What positions should be avoided in third trimester?

Answered by Michael Wilson

During the third trimester of pregnancy, it is important to be mindful of your sleeping positions to ensure both your comfort and the well-being of your baby. There are certain positions that should be avoided to prevent any potential complications.

Sleeping on your right side during the third trimester can put additional pressure on your liver. As the baby grows, the uterus becomes heavier and can compress the organs in the abdominal cavity. Sleeping on your right side can cause the weight of the uterus to rest on the liver, potentially leading to discomfort or even pain. It is generally recommended to avoid prolonged periods of sleeping on your right side during this stage of pregnancy.

On the other hand, sleeping flat on your back can pose a risk as well. The inferior vena cava, which is a large vein that carries deoxygenated blood from the lower body back to the heart, runs along the right side of your spine. When you lie flat on your back, the weight of the growing uterus can potentially compress the inferior vena cava and restrict blood flow. This can result in reduced blood supply to both you and your baby, leading to dizziness, shortness of breath, and even fainting. It is generally recommended to avoid sleeping on your back for extended periods, especially during the later stages of pregnancy.

Now, you might be wondering if sleeping on your stomach is a viable option. Unfortunately, as the baby grows in size, it becomes increasingly difficult, if not impossible, to comfortably lie on your stomach. The protruding abdomen makes it challenging to find a comfortable and supportive position, and it can put unnecessary pressure on the baby. Therefore, it is generally not recommended to sleep on your stomach during the third trimester.

So, what positions are recommended during the third trimester? The most commonly advised position is sleeping on your left side. This position helps to improve blood circulation and ensures optimal oxygen and nutrient flow to the placenta and your baby. It also helps to alleviate any potential pressure on the liver by allowing the uterus to rest more towards the left side of the body.

While sleeping on your left side is recommended, it’s important to note that it is not necessary to remain in this position throughout the night. It is natural for you to change positions while sleeping, and that is perfectly fine. The key is to prioritize sleeping on your left side whenever possible and avoid prolonged periods of sleeping on your back or right side.

To enhance your comfort while sleeping on your side, you can use additional support such as pillows. Placing a pillow between your legs, under your belly, or behind your back can provide extra support and help alleviate any discomfort or strain on your body.

During the third trimester, it is best to avoid sleeping on your right side due to the weight of the uterus on the liver. Sleeping on your back should also be avoided as it can potentially block the inferior vena cava and restrict blood flow. Sleeping on your stomach becomes increasingly challenging as the baby grows. The most recommended position is sleeping on your left side, which promotes better blood circulation and optimal oxygen supply to your baby. Remember to prioritize comfort and use additional support, such as pillows, to enhance your sleeping experience.
