What is one harmful effect of smoking during pregnancy?

Smoking during pregnancy has well-documented negative effects on fetal development, with one significant concern being the higher chance of preterm birth. When a pregnant individual smokes, the chemicals in cigarettes can restrict blood flow to the placenta, leading to complications that may precipitate early labor. Preterm birth is defined as giving birth before 37 weeks of gestation, and babies born preterm are at increased risk for a range of health issues, including respiratory problems, feeding difficulties, and longer hospital stays after birth.

Additionally, the toxic substances in cigarette smoke can impair fetal growth and development, contributing to further complications such as low birth weight. However, the specific linkage to preterm birth highlights the immediate danger that smoking poses to the duration of a pregnancy, making it a critical focus for maternal health interventions. Ultimately, understanding these risks is vital for ensuring healthier outcomes for both mothers and their babies.
