While anyone can experience complications during pregnancy, multiple births are considered a higher risk. This does not mean you will have problems. But your midwife or doctor will want to watch for possible complications.
Talk to your midwife or doctor straight away if you have any signs of these complications. This is especially important if you go into premature labour, have bleeding or tummy pain, dizziness, headaches or swelling.
Preterm labour and birth
The most common complication is preterm (premature) labour. This means you are more likely to go into labour before 37 weeks. Babies that are born preterm are at risk of low birth weight.
High blood pressure (gestational hypertension)
Your midwife or doctor will watch your blood pressure carefully. This is to make sure you do not develop gestational hypertension. High blood pressure during pregnancy can lead to preeclampsia.
Preeclampsia is caused by high blood pressure. It can affect both you and your unborn pēpi. It puts stress on your organs, and can cause swelling, dizziness, headaches and problems with your vision. If untreated, it can lead to more serious complications.
Preeclampsia usually resolves after birth and your blood pressure returns to normal.
Due to an increase in hormones in the placenta, you can develop diabetes during pregnancy. Having more than 1 placenta increases your resistance to insulin (the hormone made by your pancreas that helps your body use sugar for energy).
Placental abruption is when the placenta separates from the wall of your uterus before birth. It is more common if you are carrying multiple pēpi. Symptoms can include bleeding and abdominal pain, especially in your third trimester. This is an emergency situation.
Fetal growth restriction
Also known as intrauterine growth restriction, or small baby on board, this happens when 1 or more of your babies is not growing at the proper rate. This may cause preterm labour or low birth weight.
