Low cortisol can cause persistent fatigue, dizziness, muscle weakness, low blood pressure, and difficulty recovering from illness or physical stress. Because cortisol helps regulate blood sugar, circulation, inflammation, and the body's stress response, insufficient production can affect nearly every system in the body.
Natural approaches such as adequate nutrition, hydration, and correcting nutrient deficiencies may help support overall health. Licorice root is also of interest because it influences how cortisol is metabolized. However, medically confirmed cortisol deficiency, known as adrenal insufficiency, requires appropriate medical treatment. Understanding the difference between low cortisol and ordinary stress-related fatigue is essential before choosing a remedy.
Low Cortisol at a Glance
Common symptoms: Fatigue, dizziness, low blood pressure, weakness, nausea, and unexplained weight loss.
Possible causes: Addison's disease, pituitary disorders, or suppression of cortisol production following corticosteroid use.
Natural support: Adequate vitamin C, B vitamins, protein, hydration, and appropriate electrolyte intake.
Herb of interest: Licorice root can increase cortisol activity in certain tissues but may cause serious side effects.
Diagnosis: Morning blood cortisol, ACTH testing, and sometimes an ACTH stimulation test.
Cortisol is produced by the adrenal glands, located above the kidneys. Levels normally rise in the early morning and decline throughout the day. This rhythm helps regulate energy availability, blood pressure, and the body's response to physical stress.
