What is a common risk of using aspirin during pregnancy?

Aspirin is a non-steroidal anti-inflammatory drug (NSAID) commonly used for pain relief, but its use during pregnancy has several considerations due to potential risks. One significant risk associated with aspirin use in pregnant women is the potential for kernicterus in jaundiced neonates. Kernicterus is a form of brain damage that can occur in newborns with severe jaundice, primarily due to unconjugated bilirubin crossing the blood-brain barrier.

When a mother takes aspirin, especially in the latter stages of pregnancy, it can affect platelet function and the metabolism of bilirubin, which may lead to increased jaundice in the newborn. This is especially crucial in cases where the infant is already predisposed to jaundice. Monitoring and managing bilirubin levels becomes essential after delivery to prevent kernicterus from developing in the neonate.

In contrast, low blood pressure, increased ovulation, and a higher likelihood of premature rupture of membranes are not recognized as common risks associated specifically with aspirin use during pregnancy. These factors may arise from other conditions or medications but are not directly linked to the use of aspirin in pregnant women. Thus, the chosen answer accurately highlights a significant concern regarding the impact of aspirin on newborn health.
