Women pregnant with twins or more require more frequent follow-up visits with their obstetrician, and these visits may include repeated ultrasound scans to monitor the growth and health of the fetuses [\[1\]](). ## More Frequent Follow-up Visits and Scans Multiple pregnancies require more frequent prenatal care visits. Starting from the second trimester, you may undergo ultrasound scans every 4 to 6 weeks. If a problem is suspected, your doctor may recommend special tests or more frequent ultrasound scans [\[1\]](). This intensive monitoring is essential for the early detection and effective management of any potential complications. ## Common Risks and Complications Multiple pregnancies increase the risk of several complications compared to single pregnancies. One of the most prominent is preterm birth; more than half of twins are born prematurely, and almost all pregnancies involving three or more fetuses result in preterm birth [\[1\]](). Preterm birth can lead to short-term and long-term health problems for infants, including breathing and feeding difficulties, and learning or behavioral issues may appear later in childhood or even adulthood [\[1\]](). Other complications more likely to occur in multiple pregnancies include pregnancy-induced hypertension (preeclampsia), which tends to appear earlier and be more severe [\[1\]](). There is also an increased risk of gestational diabetes, which in turn can increase the risk of preeclampsia and health issues for the newborns [\[1\]](). ## Special Nutritional Considerations and Weight Gain Women pregnant with twins or more typically require greater weight gain than those pregnant with a single child. Each additional fetus requires approximately 300 extra calories per day. For example, if you are pregnant with twins, you will need 600 extra calories per day. For pregnancies with three or more fetuses, the appropriate amount of weight gain should be discussed with your obstetrician [\[1\]](). ## Genetic Diagnostic Tests Genetic screening tests that use a maternal blood sample are less sensitive in multiple pregnancies. Screening results may be positive even if there is no issue with the fetuses [\[1\]](). Diagnostic tests such as amniocentesis and chorionic villus sampling are more difficult in multiple pregnancies because each fetus needs to be tested separately, and there is a small risk of losing one or more fetuses \[1, [2]()\]. Results from these tests may indicate that one fetus has a disorder while the others do not [\[1\]]().
