The frequency of urinary tract infection peaks in the female population when they become sexually active. It is commonly caused by bacteria from the large bowel in the perineal region. While inadequate personal hygiene of the male and female partners, particularly before and after sex, is the usual culprit, menstruation, individual susceptibility and underlying pathological anomalies may account for some of the most intractable conditions that require thorough investigation and intensive medical intervention. Untreated or inappropriately managed repeated urinary tract infections, besides causing considerable stress and suffering, may also damage the kidneys and adversely affect pregnancy. The lady in question is likely to benefit from the advice of a specialist.
