excessive cortisol in the bloodstream, often due to stress or illness
High cortisol levels, also known as hypercortisolism, refer to an excessive amount of cortisol in the bloodstream. Cortisol is a hormone produced by the adrenal glands that helps regulate metabolism, immune response, and stress. Elevated cortisol can result from chronic stress, certain medications, or medical conditions like Cushing's syndrome, and may lead to symptoms such as weight gain, high blood pressure, and thinning skin.
