Hyperphagia is a condition characterized by excessive hunger or increased appetite. It is often associated with eating disorders, such as binge eating disorder, as well as certain medical conditions like Prader-Willi syndrome and hypothalamic obesity. Research in the area of hyperphagia focuses on understanding the underlying causes of excessive hunger, the physiological mechanisms that regulate appetite, and potential interventions or treatments to manage or reduce hyperphagia. This research may involve studies on the neurobiological pathways involved in hunger and satiety, genetic factors that contribute to hyperphagia, and behavioral interventions to help individuals control their appetite and eating habits.
