In fact, the study's results suggest that drinking coffee may reduce the risk of overactive bladder.
Researchers found that drinking tea only slightly increased women's risk of overactive bladder, or urinary incontinence - the inability to control the release of urine from the bladder.
"Coffee may reduce your risk of overactive bladder control problems."
Women who drank a lot of tea also had a slight increased risk of nocturia, or the need to get up more than once during the night to urinate. Surprisingly, women who drank a lot of coffee had a lower risk of urinary incontinence compared with women who did not drink coffee.
Giorgio Tettamanti, of the Karolinska Institutet in Sweden, and colleagues set out to study how drinking coffee and tea affects symptoms of urinary incontinence. In contrast to past findings that coffee and tea consumption increase people's risk of urinary incontinence, they found that the two caffeinated drinks have little impact on overactive bladder.
They surveyed 14,031 female twins who had at least one symptom of urinary problems.
