Patient's question:
During pregnancy, it is always particularly uncomfortable, and morning sickness is also very severe. Please ask if there are any dietary considerations to pay attention to when undergoing the Down syndrome screening.Doctor's answer:
It is not advisable to eat or drink anything before undergoing a Down syndrome screening. It is recommended to go to the hospital in the morning for the screening. Down syndrome screening is a non-invasive test method for the fetus, which is economical, simple, and safe. It is performed between the 14th and 18th weeks of pregnancy. Only 2 milliliters of the pregnant woman's venous blood is required after fasting for 12 hours. The results can be obtained 2 to 3 weeks after the blood draw. If the pulmonary valve stenosis is moderate or more severe, it can be treated with percutaneous transcatheter balloon dilation of the pulmonary valve. Pay attention to increasing nutrition and undergoing regular check-ups before pregnancy.
