What role does Ghrelin play in the body?

• A. It acts as a satiety hormone
• B. It regulates blood glucose levels
• C. It is a hunger-arousing hormone secreted by an empty stomach
• D. It helps in the production of bile

Answer: (C)

Ghrelin is primarily known as a hunger-arousing hormone. It is produced by the stomach when it is empty, signaling to the brain that it is time to seek food. This hormone increases appetite and plays a crucial role in energy balance and hunger regulation. When the stomach is stretched after eating, ghrelin levels decrease, promoting satiety. Therefore, its main function focuses on stimulating hunger rather than suppressing it or regulating blood glucose levels. The correct choice highlights ghrelin's role as an important player in the body’s hunger signaling mechanism, making it essential for understanding appetite regulation and energy homeostasis.
