Cortisol is a potent anti-inflammatory hormone that is released in response to threats of harm or danger. It is also known as the stress hormone. Cortisol dysfunction can cause an unmodulated inflammatory response, leading to oxidative and nitrosative stress, free radical damage, cellular death, aging, and systemic tissue degeneration. Signs of cortisol dysfunction include bone and muscle breakdown, fatigue, depression, pain, and memory impairments. Studies have shown that low cortisol levels are associated with musculoskeletal pain and increased pain sensitivity in young adults. Cortisol levels can be measured through blood, urine, and saliva tests, and imaging tests can be used to check for tumors or other abnormalities in the pituitary and adrenal glands, which regulate cortisol production.

What You'll Learn
Low cortisol levels can cause increased pain sensitivity
Cortisol is a hormone that affects nearly every organ system in the body. It is often referred to as the "stress hormone" because it is released by the body in response to threats of harm or danger. However, it also has several other functions, including regulating blood pressure and metabolism. Cortisol is produced by the adrenal glands, which are located above each kidney.
While everyone experiences high cortisol levels from time to time, consistently high cortisol levels can indicate an underlying health problem, such as Cushing syndrome, adrenal gland tumours, or pituitary gland issues. On the other hand, lower-than-normal cortisol levels (hypocortisolism) can be caused by adrenal insufficiency, which can be primary or secondary. Primary adrenal insufficiency, also known as Addison's disease, occurs when the immune system attacks the adrenal glands, or due to an infection or blood loss to the adrenal gland tissue. Secondary adrenal insufficiency is associated with an underactive pituitary gland (hypopituitarism) or a pituitary tumour.
Low cortisol levels have been linked to various health issues, including low blood pressure, fatigue, and muscle weakness. Additionally, research suggests that a low cortisol response to stress may be associated with musculoskeletal pain and increased pain sensitivity, particularly in young adults. One study found that individuals with abnormal hypothalamic-pituitary-adrenal (HPA) axis responses to psychosocial stress at 18 years of age were more likely to experience musculoskeletal pain and increased pain sensitivity at 22 years of age. However, more research is needed to establish a causal relationship between low cortisol levels and pain sensitivity.
Furthermore, a chronic stress response to pain or non-pain-related stressors can initiate or prolong the pain experience and impair healing. Acute pain can trigger cortisol secretion, but repeated or exaggerated cortisol secretion following maladaptive responses to acute pain can lead to hypocortisolism and chronic, recurrent pain. Cortisol dysfunction can also contribute to widespread inflammation, which has been implicated in various diseases, including rheumatoid arthritis, fibromyalgia, and chronic low back pain. Therefore, it is crucial to address stress management and consider screening for non-pain-related stress to facilitate effective treatment and prevent chronic disability.

Cortisol dysfunction can lead to bone and muscle breakdown
Cortisol is commonly known as the stress hormone, and it has several other important functions in the body. Cortisol dysfunction can lead to bone and muscle breakdown, a condition known as hypocortisolism or adrenal insufficiency. This can be caused by an underactive pituitary gland or a pituitary tumour, limiting ACTH production and, in turn, cortisol production.
In humans, cortisol dysfunction has been linked to various diseases, including osteoporosis, rheumatoid arthritis, myopathy, fibromyalgia, and chronic low back pain. Cortisol is an anti-inflammatory hormone, and when it fails to function properly, the body experiences an unmodulated inflammatory response to physical pathogens, unrecognized proteins, or psychological stressors. This inflammation can lead to oxidative and nitrosative stress, free radical damage, cellular death, aging, and systemic tissue degeneration.
Acute pain can trigger cortisol secretion, and if this response is repeated due to maladaptive cognitive responses to acute pain, it can lead to hypocortisolism and chronic, recurrent pain. This cycle of pain and cortisol secretion can impair healing and lead to prolonged pain experiences.
Additionally, glucocorticoids, a group of hormones that include cortisol, have been shown to have direct and indirect effects on bone and muscle. Therapeutic glucocorticoids might lead to bone loss through their direct actions and interactions with the underlying disease being treated. For example, glucocorticoid excess adversely impacts fat metabolism, leading to central fat accumulation and increased insulin resistance, which can affect bone and muscle health.
In summary, cortisol dysfunction can lead to bone and muscle breakdown through various mechanisms, including inflammation, glucocorticoid interactions, and the body's stress response. This can result in a range of painful conditions and chronic disability for those affected.

