What causes urinary tract infection in girls?

In daily life, urinary tract infection is a relatively common disease, and women are more likely to suffer from urinary tract infection. Urinary tract infection in women will not only have a certain impact on their physical health, but also easily lead to some complications and gynecological diseases. There are many causes of urinary tract infection in women, which may generally be caused by lack of attention to hygiene or postpartum bacterial growth.

What causes urinary tract infection in women?

1. Pregnancy. During pregnancy, the enlarged uterus will press closer to the bladder and ureters. Endocrine changes also cause the ureteral dilation and peristalsis to slow down, causing a slow urine flow or the formation of a mild effusion. This situation also facilitates bacterial invasion and reproduction, causing disease. In the past, some people used antibiotics for prevention, but this method is not advisable. Because the misuse of antibiotics may have certain negative effects on the mother and fetus, not to mention the long ten months of pregnancy, it is difficult to prevent.

2. The sanitary ware is unhygienic. It often occurs on campus among girls living in dormitories. Their towels are hung behind the door and piled together. They are not exposed to sunlight all year round and the environment is humid, which easily breeds bacteria and mold, leading to repeated infections.

3. Pathogens. The most common is Escherichia coli, followed by Klebsiella, Proteus, Streptococcus faecalis, Micrococcus and Pseudomonas aeruginosa. This is one of the causes of urinary tract infections.

4. Menstruation and sexual activity. Menstrual blood is the best culture medium for bacteria. Menstrual hygiene, especially the cleaning and disinfection of menstrual products, is an important part of reducing bacterial invasion. Sexual intercourse can push bacteria from the anterior urethra into the posterior urethra and bladder through mechanical pushing action.

5. Women over 50 years old have reached menopause, their vaginal secretions are alkaline, and they lack IgA, so it is difficult to inhibit the growth and reproduction of urinary tract bacteria, causing serious and difficult to cure urinary tract infections.

6. Hold your urine. This is a common bad habit among women. This will lead to two adverse consequences. First, urine stays in the bladder for a long time. If a small amount of bacteria invade, they have more time to multiply and invade the tissues. Second, when the bladder is full, the pressure increases, and urine will flow back up to the ureter. If bacteria have already invaded, they will be sent to a position further upstream, causing pyelonephritis. The solution is of course not to hold your urine, and you should even develop a good habit of urinating frequently. This is also a factor that causes urinary tract infections.

7. The body's disease resistance is weakened. Such as diabetes, pregnancy, anemia, chronic liver disease, chronic kidney disease, malnutrition, tumors, congenital immunodeficiency or long-term use of immunosuppressants.

8. Overtreatment. Some people receive repeated treatments and use medications, which eventually lead to dysbiosis and fungal infection, making their condition more complicated. If the treatment is not regular, the female urethra will be short, and a large number of bacteria will be stored at the entrance and vaginal vestibule, which can easily lead to lower urinary tract infection.

9. Due to the influence of childbirth, many postmenopausal women have loose pelvic ligaments and a significant increase in residual urine in the bladder after urination.

10. Estrogen secretion decreases , and the sensitivity of the urinary tract and vaginal epithelium to pathogenic bacteria changes significantly. The disappearance of vaginal lactobacilli and other changes leading to an increase in pH is also one of the reasons.

11. Urinary tract infection can also occur during sexual intercourse, because during sexual intercourse, both men and women do not pay attention to their own hygiene, which can easily cause bacterial infection. Inhalation of the bacteria into the body can induce vaginitis, cervicitis, and urinary tract infection.
