The Dangers of Smoking During Pregnancy

Before delving into the complexities, let’s confront the perilous cocktail of toxins concealed within cigarettes: nicotine, carbon monoxide, and tar. These culprits spell trouble for both mother and unborn child, demanding that informed decisions be made during pregnancy.

Getting Pregnant

Smoking and fertility share a complex relationship. For couples yearning to conceive, quitting smoking should top the list. Why? American Society for Reproductive Medicine verified, that both male and female smokers have a double risk of fertility complications compared to non-smoking couples.

Even secondhand smoke poses an equivalent threat to the developing fetus. Pregnant women exposed to secondhand smoke are at an elevated risk of complications.

Miscarriage and Stillbirth

The sorrow of losing a pregnancy knows no bounds, whether it occurs early on or later in gestation. Smoking substantially raises the odds of such heart-wrenching experiences. According to the U.S. Centers for Disease Control and Prevention (CDC), smoking during pregnancy may lead to early miscarriages and stillbirths. The treacherous chemicals in cigarettes are often implicated in these tragic scenarios.

Complications stemming from smoking can also inflict harm on the placenta and fetal development, potentially culminating in miscarriages or stillbirths.

Ectopic Pregnancy

Nicotine, a detrimental element found in cigarettes, has the potential to trigger contractions within the fallopian tubes, significantly elevating the chances of ectopic pregnancies. In this grave circumstance, the fertilized egg implants itself outside the uterus, often within the fallopian tube or the abdominal cavity. This is an extremely perilous condition that requires immediate medical intervention.

Placental Abruption

The placenta often hailed as the “lifeline” of pregnancy, supplies vital nutrients and oxygen to the growing fetus. Smoking can lead to complications with the placenta, including placental abruption. Such a situation happens when the placenta detaches prematurely from the uterine wall before childbirth. That causes heavy bleeding and is dangerous both for the mother and the baby. Reattachment is impossible and prompt medical help is needed.

Placenta Previa

Placenta Previa can occur as a result if you smoke being pregnant. The placenta is usually located in the upper part of the uterus, ensuring an unobstructed cervix for delivery. However, placenta previa emerges when the placenta remains anchored in the lower uterine region, partially or fully obstructing the cervix. This can even result in placental tears, excessive bleeding, and fetal deprivation of vital nutrients and oxygen.

Preterm Birth

The CDC emphasizes that smoking during pregnancy escalates the probability of preterm birth, where the baby arrives earlier than expected. This ushers in an array of health risks for the newborn, encompassing visual and hearing impairments, mental disabilities, learning and behavioral challenges, and even life-threatening complications.

Low Birth Weight

Smoking might cause a low birth weight. It could result in not just the birth of a smaller baby but also various health problems and handicaps. These can encompass delays in development, cerebral palsy, and issues with hearing or sight. Not so often, but it can also tragically culminate in neonatal mortality. In any case, refraining from smoking during pregnancy decreases the likelihood of the baby being born with a low birth weight. This information is substantiated by research conducted by the American Cancer Society.

Birth Defects

The perils of smoking during pregnancy stretch to an escalated risk of birth defects, with congenital heart abnormalities and structural heart issues topping the list. Additionally, cleft lip and cleft palate have been associated with maternal smoking during pregnancy.

Resources to Help You Quit

Quitting smoking is undeniably challenging, but a wealth of resources exists to bolster expectant mothers in their quest for a smoke-free life. Smoking cessation programs, counseling services, and smartphone apps are valuable aids. Simultaneously, garnering support from friends, family, and healthcare providers is pivotal to surmounting the hurdles of quitting smoking during pregnancy.
