Which condition is characterized by increased cortisol levels?

• A. Addison's disease
• B. Hypothyroidism
• C. Cushing's syndrome
• D. Diabetes mellitus

Answer: (C)

Cushing's syndrome is characterized by an excessive production of cortisol, typically due to prolonged exposure to high levels of this hormone. Cortisol is a steroid hormone produced by the adrenal glands, and its functions include regulation of metabolism, immune response, and blood pressure. In Cushing's syndrome, high cortisol levels can lead to a range of symptoms such as weight gain, particularly around the abdomen and face (often referred to as a "moon face"), thinning skin, easy bruising, muscle weakness, and other metabolic changes. The increased cortisol levels can result from various factors, including adrenal tumors, pituitary adenomas secreting adrenocorticotropic hormone (ACTH), or ectopic ACTH production from tumors outside of the pituitary gland. This condition stands in contrast to Addison's disease, which is associated with decreased cortisol levels due to adrenal insufficiency. Hypothyroidism is related to low levels of thyroid hormones, and diabetes mellitus primarily involves disturbances in glucose metabolism rather than alterations in cortisol. Thus, the specific nature of increased cortisol levels is quintessential in diagnosing Cushing's syndrome.
