Medical fact of the day:
Cushing’s syndrome often presents with a plethora of distinctive features such as a round “moon” face, central obesity, and the development of a “buffalo hump” due to fat accumulation. This syndrome is a result of prolonged exposure to high levels of cortisol, often due to prolonged corticosteroid use or adrenal gland abnormalities.

“Every patient is a story – listen carefully and you’ll write the chapter that brings them back to health.”
