Question

how do tea and coffee result in increased urine output

Answer 1

Women with a high coffee intake were at lower risk of any urinary incontinence (OR 0.78, 95% confidence intervals (CI) 0.64-0.98) compared to women not drinking coffee. Coffee intake and incontinence subtypes showed no significant associations whereas high tea consumption was specifically associated with a risk for overactive bladder (OR 1.34, 95% CI 11.07-1.67) and nocturia (OR 1.18, 95% CI 1.01-1.38). Results from co-twin control analysis suggested that the associations observed in logistic regression were mainly due to familial effects.

Conclusions
This study suggests that coffee and tea consumption has a limited effect on urinary incontinence symptoms. Familial and genetic effects may have confounded the associations observed in previous studies.
