was bedeutet low cortisol — what symptoms are typical?

Low cortisol (hypocortisolism) typically indicates adrenal insufficiency (Addison's disease or secondary forms). Common symptoms include persistent fatigue, muscle weakness, weight loss, low blood pressure (especially upon standing), nausea, abdominal pain, salt craving, hyperpigmentation (in primary insufficiency), and reduced stress tolerance. Mood changes, irritability, and depressive symptoms may also occur. Diagnosis requires clinical evaluation with cortisol day profiles, ACTH stimulation tests, and imaging if needed. Single case reports or genetic variants (e.g., MAOA) do not provide sufficient evidence for cortisol assessment. The provided context lacks specific information on cortisol symptoms, so this answer is based on general medical knowledge. If you suspect low cortisol, consult a physician for proper testing and treatment.
