gherlin

Ghrelin is a hormone produced mainly in the stomach that signals hunger to the brain, stimulating appetite and encouraging eating. It plays a key role in regulating energy balance by increasing food intake when the body needs fuel. Ghrelin levels rise before meals and decline after eating. Besides influencing hunger, it also affects mood, sleep, and even growth hormone release. Its activity helps maintain an energy cycle, ensuring the body gets enough nutrients to function properly.
