Final answer:
The physical characteristics of someone with Cushing's syndrome include a moon face and buffalo hump due to the overproduction of cortisol, leading to high cortisol levels. Option (b), which states moon face and high cortisol levels, is the correct answer.
Step-by-step explanation:
The physical characteristics of someone with Cushing's syndrome include a moon face, due to a build-up of fat in the facial area, and a buffalo hump on the back of the neck, as well as rapid weight gain and hair loss. These symptoms stem from an overproduction or hypersecretion of the hormone cortisol. This condition is often associated with high blood glucose levels, slow growth, weak muscles, bone pain, and fatigue. The treatment focuses on reducing high cortisol levels, which can be the result of a variety of factors, including a pituitary tumor causing excessive secretion of ACTH (adrenocorticotropic hormone).
Thus, the correct answer to the question regarding the physical characteristics of someone with Cushing's syndrome and the involved hormone levels is (b) Moon face and high cortisol levels.
