Butyrate Yogurt for Cancer Constipation

Plain-language summary

Constipation is a common yet underrecognized supportive care issue in cancer patients. Its consequences extend beyond physical discomfort to include impaired quality of life, reduced opioid adherence leading to inadequate analgesia, and increased risks of fecal impaction, emergency visits, and hospitalization. Current management strategies-including laxatives, stool softeners, prokinetics, and PAMORAs-remain suboptimal due to limited effects on gut dysbiosis, mucosal barrier dysfunction, and chronic inflammation, as well as issues related to polypharmacy, variable efficacy, and long-term tolerability. Hence, there is a clear need for novel, well-tolerated, long-term interventions with nutritional benefits that target the gut microbiota-mucosal barrier-motility axis. Short-chain fatty acids (SCFAs), particularly butyrate, are key microbial metabolites that may improve constipation through multiple mechanisms: enhancing intestinal motility via enteric nervous system regulation, reinforcing mucosal barrier integrity and mitigating low-grade inflammation, and restoring gut microbial-metabolite homeostasis. Butyrate supplementation therefore holds mechanistic promise for cancer-related constipation. The "Small Blue Can High Dietary Fiber Butyrate SCFA Yogurt" (Blueglass) is designed with a "probiotics + prebiotics + acids" synergistic fermentation platform, delivering ≥70 mg/100 g butyrate combined with high dietary fiber. Compared with conventional laxatives or single-agent butyrate, this yogurt-based formulation offers potential advantages in patient acceptability, long-term adherence, dual exogenous and endogenous SCFA support, and multi-target action on motility, microbiome, and barrier function, making it a promising candidate for supportive care in this population.
