Can homocysteine on the high side lead to fetal arrest?

If the pregnant woman has only slightly high homocysteine, and timely treatment, so that homocysteine values return to normal levels, it usually does not cause fetal termination. However, if the pregnant woman has a large increase in homocysteine, and no timely treatment, it may lead to a decrease in tetrahydrofolate reductase concentration, which may cause fetal termination, but also increase the risk of abortion and premature birth.

Therefore, when pregnant women are detected with high homocysteine, they should be promptly intervened under the guidance of a doctor. At the same time, they should go to the hospital regularly to check the growth and development of the fetus.
