In this podcast, the hosts discuss the relationship between laxative use and dementia risk, exploring the complexity of the topic. They delve into the different types of laxatives and their mechanisms of action. They also address factors affecting the gastrointestinal tract and the importance of addressing the underlying cause of constipation. Additionally, they provide insights on fiber intake, medication use, and how to improve bowel movements for optimal health.
Regular laxative use is associated with an increased risk of dementia, especially with osmotic laxatives.
Constipation should be viewed as a potential early sign of neurodegenerative diseases and addressed through comprehensive assessment and consultation with healthcare professionals.

Use of Laxatives and Risk of Dementia
A recent study examined the association between chronic use of laxatives and the risk of developing dementia. The study followed over 500,000 individuals for an average of 10 years and found that regular laxative use was associated with a 51% increased risk of dementia. The risk of dementia further increased with the number of laxative types used, with those using two or more types having a 90% increased risk. Osmotic laxatives, such as lactulose and Miralax, were identified as the most harmful. The study highlighted the importance of addressing constipation and the underlying factors causing it, as constipation itself may be an early sign of neurodegenerative diseases. However, it is important to consider other confounding factors and speak to a healthcare professional for personalized advice.
Complex Relationship Between Constipation, Laxatives, and Dementia
Constipation is a common issue often caused by factors like low fiber intake, dehydration, and underlying medical conditions. Regular laxative use is frequently seen as a remedy for constipation, but a recent study revealed a potential association between laxative use and an increased risk of dementia. However, it is essential to recognize that constipation itself can be an early sign of neurodegenerative diseases like Parkinson's and Alzheimer's. The study emphasized the need to address and investigate the underlying causes of constipation, such as lifestyle choices, medication side effects, and related health conditions. Moreover, it is crucial to consult with a healthcare professional to obtain personalized guidance and ensure a comprehensive approach to managing constipation and overall brain health.
Understanding the Complexity of Epidemiological Studies
The discussed study explored the relationship between laxative use and dementia risk using epidemiological data. While epidemiological studies provide valuable insights, it is important to approach them with caution due to various confounding factors and limitations. The study demonstrated that regular laxative use was associated with an increased risk of dementia, particularly osmotic laxatives. Nevertheless, there are several underlying factors involved, including overall gut health, fiber intake, medication side effects, and other medical conditions. Therefore, it is crucial to interpret epidemiological data in conjunction with comprehensive medical assessments and consultation with healthcare professionals.
Addressing Constipation and Promoting Gut Health
Constipation should be viewed as a significant health concern, even if it is mild, as it can indicate underlying issues and impact overall well-being. Lifestyle factors like fiber intake, hydration, exercise, and a balanced diet play a crucial role in maintaining digestive health. While laxatives may provide temporary relief, the focus should remain on addressing the root causes of constipation and promoting gut health. This involves considering dietary changes, identifying medication-related factors, and exploring potential underlying medical conditions. Consulting with healthcare professionals can help create personalized management strategies and ensure long-term gastrointestinal health.
This episode was part of a live discussion in the Science Club of the NEURO Academy. We discussed the recent article that showed an association between laxative intake and dementia, and critically analzed the methodology and the results for the audience. We then answered their questions.
