Vaginal infections during pregnancy can also increase the risk of preterm delivery, especially if left untreated. The types of infections most commonly associated with preterm birth include bacterial vaginosis (BV), yeast infections, and sexually transmitted infections (STIs). Here’s how these infections may contribute to preterm delivery: 1. Bacterial Vaginosis (BV): Risk of Preterm Birth: BV is a common vaginal infection caused by an imbalance of normal vaginal bacteria. Studies have shown that BV increases the risk of preterm labor and delivery, particularly if the infection is untreated. Mechanism: BV can lead to inflammation in the cervix and increase the risk of infections ascending to the uterus, which may trigger early labor. 2. Yeast Infections (Candidiasis): Impact on Pregnancy: While yeast infections (often caused by Candida species) are more common during pregnancy due to hormonal changes, they are generally not associated with preterm birth. However, if the infection is severe or recurrent, it may increase the risk of complications. Treatment: Yeast infections are typically treatable with antifungal medications that are safe during pregnancy. 3. Sexually Transmitted Infections (STIs): STIs and Preterm Birth: Infections such as chlamydia, gonorrhea, syphilis, and herpes can increase the risk of preterm labor and birth if left untreated. These infections can cause inflammation, pelvic infections, and, in some cases, direct harm to the fetus. Chlamydia and Gonorrhea: Both are linked to an increased risk of preterm birth, low birth weight, and even miscarriage if untreated. Herpes: Genital herpes can lead to complications if an active outbreak occurs near the time of delivery, potentially leading to a cesarean delivery. If a woman has an active infection during labor, it may also increase the risk of transmitting the virus to the baby. 4. Cervicovaginal Infections: Some infections may trigger the release of inflammatory mediators, which can cause premature rupture of membranes (PROM), a key risk factor for preterm birth. These infections may also contribute to uterine contractions that lead to preterm labor. Preventing Vaginal Infections and Reducing the Risk of Preterm Birth: Routine Screening: Pregnant women should be screened for infections like BV, STIs, and yeast infections, especially in the first trimester. Prompt Treatment: Early diagnosis and appropriate treatment with antibiotics, antifungals, or antivirals are important to reduce the risk of complications like preterm birth. Good Hygiene: Maintaining proper genital hygiene, avoiding douching, and wearing loose, breathable clothing can help prevent infections. Safe Sexual Practices: Using barrier methods like condoms and ensuring that any STIs are treated promptly can reduce the risk of infection during pregnancy.
