Hunger regulation in obesity

The regulation of hunger is often disrupted in individuals with obesity, making it challenging to manage food intake. The hypothalamus, a region of the brain that controls appetite and energy balance, plays a crucial role in hunger regulation. In obesity, hormonal signals that control hunger, such as ghrelin (which stimulates appetite) and leptin (which signals satiety), can become imbalanced. For instance, leptin resistance, where the brain no longer responds to leptin’s fullness signal, leads to constant hunger. Simultaneously, elevated levels of ghrelin can increase appetite, contributing to overeating. This dysregulation of hunger signals can perpetuate the cycle of weight gain, making it difficult for individuals to maintain a healthy weight. Addressing these disruptions through medical treatments or lifestyle changes that target hormonal balance can be an effective strategy for managing obesity and promoting weight loss.
