Which complication can arise from bacterial vaginosis?

Bacterial vaginosis (BV) is an imbalance of the normal bacteria found in the vagina, and it is known to be associated with several complications during pregnancy. One of the significant complications that can arise from bacterial vaginosis is an increased risk of puerperal infections. Puerperal infections refer to infections that occur after childbirth, particularly during the postpartum period, and they can arise from various factors, including pre-existing vaginal infections like BV.

The presence of BV can create an environment that fosters bacterial growth and may lead to uterine infections or infections in the surrounding tissues after delivery. This can result in adverse outcomes for both the mother and the newborn, necessitating careful monitoring and management.

The other options, while they pertain to pregnancy complications, are not directly linked to bacterial vaginosis. For instance, increased fetal weight and gestational diabetes relate to metabolic and nutritional factors rather than infections. Preeclampsia, characterized by high blood pressure and damage to other organ systems, has different etiology involving placental factors and vascular issues, making it separate from the complications associated with bacterial vaginosis.
