It’s a no-brainer that smoking and pregnancy are two poles apart and that smoking is harmful for the baby — everyone knows that.
But the real questions most mothers have are:
“What if I had a drink before I even knew I was pregnant?”
“Is one cigarette enough to cause harm?”
“Will my baby still be okay?”
This blog answers those questions clearly and without any judgement, so you know exactly what to do next.
Does Smoking Affect Pregnancy?
When a pregnant mother smokes, harmful chemicals such as nicotine and carbon monoxide present in the cigarette enter her bloodstream, pass through the placenta, and reach the baby.
This results in reduced oxygen supply to the baby which impacts the baby’s growth and development.
Effects of Smoking on Pregnancy
Research shows that smoking during pregnancy increases the risk of miscarriage, preterm birth, low birth weight, and stillbirth.
Smoking during pregnancy can cause issues such as:
- Miscarriage
- Preterm birth
- Low birth weight
- Stillbirth
Light Smoking During Pregnancy – Is It Safe?
No. Smoking and pregnancy don’t go hand in hand.No matter how light you smoke, it isn’t safe for the baby. There’s no “safe limit.” Each puff sends toxins to your baby.
A research paper found that women who smoke during pregnancy have about a 47% increased risk of stillbirth.
Is there a safe amount of smoking or second-hand smoke exposure?
No. There is no safe level of smoking or second-hand smoke exposure during pregnancy. Smoking and pregnancy is a combination that increases the chances of complications like low birth weight and preterm delivery.
Even brief exposure can increase the risk of health complications for the baby.
How Soon Does Quitting Reduce Risks to the Fetus?
Ideally, it is suggested that you quit smoking at least 3 months before planning for pregnancy. But if you have had an unplanned pregnancy, then it is suggested to stop smoking immediately and visit your gynecologist to evaluate your baby’s health.
Long-Term Effects of Smoking During Pregnancy on the Baby
The effects of maternal smoking last longer than you might imagine. Children born to smoking mothers have higher chances of developing health issues such as asthma, ear infections, behavioural issues, attention problems, and slow growth.
Risks of E-Cigarettes and Vaping While Pregnant
Pregnant women smoking E-cigarettes is as harmful as smoking a regular cigarette.
Vaping or e-cigarettes still release nicotine and other harmful chemicals to the baby. Therefore, it is strongly recommended to avoid all forms of smoking during pregnancy.
