During a woman's menstrual period, hormonal levels in the body change, particularly with increased secretion of prostaglandins, which can stimulate gastrointestinal motility, causing it to accelerate. This may lead to feelings of hunger. Additionally, psychological changes during menstruation—such as increased anxiety and insomnia—can indirectly stimulate appetite, enhancing sensations of hunger and leading to increased food intake.
