hi and welcome to HCM Yes, definitely smoking affects your baby in the womb, Smoking during pregnancy affects you and your baby s health before, during, and after your baby is born. The nicotine (the addictive substance in cigarettes), carbon monoxide, and numerous other poisons you inhale from a cigarette are carried through your bloodstream and go directly to your baby. Smoking while pregnant will: Lower the amount of oxygen available to you and your growing baby. Increase your baby s heart rate. Increase the chances of miscarriage and stillbirth. Increase the risk that your baby is born prematurely and/or born with low birth weight. Increase your baby s risk of developing respiratory (lung) problems. Here are some tips that may help you kick the habit: Hide your matches, lighters, and ashtrays. Designate your home a non-smoking area. Ask people who smoke not to smoke around you. Change your habits connected with smoking. If you smoked while driving or when feeling stressed, try other activities to replace smoking. Keep mints or gum (preferably sugarless) on hand for those times when you get the urge to smoke. Stay active to keep your mind off smoking and help relieve tension: take a walk, exercise, read a book, or try a new a hobby. If nothing helps in quitting the habit, please consult your doctor for help Regards Dr santosh
