Nocturnal polyuria in women is more likely to be the result of urological disorders, reproductive disorders, and abnormal mental states, as detailed below.
First, urinary system disorders. Women have a shorter urethra and are more prone to urinary tract infections compared to men. Symptoms such as frequent urination, urgency, painful urination, urinary incontinence and difficulty in urination are common. The spread of urinary tract infections to other organs can lead to cystitis and nephritis, which can also induce the manifestation of nocturnal polyuria. In addition, interstitial cystitis tends to lead to reduced bladder capacity, decreased compliance and reduced contractile function, which also induce nocturnal polyuria in women. In conclusion, urological disorders are the most common cause of nocturnal polyuria in women, and patients with nocturnal polyuria caused by urological disorders account for the majority of cases.
Secondly, diseases of the reproductive system. Vaginitis, pelvic inflammatory disease and adnexitis can adversely affect women’s urination, and increased nocturia is a common symptom.
Thirdly, some female patients with symptoms of nocturnal polyuria are caused by mental factors. Patients have common triggers such as excessive mental stress, shock and irritation.
