Does taking folic acid cause fetal hydrocephalus?

Patient's question:

No

Doctor's answer:

Analysis of the condition: Folic acid is used to prevent neural tube defects in fetuses and does not cause hydrocephalus; there is no such side effect. Suggestions: Currently, we recommend that pregnant women take folic acid for three months to prevent neural tube defects in fetuses. If there were such a side effect, we would not advocate for it so strongly.
