Can Statins Cause Constipation?
Statins and Gastrointestinal Adverse Events
Statins, widely prescribed for lowering cholesterol, have been associated with various gastrointestinal side effects. Commonly reported issues include abdominal pain, diarrhea, and constipation. However, the prevalence and significance of these conditions as primary outcomes have not been extensively studied.
Retrospective Cohort Study on Statins and Constipation
A comprehensive retrospective cohort study aimed to determine if statin therapy is associated with gastrointestinal conditions such as constipation, abdominal pain, diarrhea, and colitis. The study analyzed data from a regional military healthcare system, comparing 6342 statin users with 6342 non-users. The results showed no statistically significant difference in the occurrence of constipation between statin users and non-users (OR, 0.96; 95% CI, 0.87–1.05; P = .33). This suggests that statins do not significantly increase the risk of constipation.
Lovastatin and Irritable Bowel Syndrome with Constipation (IBS-C)
Interestingly, another study explored the potential benefits of lovastatin lactone in treating irritable bowel syndrome with constipation (IBS-C). Methane production by the methanoarchaeon Methanobrevibacter smithii has been linked to constipation and IBS-C. Lovastatin, known for its cholesterol-lowering effects, may also inhibit enzymes in the methanogenesis pathway, thereby reducing methane production and alleviating constipation symptoms. This dual action of lovastatin could offer therapeutic benefits for patients with IBS-C, although it does not imply that statins cause constipation.
Conclusion
In summary, while statins are associated with various gastrointestinal side effects, current research indicates that they do not significantly increase the risk of constipation. On the contrary, lovastatin may even help alleviate constipation in patients with IBS-C by inhibiting methane production. Therefore, concerns about statins causing constipation may be unfounded based on the available evidence .
