This study looked at the association between 25-hydroxyvitamin D (vitamin D) status and pelvic floor symptom distress and impact on quality of life. The results found that vitamin D levels were lower in women with pelvic floor disorder symptoms. Insufficient vitamin D was found to be associated with increased colorectal symptom distress and greater impact of urinary incontinence on quality of life. The authors suggest "vitamin D insufficiency may result in the reduced ability to voluntarily control stress leakage and decreased effectiveness for urge suppression strategies. Sufficient vitamin D serum levels may facilitate an increase in pelvic floor muscle efficiency and decrease in detrusor contractibility, allowing for a more effective response to behavioral therapy by decreasing urinary incontinence episodes".
