Common Complications During Twin Pregnancy

Joe Rawlinson by Joe Rawlinson - April 25, 2017

Twin pregnancies can get complicated. The nature of carrying two babies can wreak havoc on poor Mom.

While there are many common complications of a twin pregnancy, don’t stress out too much about them. Modern medical care can help you overcome most of these.

Common Complications During Twin Pregnancy

Complications during twin pregnancy consist of those unique to twins plus those regularly associated with any pregnancy like high blood pressure, gestational diabetes, and anemia.

However, you may experience complications that are unique to a twin pregnancy or even those related to an identical twin pregnancy.

Read about each of these complications below:

High Blood Pressure

High blood pressure and diabetes are common during pregnancy. Your doctor will check on you at each visit to detect these early as possible.

Prevention and treatment for high blood pressure:

4 Critical Mistakes Expectant Twin Parents Make
  • Avoid salt
  • Exercise regularly
  • Check with your doctor that any medications you are currently taking are safe (for example, a decongestant for a stuffy nose can cause high blood pressure)
  • Always go to prenatal check-ups
  • Eat a diet with lots of fruits and vegetables (just like your Mom told you)

Here are some more tips for preventing hypertension (high blood pressure) during your twin pregnancy.

Gestational Diabetes

Gestational Diabetes is a form of high blood sugar that affects pregnant women. There are a few things you can do in order to reduce the chances of developing gestational diabetes.

  • Your doctor or nutritionist can provide you with a diet plan that helps keep your blood glucose within the healthy range.
  • Discuss with your doctor any foods to avoid and the timing of your meals.
  • Limit sweets and track your carbohydrate intake.
  • Increase your fiber intake.
  • Stay active. Discuss with your physician the best ways for you to remain active during your pregnancy.

Here are some more tips on preventing gestational diabetes.

Anemia

Anemia is when your blood doesn’t have enough healthy red blood cells. Because of increased blood flow during pregnancy, your iron levels drop. This is especially true in women carrying more than one fetus. Mild anemia isn’t harmful, but be mindful of taking your supplements. A major symptom of anemia is fatigue (as if you weren’t tired enough!).

Prevention and treatment: This one is very common and a little harder to prevent, your healthcare provider will most likely provide you with iron supplements.

Twin Pregnancy Complications – First Trimester

You might not even find out you are having twins until the end of the first trimester.

4 Critical Mistakes Expectant Twin Parents Make

The common complications of all pregnancies mentioned above are a risk for you here.

Miscarriages typically happen in first 12 weeks of pregnancy. There is a chance you might miscarry one or both of the babies this early in the pregnancy.

Twin Pregnancy Complications – Second Trimester

Preeclampsia during the twin pregnancy is a serious condition of high blood pressure in the mother. Watch for symptoms like a quick rise in blood pressure, protein in the urine, sudden and disproportionate weight gain, and swelling of the face and hands.

Many complications discussed here may result in bed rest for mother. Additionally, the strain of two babies on your cervix may be too much and require bed rest. Here are some things to do to more easily manage bed rest during the twin pregnancy.

Twin Pregnancy Complications- Third Trimester

You’re in the home stretch now but complications continue and additional concerns emerge around when and how your twins will be born.

Preterm labor and birth is common with twins. On average they are born around 36 weeks but can arrive much earlier than that.

Even if you are planning for a natural twin delivery, a Caesarean section (C-section) delivery may be in your future. Twin deliveries have a higher chance of c-section as both twins need to be in the right position for a vaginal birth.

Identical Twin Pregnancy Complications

One complication unique to identical twins while in the womb is Twin-to-Twin Transfusion Syndrome, or TTTS. Only monochorionic twins, or those that share a placenta, are susceptible to TTTS. This is a serious condition where one twin may get too little nutrients and fluid while the other gets too much.

Don’t Get Overwhelmed

Yes, there are a lot of common complications during twin pregnancy. However, they won’t all happen to you. In fact, you might not experience ANY of them.

Talk to your doctor about how you can prevent these. Do what you can and don’t worry about the rest. If complications arise, learn about them and take action.
