Are twin pregnancies always considered high-risk?

Twin pregnancies generally require closer monitoring because some complications are more common. However, the level of risk varies according to the type of twins, the mother's health and how the pregnancy progresses.

Can twins be delivered vaginally?

Yes. Vaginal delivery may be possible when the babies' positions and other clinical factors are suitable. Your obstetrician will recommend the safest approach for your pregnancy.

Do twin pregnancies always result in early delivery?

No, but twin pregnancies are more likely to end before 37 weeks than singleton pregnancies. The expected timing of delivery depends on the type of twin pregnancy and whether complications develop.

Do twin pregnancies require more ultrasound scans?

Yes. Twin pregnancies generally need more frequent ultrasound scans to monitor each baby's growth and wellbeing. The schedule depends on whether the twins share a placenta and whether any complications develop.

Should I follow a special diet during a twin pregnancy?

A balanced diet with adequate protein, iron, folic acid and other essential nutrients is important. Your nutritional needs may differ during a twin pregnancy, so ask your obstetrician for personalised advice on diet, supplements and appropriate weight gain.

Twin Pregnancy - What to Expect When Carrying Two Babies

Why Do Twin Pregnancies Need Closer Monitoring?

Carrying twins places additional demands on the mother's body. Compared with a pregnancy involving one baby, twin pregnancies have a higher chance of complications, including high blood pressure, gestational diabetes, anaemia and preterm labour.

This does not mean that complications will necessarily occur. Regular antenatal visits allow the doctor to monitor the mother's health, check both babies' growth and identify concerns that may need attention.

Identical and Fraternal Twins: Why the Difference Matters

Twins may be identical or fraternal, but an important medical consideration is whether they share a placenta.

Identical twins develop from one fertilised egg that divides. Depending on when the division occurs, they may share a placenta or have separate placentas.
Fraternal twins develop from two separate eggs and usually have separate placentas.

When twins share a placenta, additional complications can occur, so the pregnancy may need more specialised ultrasound monitoring. An early ultrasound helps determine the type of twin pregnancy and guides the follow-up schedule.

What Additional Monitoring Is Needed During a Twin Pregnancy?

Twin pregnancy care usually involves more frequent check-ups than a singleton pregnancy. The exact schedule depends on whether the babies share a placenta, their growth and the mother's health.

Monitoring may include:

Ultrasound scans: To assess each baby's growth, position, amniotic fluid and, when relevant, blood flow.
Blood pressure checks: To look for signs of pregnancy-related hypertension and pre-eclampsia.
Gestational diabetes screening: To check for elevated blood sugar during pregnancy.
Blood tests: To assess issues such as anaemia when indicated.
Regular antenatal reviews: To monitor symptoms and plan the next stages of pregnancy.

Attending all scheduled appointments is important, even when the pregnancy feels normal.

What Should You Know About Delivery?

The safest delivery method depends on the babies' positions, the type of twin pregnancy, gestational age and any complications affecting the mother or babies.

Vaginal birth may be an option for some twin pregnancies, while a caesarean section may be recommended in other circumstances. Your obstetrician will discuss the available options as the pregnancy progresses.

Twin pregnancies also have a greater likelihood of preterm birth. The timing of delivery is planned according to the individual pregnancy, including whether the twins share a placenta and whether any complications develop.

How Can You Prepare for Life With Twins?

Preparing early can make the later weeks of pregnancy and the first few months after delivery easier to manage.

Keep a record of antenatal appointments and scan dates.
Follow your doctor's advice on nutrition, supplements, rest and physical activity.
Arrange practical support for the period after delivery.
Prepare essential baby supplies in advance.
Discuss signs of preterm labour and when to contact your hospital.

Contact your healthcare team promptly if you experience vaginal bleeding, fluid leakage, regular painful contractions, severe headache, visual changes or reduced fetal movement. Seek urgent assessment for severe symptoms.
