The Effects of Prune Juice on Bowel Movement Patterns, Constipation Symptoms, and Quality of Life

This study investigates the effects of different prune juice dosages on bowel movement patterns, constipation symptoms, and quality of life in older adults. Using a factorial experimental design, 90 participants aged 65 to 100 with functional constipation will be randomly assigned to receive 100 mL, 150 mL, or 200 mL of prune juice daily for four weeks. The study aims to determine a safe and effective dosage for constipation management, offering a non-pharmacological approach to improving bowel health in older adults.
