15 Common Causes of Spider Veins You Shouldn’t Ignore

Constipation

Constipation is a common problem that people, especially women, have to deal with daily. Constipation occurs when a person has fewer than three bowel movements weekly. When fecal matter remains in the colon for too long, it dehydrates, which causes muscle spasms that can result in blood vessels in the legs. This damage can cause spider veins to form and make them more susceptible to rupture.

Spider veins are caused by back pressure from blood vessels and other factors like constipation. As a result, the veins become swollen and don’t carry enough blood back to the heart; this deprives the skin of oxygen and nutrients. In addition, constipation can be a problem in people who don’t drink enough water and eat enough fiber. This combination can cause old fecal matter to dry up in the colon and lead to dehydration. Dehydration weakens the walls of blood vessels throughout the body, including those in the legs, which can lead to spider veins forming or worsening.
