Urinary tract infection is a common infectious disease in women, which can occur in women of any age, especially during pregnancy, is more likely to occur, which is related to the following reasons: First, after pregnancy, the body of women’s hormone secretion has changed, which will cause a corresponding increase in vaginal secretions. The female urethra is located in the vulva, and the vaginal opening and anus are very close, the increase in vaginal secretions will lead to a moist vulva, this environment is also very conducive to the breeding of bacteria, the urethra is also very easy to be infected accordingly. Secondly, the urine of pregnant women contains glucose, amino acids and other substances, which are also very conducive to the growth of bacteria, which will also lead to pregnant women more prone to urinary tract infections. Thirdly, as the uterus grows after pregnancy, it will compress the ureter and make it bigger, and the peristalsis will be weaker than usual, which will easily lead to poor urination and retention of urine, which over time will also make it difficult for bacteria to be discharged, making it easy for urinary tract infections to occur.
