Twin Pregnancy Weight Gain – How to Manage It

Twin Pregnancy Weight Gain - How to Manage It

If you have discovered that you are having twins, it must be an exciting time for you and your loved ones. You may have several questions about twin pregnancy at this time. One of the important questions most women expecting twins have is about how much weight they will gain in the course of the pregnancy.



Mothers-to-be may be concerned that the weight-gain in a twin pregnancy will be much more than a regular pregnancy. They may also be concerned about how to lose the excess weight after the delivery.





Why is Gaining Weight Important When You are Pregnant with Twins

Getting the right nutrition and gaining the correct quantity of weight is important for every pregnancy. However, twin pregnancies have a higher risk of premature delivery and low birth weight in babies. The babies that are born with low birth weight are at risk of developing health problems like diabetes, hypertension, and heart disease later in life. Hence, it is even more important to monitor your weight gain if you are expecting twins. This will ensure that the babies get enough nourishment in the womb for healthy growth and development.

Healthy Weight Gain for Twin Pregnancy Through Each Trimester

When you are expecting twins, you will need to gain more weight than a woman pregnant with a single baby. Doctors advise mothers who are having twins to gain between 16 to 25 kgs of weight. This is the average weight gain during a twin pregnancy. Of this, around 4.5 to 5.5 kgs will be the babies’ weight. The amniotic fluid and the extra blood produced in your body during pregnancy also contribute to the weight gain.




After the birth of the babies, mothers usually lose between 10 to 13 kg in the first 2 to 5 weeks post-delivery. That will leave the new moms with an extra weight of 5.5 to 7 kg, which is the same as what a mother might gain in a single pregnancy.

1. Weight Gain During the First Trimester

Each pregnancy is different, and not every mother will gain the exact amount of weight specified. Some women may gain more weight in one go, while others may gain weight gradually.





How Much You Will Gain

In the first trimester, moms carrying twins usually gain 2 to 3 kg of weight.

How to Manage

  • In the first trimester, moms suffer from morning sicknessnausea and vomiting making it difficult to hold down what they eat. Twin pregnancies can cause more nausea than usual as the level of pregnancy hormones in the blood is higher.
  • Some women may even lose weight due to the morning sickness. If the nausea is extreme, you may need to consult your doctor and take medication to control it.
  • Eat smaller meals at regular time intervals to ensure you are getting proper nourishment.
  • Take your prenatal vitamins without fail. Some of the vitamins may increase your morning sickness. In such a case, consult your doctor and ask for an alternative vitamin that does not aggravate your nausea.
  • Drink water and other fluids to make sure you remain adequately hydrated.

2. Weight Gain During the Second Trimester

The second trimester is usually the most comfortable period in the duration of the pregnancy. It is also the time when the mothers gain the most weight. Make sure to eat healthily and get plenty of rest during this period.




How Much You Will Gain

In the second trimester, women carrying twins should ideally gain 0.5 to 0.7 kilos per week

How to Manage

  • The morning sickness ebbs once the second trimester begins. So, women should eat healthy food to make up for any weight that they lost due to nausea in the first trimester.
  • Make sure you include healthy fats, carbohydrates in the form of whole grains, calcium, and enough protein in your diet.
  • Some examples of healthy food that will help you gain weight are lean meats like chicken and turkey, eggs, and dairy products like cheese, butter, yoghurt, and whole milk.

3. Weight Gain During the Third Trimester

The third trimester may be uncomfortable for women with twin pregnancies as they are bigger than women carrying single babies. This will make it challenging to get around and carry on with regular activities.





How Much You Will Gain

In the 3rd trimester, women carrying twins gain 0.5 to 1 kg of weight every week.

How to Manage

  • At 32 weeks, the babies will weigh around 1.8 to 2 kg each in a twin pregnancy. Moving around and carrying out daily activities will be very tough for the moms-to-be.
  • The growing babies cause the uterus to expand and put pressure on other organs. This causes problems such as a backache and acidity.
  • This is the final period of growth for the babies, so good nutrition is very important.
  • Make sure you consult your doctor about your diet and weight gain throughout the pregnancy.
