Analysis into potential lifestyle factors that may influence defecation frequency

Will Foldys


This paper aims to investigate the potential lifestyle factors that may influence the frequency of defecation and the biological mechanisms behind them. Taking data from a 2022 study into defecation frequency we looked at three common lifestyle factors that may affect defecation frequency. Sleep, Caffeine Consumption and Fruit and Vegetable consumption are all commonly associated with defecation frequency, but their effects are complicated and require further study.
