Is fetal bleeding caused by smoking?

Patient's question:

No

Doctor's answer:

Pregnant women smoking not only affects their own health but also directly impacts the development of the fetus. Tobacco contains more than 20 toxic substances, among which nicotine is the most toxic. It can enter the fetus's body directly through the placenta, slowing down embryonic development, causing deformities, miscarriages, and congenital heart diseases, among other conditions.
