4. Pregnancy
As a pregnant woman’s body grows, it struggles to provide blood flow to the placenta. This puts pressure on the blood vessels and can lead to telangiectasia. The hormonal changes in the body during pregnancy can also contribute to the condition. Other changes in a woman’s reproductive system such as menopause or birth control pills can also cause hormonal changes that can result in telangiectasia. Since the blood vessels begin to weaken as a person gets older, women who are older when they become pregnant are more at risk for developing the condition.
The condition is also likely to be more severe in older, pregnant women or women who are beginning menopause. As the body continues to change and hormone levels go up and down, the condition may change as well. Sometimes the spider veins may appear to grow faster in more areas, and at other times, the growth or appearance may slow.
