What You'll Learn

Low cortisol and Addison's disease
Cortisol is a hormone produced by the adrenal glands, which are located just above the kidneys. Cortisol helps break down fats, proteins, and carbohydrates in the body, controls blood pressure, and affects the immune system. A low cortisol response to stress is associated with musculoskeletal pain and increased pain sensitivity in young adults.
Addison's disease, also known as primary adrenal insufficiency, is a rare chronic condition in which the adrenal glands do not produce enough cortisol and aldosterone hormones. It can occur at any age and is most often caused by an autoimmune attack. The symptoms of Addison's disease include weakness, fatigue, weight loss, and dark patches on the skin. It is often diagnosed through blood tests that measure sodium, potassium, cortisol, and ACTH levels, as well as CT scans that evaluate the adrenal and pituitary glands.
The treatment for Addison's disease involves replacing the missing hormones with synthetic versions, such as corticosteroids, which may need to be taken for life. Fludrocortisones may also be prescribed to help maintain normal sodium and potassium levels. In cases of acute adrenal insufficiency or an Addisonian crisis, which can be triggered by stress, illness, fever, surgery, or dehydration, treatment may begin with intravenous fluids and medications.
Secondary adrenal insufficiency, on the other hand, occurs when the pituitary gland doesn't produce enough ACTH, leading to a decrease in cortisol production by the adrenal glands. This form of adrenal insufficiency can be diagnosed through an insulin-induced hypoglycemia test, which measures blood sugar and cortisol levels before and after the injection of insulin.

Cortisol and stress
Cortisol is a steroid hormone produced by the adrenal glands, which are located on top of the kidneys. It plays a critical role in the body's response to stress and affects almost every organ and tissue in the body. During stressful events, the body releases "fight or flight" hormones, such as adrenaline, and then releases cortisol to keep the body on high alert. Cortisol also triggers the release of glucose from the liver, providing fast energy during stressful situations.
Chronic stress has been linked to the development and progression of various illnesses, including neurodegenerative diseases like Alzheimer's and Parkinson's. Excessive cortisol production and HPA axis dysregulation, along with neuroinflammation, are believed to drive these conditions. Additionally, abnormal cortisol patterns are associated with heightened pain sensitivity and susceptibility in individuals experiencing chronic pain.
Low cortisol levels have been linked to musculoskeletal pain and increased pain sensitivity in young adults. A study found that an abnormal hypothalamic-pituitary-adrenal (HPA) axis response to psychosocial stress at 18 years of age was associated with musculoskeletal pain and increased pain sensitivity at 22 years of age. Addison's disease, a rare disorder, is another condition associated with low cortisol levels. It occurs when the adrenal glands do not produce sufficient cortisol and aldosterone hormones.
While cortisol is often associated with stress, it is important to recognize that it is a necessary hormone with various functions in the body. However, both high and low levels of cortisol can negatively impact an individual's health. Strategies such as regular physical activity, deep breathing exercises, laughter, and maintaining healthy relationships can help manage stress and, consequently, cortisol levels.

Low cortisol and hypothyroidism
Several studies have found a link between low cortisol levels and muscle pain. One study found that a low cortisol response to stress is associated with musculoskeletal pain and increased pain sensitivity in young adults.
Low cortisol levels are associated with hypothyroidism, an endocrine disorder characterised by insufficient thyroid hormone production. This can be diagnosed through laboratory tests that measure blood levels of thyroid-stimulating hormones (TSH), T3, and T4. High levels of TSH and low levels of T3 and T4 indicate a problem with the thyroid gland.
The thyroid and the adrenal glands, which produce cortisol, are linked through the hypothalamic-pituitary-adrenal (HPA) axis. Studies have shown that hypothyroidism is associated with higher cortisol levels, believed to be caused by decreased clearance of cortisol from the body. This may be due to the complex feedback mechanisms between the hypothalamus, pituitary gland, adrenal cortex, and thyroid gland.
However, other studies have found that hypothyroidism is associated with lower cortisol levels. Adrenal insufficiency, which can be a secondary effect of hypothyroidism, is characterised by low cortisol levels. Chronic physical and emotional stress caused by hypothyroidism may lead to adrenal fatigue, contributing to low cortisol levels.
Treatment for hypothyroidism typically involves administering artificial thyroid hormones to normalise levels. Adrenal insufficiency is also treated with hormone supplementation, including glucocorticoids like hydrocortisone or prednisolone to replace cortisol.

Low cortisol and pain sensitivity
Cortisol is a potent anti-inflammatory hormone that is released as a response to inflammatory, emotional, or physical stress. It functions to mobilize glucose reserves for energy and modulate inflammation. Cortisol also facilitates the consolidation of fear-based memories for future survival and the avoidance of danger.
Chronic stress-induced hypocortisolism has been linked to pain somatization disorders, such as fibromyalgia, chronic fatigue syndrome, chronic pelvic pain, and temporomandibular disorder. Long-term stress has been shown to contribute to morning fatigue, pain, and inflammation. Similarly, hypocortisolism has been associated with low back pain, and a low cortisol awakening response has been linked to leg pain intensity, pain catastrophizing, and low coping scores in patients diagnosed with lumbar disk herniations.
Several reports in the literature have identified an association between cortisol levels and the presence of chronic pain in conditions such as rheumatoid arthritis, low back pain, or whiplash. A study of 805 participants investigated whether an abnormal hypothalamic-pituitary-adrenal (HPA) axis response to psychosocial stress at 18 years of age is associated with musculoskeletal (MS) pain and increased pain sensitivity at 22 years of age. The results showed that a low cortisol response to stress is associated with musculoskeletal pain combined with increased pain sensitivity in young adults.
Patients with chronic pain who are most likely to have abnormal cortisol serum concentrations are those with central pain, which is constant and not provoked or worsened by any stimulus such as movement, pressure, or stress. These patients typically complain of insomnia and periodic episodes of allodynia (pain to light touch) and/or hyperalgesia (extra pain on pressure). Cortisol screening is highly recommended for these patients as an adjunctive evaluation tool.

Low cortisol and autoimmune disease
Cortisol is a stress hormone that helps regulate sleep patterns and immune system function. Prolonged periods of stress can cause low hormone reserve, resulting in overall low cortisol levels. This can lead to a condition called Addison's disease, also known as autoimmune adrenalitis, where the adrenal glands don't produce enough cortisol and aldosterone hormones. This disease is often caused by an autoimmune attack where the immune system attacks the adrenal cortex, impairing hormone production. Symptoms of Addison's disease include weakness, fatigue, and weight loss, darkened skin areas, and orthostatic hypotension, which can be life-threatening in times of stress, leading to a condition called an adrenal crisis.
Low cortisol levels have been linked to autoimmune diseases, with stress playing a significant role. People with autoimmune diseases may experience flares or worsening of their condition after stressful events or prolonged periods of low-grade stress. Stress can cause a decrease in cortisol levels, affecting the immune system's function and the regulation of inflammation, metabolism, blood sugar, and blood pressure.
Several methods can be employed to manage low cortisol levels and their impact on autoimmune diseases. Cortisol testing through saliva or blood tests can help identify low levels. Eliminating stress, meditation, biofeedback, and short periods of exercise can help increase cortisol levels. Working with a healthcare provider is essential to increase cortisol levels without stimulating anxiety and to explore herbal therapies and hormone precursors like pregnenolone.
Additionally, individuals with Addison's disease may need to carry identification and medical alert jewelry. They should regularly consult a healthcare provider, especially during stressful events, as medication dosages may need adjustment. In emergencies, a shot of cortisol may be necessary to manage the condition.
