Urinary Tract Infections In Pregnancy

Urinary tract infections in pregnancy are relatively common. Because the pregnancy hormone progesterone causes the urinary tract to dilate and bacteria can penetrate more easily.

Even pregnant women then have to be treated with antibiotics. Otherwise serious complications can develop during pregnancy – not least because an untreated urinary tract infection (cystitis, bladder infection) can also develop into a kidney infection.

In order to keep the risk for mother and child low, the urine of pregnant women is also regularly tested for bacteria during preventive medical check-ups. And the mother-to-be can also do something through her behavior to ensure that a urinary tract infection does not occur during pregnancy.

Why are urinary tract infections common during pregnancy?

The fact that urinary tract infections occur relatively frequently during pregnancy is due to the hormonal situation of the mother-to-be: the pregnancy hormone progesterone makes all muscles loose and soft so that the womb (uterus) can expand properly. However, progesterone also has a relaxing effect on the ureters, which dilate as a result. It is therefore easier for pathogens to ascend into the bladder than usual during pregnancy. Women are more likely to suffer from cystitis than men anyway because they have a shorter urethra.

In addition, the growing uterus puts pressure on the ureter: the urine can flow out much more slowly, so that bacteria may have enough time to settle in the ureter and cause inflammation there.

How do I know I’m affected?

Typical symptoms of a urinary tract infections in pregnancy are:

If such symptoms occur in pregnant women, you should see your gynecologist as soon as possible! With a simple urine test, he can determine whether there are bacteria in the urine. This test is also carried out regularly during check-ups in order to detect urinary tract infections at an early stage.

Other diagnostic methods may also be used, as are also usual with urinary tract infections, such as a urine culture, to identify the exact pathogen. If there is a bladder infection during pregnancy, the treatment of choice – as usual – is treatment with antibiotics.
