Constipation is a common gastrointestinal issue that disproportionately affects women across all age groups. Dietary fiber and hydration are two critical factors in the management and prevention of constipation. This review explores the impact of fiber and hydration on constipation in women, emphasizing variations across life stages. The role of fiber types (soluble and insoluble), hydration levels, and age-related physiological changes are discussed in detail. Current literature is synthesized to identify trends, gaps, and practical recommendations for clinical interventions. Knowledge gaps and suggestions for future research are also highlighted.
