Pregnancy Fever: Hidden Dangers for Baby
21 Mar
Summary
- High fever above 102°F in early pregnancy risks neural tube defects.
- Later trimester fevers can impact fetal brain development and coordination.
- Acetaminophen is the recommended fever reducer during pregnancy.
Fever during pregnancy poses significant risks to fetal development and requires immediate medical attention. In the first trimester, maternal core temperatures exceeding 102°F (38.9°C) can disrupt critical organogenesis, increasing the likelihood of neural tube defects such as spina bifida.
As pregnancy progresses into the second and third trimesters, elevated maternal temperatures can impact fetal brain development. Some reports suggest maternal-fetal inflammatory responses associated with fever may contribute to neurodevelopmental delays, including autism or coordination problems.
Underlying infections causing fever, like influenza or UTIs, also present risks. In later pregnancy, fever can stimulate uterine contractions, potentially leading to preterm labor.
Management focuses on quickly normalizing maternal body temperature. Acetaminophen is the preferred antipyretic medication. Non-pharmacological approaches, including increased hydration and lukewarm baths, are also advised, always with professional medical guidance to address the fever's source and ensure safety.
