wie kann man den cortisolspiegel messen — when to see a doctor?

Cortisol is typically measured via blood, saliva, or urine. Blood and saliva tests capture the diurnal rhythm (highest in the morning), while a 24-hour urine test measures total daily output. You should see a doctor if you experience symptoms such as unexplained weight gain, high blood pressure, muscle weakness, mood swings, or chronic fatigue. Medical evaluation is also warranted if Cushing's syndrome (overproduction) or Addison's disease (underproduction) is suspected. Home test kits can provide orientation, but interpretation is complex – cortisol levels fluctuate widely and are influenced by stress, sleep, and medications. A single elevated reading does not automatically indicate disease. Evidence is based on clinical practice, not on the provided context. Safety note: Seek immediate medical attention for acute symptoms like sudden weakness, dizziness, or chest pain.
