Twin Pregnancy - A Guide to Dichorionic/Diamniotic Twins

When a woman is pregnant with twins, there are different types of twin pregnancies. One of the most common types is known as dichorionic/diamniotic twins. This means that the twins have their own separate placenta and amniotic sac. Here's what you need to know about this type of twin pregnancy:

  1. What is a dichorionic/diamniotic twin pregnancy?
  2. In a dichorionic/diamniotic twin pregnancy, each twin has their own placenta and amniotic sac. This occurs when the fertilized egg splits early in development, usually within the first three days. The twins will be fraternal (non-identical) twins.

  3. What are the risks associated with this type of twin pregnancy?
  4. Like any pregnancy, there are risks involved with carrying dichorionic/diamniotic twins. These risks include:

    • Preterm labor and birth
    • Growth problems with one or both twins
    • Preeclampsia (high blood pressure and organ damage)
    • Twin-to-twin transfusion syndrome (TTTS)
  5. What are the symptoms of dichorionic/diamniotic twin pregnancy?
  6. The symptoms of this type of twin pregnancy are similar to a singleton pregnancy, but may be more severe. Symptoms include:

    • Increased fatigue
    • Nausea and vomiting
    • Increased appetite
    • Swollen feet and ankles
    • Heartburn and indigestion
  7. How is a dichorionic/diamniotic twin pregnancy monitored?
  8. During a dichorionic/diamniotic twin pregnancy, the mother will have more frequent prenatal appointments and ultrasounds to monitor the growth and health of both twins. The doctor will also check the fluid levels in each twin's amniotic sac.

  9. What are the delivery options for dichorionic/diamniotic twins?
  10. Most dichorionic/diamniotic twin pregnancies will result in a vaginal delivery, but a cesarean section may be necessary if there are complications or if one or both twins are in distress. The doctor will discuss delivery options with the mother and make a plan based on the health of both twins.
