Sujoy Dasgupta: How Smoking Increases Pregnancy Complications

Sujoy Dasgupta, Consultant, Reproductive Medicine at Genome Fertility Centre, shared a post on LinkedIn:

“How Smoking Increases Pregnancy Complications

Smoking does not only affect the mother’s health—it also has direct harmful effects on the developing baby. Nicotine, carbon monoxide, and other toxic chemicals present in cigarette smoke can easily cross the placenta and reach the fetus.

1. Reduced Oxygen Supply to the Baby
Carbon monoxide reduces the blood’s ability to carry oxygen. As a result, the baby receives less oxygen, which can affect growth and brain development.

2. Increased Risk of Low Birth Weight
Smoking slows fetal growth, increasing the likelihood of delivering a baby with low birth weight.

3. Higher Risk of Preterm Delivery
Smoking increases the risk of giving birth before the pregnancy reaches full term. Premature babies are more likely to face breathing difficulties, infections, and other health complications.

4. Placental Problems
Smoking can increase the risk of placental abruption (where the placenta separates from the uterus before delivery) and placenta previa (where the placenta lies abnormally low in the uterus). Both conditions can be dangerous for the mother and the baby.

5. Increased Risk of Miscarriage and Stillbirth
Women who smoke during pregnancy have a higher risk of miscarriage and stillbirth.

6. Increased Risk of Ectopic Pregnancy
Smoking can interfere with the normal function and movement of the fallopian tubes. As a result, a fertilized egg may become implanted in the tube instead of reaching the uterus. Ectopic pregnancy is a medical emergency and can be life-threatening if not diagnosed and treated promptly.

7. Problems After Birth
Babies exposed to cigarette smoke during pregnancy are at higher risk of breathing problems, sudden infant death syndrome (SIDS), and long-term respiratory illnesses.

8. Passive Smoking Is Harmful Too
Even if a pregnant woman does not smoke herself, exposure to secondhand smoke can cause similar harmful effects on both mother and baby.
