Which lifestyle practice should be avoided to ensure a healthy pregnancy?

Smoking should be avoided during pregnancy because it is associated with numerous adverse effects on both the mother and the developing fetus. Smoking can lead to complications such as preterm birth, low birth weight, placental abruption, and increased risk of congenital abnormalities. Additionally, exposure to tobacco smoke increases the likelihood of Sudden Infant Death Syndrome (SIDS) and can negatively affect the baby's lung development and overall health.

In contrast, regular exercise, a balanced diet, and taking prenatal vitamins are all beneficial practices during pregnancy. Regular exercise can improve overall physical health, aid in managing weight gain, and reduce the risk of gestational diabetes and hypertension. A balanced diet ensures that both the mother and baby receive essential nutrients needed for healthy development. Taking prenatal vitamins is crucial as they provide necessary folic acid and other vitamins that can help prevent neural tube defects and support fetal growth. Therefore, avoiding smoking is essential for promoting a healthy pregnancy and ensuring the well-being of both the mother and child.