Hypocortisolism may be caused by an underactive pituitary gland
Cortisol is a potent anti-inflammatory hormone. Its failure to function results in an unmodulated inflammatory response to pathogens, unrecognized proteins, or psychological stressors. Inflammation induces oxidative and nitrosative stress, free radical damage, cellular death, ageing, and systemic tissue degeneration. Signs and symptoms of stress-induced cortisol dysfunction include bone and muscle breakdown, fatigue, depression, pain, memory impairments, and sodium-potassium. Acute pain is a stressful stimulus that elicits cortisol secretion and is commonly associated with hypercortisolism. Repeated or exaggerated cortisol secretion following maladaptive responses to acute pain or non-pain-related stressors can lead to hypocortisolism and chronic, recurrent pain.
Hypocortisolism, or hypopituitarism, is a rare condition in which the pituitary gland does not produce enough of one, multiple, or all of the required hormones. The pituitary gland works in conjunction with the hypothalamus, which signals the release of specific hormones and regulates functions like blood pressure, heart rate, body temperature, and digestion. If an individual has a disease or injury that affects the pituitary gland or hypothalamus, they may develop hypopituitarism. The condition can arise suddenly after an injury or develop slowly over months or years.
The symptoms of hypopituitarism depend on which hormones are deficient. Not enough ACTH (adrenocorticotropin hormone) can lead to an underactive adrenal gland, causing low blood pressure, low blood sugar, fatigue, and increased stress sensitivity. A deficiency in growth hormone can result in a loss of bone and muscle mass in adults and stunted growth or dwarfism in children. Insufficient thyroid-stimulating hormone can lead to an underactive thyroid, causing fatigue, confusion, difficulty with temperature regulation, weight gain, constipation, and dry skin.
Treatment for hypopituitarism aims to restore normal function to the pituitary gland and may include hormone replacement therapy, surgery to remove tumours, or radiation therapy.

Acute pain can cause cortisol secretion
Acute pain is a stressful stimulus that is likely to cause cortisol secretion. Cortisol is a potent anti-inflammatory hormone that is secreted during an acute stress response. It serves to mobilise glucose reserves for energy, inhibit pain and non-vital organ systems, and promote an adaptive fight-or-flight response.
When acute pain occurs, the HPA axis is stimulated, causing a rise in corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), catecholamines, and serum cortisol. Cortisol secretion during a stress event may distract attention from a concurrent painful stimulus through its anti-inflammatory effects, allowing for life-preserving actions to occur despite the pain. This protective mechanism supports adaptive survival measures.
Variations in initial cortisol levels at the time of a pain event can influence the trajectory of pain resolution. Individuals with higher reactive cortisol responses tend to report less pain during stressful experiences, indicating that cortisol acts as a protective mechanism against pain. However, a maladaptive response to acute pain may intensify the pain experience and condition a sensitized physiologic stress response to pain-provoking stimuli.
Chronic exposure to excess serum cortisol can lead to serious health risks, similar to Cushing's syndrome, including hyperlipidemia, diabetes, osteopenia/osteoporosis, dental decay, weight gain, and mental deterioration. Conversely, low cortisol levels resulting from prolonged stress responses can also contribute to chronic pain and disability.
While the relationship between pain, stress, and cortisol is complex and not fully understood, it is clear that acute pain can trigger cortisol secretion, which can have both protective and detrimental effects depending on the context and the individual's response to stress.

Chronic stress can cause cortisol dysfunction
Cortisol is commonly known as the stress hormone. It is an essential hormone that impacts several aspects of the body. Acute pain or non-pain-related stressors activate a normal physiological stress response, which includes the short-term sympathetic release of epinephrine and norepinephrine, followed by the secretion of cortisol. This anti-inflammatory hormone helps to regulate how the body uses glucose for energy. In short bursts, cortisol can boost immunity by limiting inflammation.
However, a maladaptive response to acute pain or non-pain-related stressors can cause excessive or prolonged cortisol secretion, leading to cortisol dysfunction. This can result in unmodulated inflammation, which may contribute to a cycle of inflammation, depression, and pain. Chronic stress can cause cortisol dysfunction, which may initiate, exacerbate, or prolong the pain experience, impair healing, and lead to chronic disability. For example, short-term exaggerated responses to daily stressors may cause repeated short-term surges of cortisol secretion that rapidly exhaust cortisol levels, presenting as recurrent episodes of hypercortisolism followed by hypocortisolism and pain. Alternatively, a prolonged or constant low-amplitude stress response may lead to constant pain.
Signs and symptoms of stress-induced cortisol dysfunction include bone and muscle breakdown, fatigue, depression, pain, memory impairments, and sodium-potassium imbalances. Cortisol dysfunction has been implicated in various diseases, including osteoporosis, rheumatoid arthritis, myopathy, fibromyalgia, chronic fatigue syndrome, chronic pelvic pain, and temporomandibular joint dysfunction.
If you are concerned about daily stress levels and potential cortisol dysfunction, there are several strategies to manage stress and lower cortisol levels. These include getting quality sleep, regular physical activity, deep breathing exercises, and engaging in enjoyable activities that promote laughter and the release of endorphins.
