<p>In recent years, excessive fluid intake by women has emerged as a well-being misconception without robust scientific support but may have an adverse impact on treatment outcome of overactive bladder (OAB) syndrome. Excessive fluid intake may have potential disadvantages as overhydration leads to exacerbation of symptoms of OAB particularly frequency, nocturia, and urgency.
