Which sleeping position can cause a miscarriage?

Published in Pregnancy Sleeping 2 mins read

While the reference material does not directly state that a specific sleeping position causes a miscarriage, it does highlight that certain sleeping positions are associated with negative pregnancy outcomes. Here's a breakdown:

Sleeping Positions and Pregnancy Risks

Physicians often recommend that pregnant women sleep on their left side. This recommendation is based on studies that suggest that certain other positions may be associated with increased risks.

Positions of Concern

  • Back sleeping: Research indicates a link between sleeping on the back and a higher risk of:
    • Stillbirth
    • Reduced fetal growth
    • Low birth weight
    • Preeclampsia (a dangerous high blood pressure disorder for the mother)
  • Right-side sleeping: Similar to back sleeping, sleeping on the right side has also been associated with the risks listed above.

These findings suggest that while sleeping on your back or right side might not directly cause a miscarriage, they are linked with a higher risk of several complications that can affect the pregnancy.


Sleeping Position Associated Risks
Back Stillbirth, reduced fetal growth, low birth weight, preeclampsia
Right Side Stillbirth, reduced fetal growth, low birth weight, preeclampsia


Recommended Sleeping Position

The left side is generally considered the safest position for sleeping during pregnancy because it improves blood flow to the uterus and the fetus.

  • Sleeping on the left side helps keep the uterus from pressing on the large blood vessels.


It is essential to consult with your healthcare provider for personalized recommendations about sleeping positions during pregnancy, as individual health circumstances can affect these guidelines.
