Is fetal bleeding caused by smoking?

Patient's question:

No

Doctor's answer:

Smoking during pregnancy not only affects the health of the mother 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 pass through the placenta directly into the fetus's body, slowing down embryonic development, causing deformities, miscarriages, and congenital heart disease, among other issues.
