Pregnant women whose fetus is found to have a single umbilical artery should undergo regular checkups and take nutritional supplements. 1. If a woman finds that her fetus has a single umbilical artery during a physical examination, she should have regular pregnancy checkups. If there are no other abnormalities in the fetus besides the single umbilical artery, it is enough to pay attention to the labor and delivery checkups. If the fetus has other organ developmental anomalies in addition to the single umbilical artery, further testing should be done, such as screening for chromosomal abnormalities. 2. Pregnant women with single umbilical artery should strengthen their nutrition, eat more food with high calcium and protein, and also eat more fresh fruits and vegetables rich in minerals and vitamins to ensure the healthy growth of the fetus.
