Studies have shown that if women drink more than four cups of coffee a day or consume too much caffeine, their bladder muscles are weak, that is, the probability of bladder dysfunction is more than twice that of other women, and bladder dysfunction is the main cause of urinary incontinence. The researchers studied the relationship between caffeine and urinary incontinence in 13 1 women who drank caffeinated drinks and had bladder dysfunction and 128 women who did not have this problem.
