UTIs During Pregnancy
Ten percent of expectant moms will get a UTI at some point during pregnancy. However, these infections sometimes go untreated because women don't recognize the symptoms, or there are none; 2 to 7 percent of UTIs among pregnant women are asymptomatic. And therein lies a serious problem: If an expectant mother doesn't know she has a UTI, she won't seek treatment. If left untreated, about 30 to 40 percent of asymptomatic UTIs develop into a kidney infection in the third trimester, putting a woman at risk for preterm labor and a low birth weight baby.
There's no need to panic; most ob-gyns test a woman's urine on her first prenatal visit, to screen for asymptomatic bacteria and to determine whether she has any risk factors that indicate she'll need regular urine cultures for asymptomatic UTIs, such as diabetes.
