Anorexia nervosa is a condition which is associated with extremely low body weight and endocrine problems including persistent anovulation and a hypo-oestrogenic state. As the lower urinary tract is oestrogen sensitive, it is possible that women suffering from anorexia nervosa may experience similar distressing urinary problems. Of 29 anorexic women assessed, the majority had significant irritative urinary symptoms of which frequency, urgency and nocturia were the most common. These symptoms also had an unfavorable impact on their quality of life.
