for individuals experiencing changes in their menstrual cycles or libido.

Irregular menstrual cycles

High levels of cortisol can disrupt the normal hormonal fluctuations involved in the menstrual cycle. This disruption can lead to irregular periods, unpredictable timing, or even absent menstruation. These changes can be distressing for individuals trying to conceive and may require professional consultation.

Decreased libido

Chronically elevated cortisol levels can also contribute to a decreased libido or loss of interest in sexual activity. Hormonal imbalances, fatigue, and reduced overall well-being can all contribute to a decline in sexual desire. Open communication with a healthcare professional can help identify the underlying causes and address any concerns.

Cardiovascular Health

Excess cortisol can have adverse effects on cardiovascular health, increasing the risk of developing heart disease and other related conditions. Understanding these impacts is essential to prioritize cardiovascular well-being.

Greater risk of heart disease

Elevated cortisol levels can promote inflammation, impair blood vessel function, and contribute to the development of atherosclerosis. These factors increase the risk of heart disease, including conditions such as coronary artery disease, heart attacks, and strokes. Managing cortisol levels and adopting heart-healthy lifestyle choices are crucial for maintaining cardiovascular health.
