Pregnancy causes many changes in a woman’s body. One of these changes is the development of varicose veins, especially in the lower body regions. Although varicose veins during pregnancy may seem like a cosmetic concern, in some cases they may require treatment. So, when do these vascular changes resolve on their own, and when should you consult a doctor?
In this article, we address the causes of varicose veins during pregnancy, whether they are temporary or permanent, and common questions regarding the treatment process.

Why Do Varicose Veins Occur During Pregnancy?

Physiological changes that occur during pregnancy create a favorable environment for varicose veins:

• Increased hormone levels (especially progesterone): Loosen the walls of veins and cause vein dilation.

• Increased blood volume: The total amount of blood in the body rises, increasing pressure on veins.

• Enlargement of the uterus: The growing uterus puts pressure on pelvic veins, making blood flow from the legs more difficult.

• Genetic predisposition: Women with a family history of varicose veins are at higher risk during pregnancy.

• Weight gain and inactivity: These also increase vascular pressure.

Where Do Varicose Veins Appear During Pregnancy?

• Legs: The most common site.

• Vulva (external genital area): Pregnancy-specific vulvar varicose veins can develop.

• Rectal area: Hemorrhoids (varicose veins around the anus) are common in pregnancy.

Temporary or Permanent?

A significant portion of varicose veins appearing during pregnancy may regress within the first 3-6 months after delivery. However:

• Those who had varicose veins before pregnancy,

• Women with multiple pregnancies,

• Those with genetic predisposition,
  are at a higher risk for varicose veins becoming permanent.

When Should You See a Doctor?

It is recommended to consult a vascular specialist in the following cases:

• Pain, swelling, night cramps

• Varicose veins that grow larger and darken

• Itching, skin color changes, or skin hardening

• Discomfort or fullness sensation in vulvar varicose veins

• Suspected blood clot (sudden pain, increased warmth, redness in the leg)

Is Varicose Vein Treatment Done During Pregnancy?

Direct varicose vein treatments (such as sclerotherapy, laser, surgery) are generally not performed during pregnancy. However, to relieve symptoms and prevent progression, the following methods are recommended:

• Use of compression stockings: Helps regulate circulation and supports veins.

• Frequent position changes, elevating the legs

• Light exercises such as swimming and short walks

• Avoiding prolonged standing or sitting

• Lying on the left side: Reduces pressure of the uterus on main veins.

If varicose veins persist after delivery, modern treatment methods can be applied after proper evaluation.

What If Varicose Veins Do Not Resolve After Delivery?

If varicose veins and symptoms continue beyond 6 months after delivery, the following treatment options may be considered:

• Endovenous laser or radiofrequency ablation

• Foam sclerotherapy

• Microsclerotherapy (for spider veins)

• Surgical mini-phlebectomy (in selected cases)

Before treatment, detailed evaluation with Doppler ultrasonography should be done.

Conclusion

Varicose veins that develop during pregnancy are often temporary and may improve after delivery. However, in some cases, they can become permanent and affect quality of life. Therefore, symptoms should not be ignored, and supportive measures should be taken under medical supervision. Remember, with early diagnosis and appropriate methods, varicose veins can be effectively controlled.
