What are signs of high cortisol?
Short answer: High cortisol often shows as persistent fatigue with poor sleep, increased abdominal weight and appetite, elevated blood pressure and blood sugar, mood changes (anxiety or irritability), and physical signs like thin skin or easy bruising. It can also cause irregular periods, reduced libido, and more frequent infections.
Explanation
cortisol is a stress hormone produced by the adrenal glands that helps regulate metabolism, immune response, blood pressure, and the sleep–wake cycle. Chronically elevated cortisol (from prolonged stress, certain medications, or adrenal/ pituitary disorders) shifts metabolism toward increased glucose production and fat storage—especially centrally—suppresses immune function, disrupts sleep, and alters mood and cognition. Persistent elevation can lead to insulin resistance, hypertension, muscle weakness, skin thinning, and reproductive irregularities. Diagnosis is by clinical assessment and tests (saliva, blood, urine, or dexamethasone suppression), guided by a clinician.
Tips
- Prioritize sleep and consistent sleep–wake times to help normalize cortisol rhythms.
- Use stress-reduction techniques (deep breathing, mindfulness, cognitive strategies) daily.
- Engage in regular moderate exercise; avoid chronic excessive high-intensity training which can raise cortisol.
- Limit stimulants and excess sugar; eat balanced meals with protein, fiber, and healthy fats.
- See a healthcare provider for evaluation, medication review, and appropriate cortisol testing if symptoms are persistent or severe.
