Where are vascular spiders most commonly found during pregnancy?

Vascular spiders, also known as spider angiomas, are commonly observed in pregnant individuals due to the physiological changes that occur during pregnancy, particularly the increase in blood volume and hormonal fluctuations. The facial region, as well as the arms and upper torso, is especially prone to the development of these lesions. This distribution is associated with the increased blood flow and preparation of the body for the needs of both the mother and the developing fetus.

During pregnancy, the increase in estrogen levels can lead to the dilation of small blood vessels, resulting in the characteristic appearance of vascular spiders. While other areas of the body can also experience changes, the face, arms, and upper torso are the most typical regions where these vascular lesions appear due to their proximity to surface veins and capillaries that are affected by hormonal shifts.

Understanding the location of vascular spiders can help healthcare professionals monitor the physiological changes in pregnant patients and distinguish normal changes from potential pathological conditions.
