Pregnancy is a time of many physical changes, and some of them may be unexpected. One such change that may occur is the development of varicose veins. These enlarged, twisted veins are often blue or purple in color and are commonly found on the legs. While they may not always cause discomfort, they can raise questions for expectant mothers.
What Are Varicose Veins?
Varicose veins develop when veins become enlarged and overfilled with blood. Veins have a series of valves that help to regulate the flow of blood back to the heart. When these valves weaken or are unable to function properly, blood can pool in the veins, leading to swelling and a change in their appearance.
Several factors may make varicose veins more noticeable during pregnancy. Hormonal changes can relax vein walls, and the growing uterus may put additional pressure on veins in the lower body. These veins can also show up in other areas, such as around the pelvis, and are sometimes referred to as vulvar varicosities.
Why Are They More Common During Pregnancy?
The physical and hormonal changes that occur during pregnancy contribute to the increased likelihood of enlarged veins. These may include:
- Hormonal Shifts: During pregnancy, higher levels of progesterone relax the walls of blood vessels. This may reduce the strength of valves within the veins, leading to blood pooling.
- Increased Blood Volume: Pregnancy increases overall blood volume to support the developing baby. While this is necessary for fetal growth, it can place extra strain on the venous system.
- Pressure from the Uterus: The growing uterus can compress the veins in the pelvis, making it harder for blood to circulate back up to the heart. This can result in blood pooling in the veins of the legs.
Managing Vein Health During Pregnancy

There are several ways to manage the appearance and discomfort of varicose veins during pregnancy. Adopting certain habits can help reduce the symptoms and may prevent further vein-related issues. These may include:
- Elevating Your Legs: Elevating your legs when resting helps improve circulation and reduce swelling. Aim to elevate them to or above the level of your heart whenever possible.
- Staying Active: Moderate physical activity, such as walking, can promote healthy blood flow and prevents blood from pooling in the veins.
- Wearing Compression Stockings: Compression stockings are designed to apply pressure at specific points on your legs to encourage proper blood flow.
- Avoiding Long Periods of Standing or Sitting: Alternating between sitting and standing throughout the day helps to minimize pressure on the veins.
- Sleeping on Your Left Side: Lying on your left side can reduce pressure on the large vein in your abdomen, improving circulation to the lower body.
Do Varicose Veins Need Medical Attention?
Varicose veins may be a temporary and manageable part of pregnancy for many. They often diminish or resolve entirely after childbirth. Seek medical advice if you experience sudden pain, intense swelling, redness around a vein, or if the skin near the vein becomes warm to the touch. These symptoms may indicate the need for prompt evaluation.
