Quitting smoking before pregnancy reduces risk of low birth weight
Fertility and infertility
If you’re planning to have a baby, quitting smoking sooner rather than later will lower your chance of having a “low birth weight” baby. And the longer you smoke during pregnancy, the greater your baby’s risk. That’s the conclusion of a large study looking at the timing of smoking cessation and the risk of low birth weight or LBW (weighing less than 2.5kg).
