What maternal health issue can result from untreated urinary tract infection during pregnancy?

Untreated urinary tract infections (UTIs) during pregnancy can lead to a variety of complications, with preterm labor being one of the most significant risks. A UTI in pregnant individuals can progress to pyelonephritis, a severe kidney infection that can cause maternal fever, dehydration, and systemic infection. These complications can stimulate uterine contractions, potentially resulting in preterm labor.

Additionally, the inflammatory response associated with a UTI can also increase the risk of contractions in the uterus. The physiological changes during pregnancy make the urinary tract more susceptible to infections, and if these infections are not appropriately managed, the risk of delivering prematurely increases notably. Addressing UTIs promptly is crucial to protect both maternal and fetal health, thereby preventing potential outcomes like preterm birth.
