Telítettségérzet

Telítettségérzet, often translated as "feeling of fullness" or "satiety," is a complex physiological and psychological sensation that signals the body has consumed enough food. It plays a crucial role in regulating food intake and preventing overeating. This feeling is initiated by a variety of signals from the digestive system and the brain.

As food enters the stomach, the stomach wall stretches, sending signals to the brain via the vagus nerve. Hormones like ghrelin, often called the "hunger hormone," decrease as satiety increases, while hormones such as leptin, peptide YY, and cholecystokinin are released and contribute to the feeling of fullness. The presence of nutrients in the small intestine also triggers the release of satiety-promoting hormones.

Beyond these physiological responses, psychological factors also influence telítettségérzet. The sight, smell, and taste of food, as well as learned behaviors and social contexts surrounding eating, can impact how full a person feels. The brain integrates these various signals to create the subjective experience of being satisfied after a meal. Disruptions in these signaling pathways can lead to issues with appetite regulation, potentially contributing to conditions like obesity or eating disorders. Understanding telítettségérzet is key to comprehending the intricate mechanisms that govern our eating habits.
