evidence: A pregnancy is considered high risk when the mother and/or the fetus or baby have medical conditions or other health issues that increase the risk of becoming ill before, during, or after delivery. High-risk pregnancies include those in which there is a potential risk to the health of the mother and/or the fetus or baby. Risks can result from various factors such as chronic disease, having more than one fetus (multiple gestation), previous pregnancy complications, or complications either related or unrelated to the pregnancy that arise during a pregnancy. [...] High-risk pregnancies must be closely monitored and involve specialized care, often including obstetricians and a hospital that specialize in high-risk pregnancies.
