Coping with symptoms in multiple pregnancy

Pregnant bellyCommon symptoms during pregnancy include nausea and vomiting, constipation, feeling full soon after eating, and heartburn. Eat as well as you can and try the suggestions below.

Talk to your LMC, or GP before you take any medications or supplements for your symptoms, or if your symptoms are severe.

This is a drink made from kiwifruit and pineapple juice. It's available in the freezer at the supermarket. Drink one to two glasses a day with a meal or with an iron supplement if you're taking one.

Being active can also help keep your bowels regular. Try to include some activity such as walking, swimming, playing with your children, or housework every day.

Feeling full soon after eating

Feeling full soon after eating (called early satiety) is common in women carrying twins or triplets. It can happen as your babies grow and push on your stomach, making it smaller. Early satiety can make it difficult for you to gain weight and get all the nutrients you and your babies need to stay healthy.

There are several tips for early satiety.

To manage heartburn, you could try:

Avoid foods and drinks that trigger heartburn. Some foods and drinks can make heartburn worse in some people. These include:
