Elevated homocysteine does not normally affect pregnancy. Elevated homocysteine tends to cause high blood pressure, which increases the incidence of cardiovascular disease in patients, leading to atherosclerosis and cerebral infarction. Normal pregnant women need to take folic acid supplements before pregnancy, which not only prevents the possibility of neurological disorders in the fetus, but also reduces the effect of homocysteine. Therefore, if homocysteine is elevated, pregnancy will not be affected. In daily life, pregnant women should maintain good habits, increase physical exercise, pay attention to light diet, eat more fresh vegetables and fruits. Pregnant women are advised to consult a doctor if they experience any discomfort, and under the guidance of a professional doctor, they should take active treatment and prepare for pregnancy safely.
