Daily bowel movements linked to better long-term health, study finds
A new study in Cell Reports Medicine reveals that bowel movement frequency plays a key role in long-term health. Researchers found that having one or two bowel movements daily is linked to the best physiological outcomes. The findings also highlight how irregular habits, such as constipation or diarrhoea, may raise risks for serious conditions.
The study confirms that a regular pattern of one to two daily bowel movements supports a healthy gut. People within this range tend to host more fibre-fermenting bacteria, known as strict anaerobes, which thrive on plant-based diets. These microbes contribute to better digestion and overall well-being.
Certain groups naturally experience fewer bowel movements. Younger individuals, women, and those with a lower body mass index often have less frequent habits. Meanwhile, diets rich in fruits, vegetables, and water—alongside regular exercise—help maintain the ideal frequency. Irregular bowel patterns carry risks. Constipation allows harmful toxins, like p-cresol sulfate and indoxyl sulfate, to build up in the blood due to excessive protein fermentation. Diarrhoea, on the other hand, can lead to bile acid loss, triggering inflammation and potential liver damage. Over time, chronic constipation has been linked to higher infection risks, while persistent diarrhoea may contribute to neurodegenerative conditions. To explore these connections further, scientists are planning a large clinical trial. The study will track bowel movements in a diverse group over an extended period to assess whether managing frequency could help prevent disease.
The research reinforces that a daily bowel movement pattern of once or twice is optimal for health. Simple lifestyle changes, such as a plant-heavy diet and hydration, can help achieve this balance. Future trials may provide clearer guidance on how bowel habits could influence disease prevention.
