While visible veins may be cosmetically unappealing, their appearance is usually not a cause for concern. Activities like exercise, skin tone, exposure to the sun, tight clothing and hot temperatures can cause bulging veins. Aging, genetics, and being overweight may also contribute to veins being more noticeable. These enlarged, twisted veins appear prominently beneath the skin surface, particularly on the legs and feet. However, more uncommonly, bulging veins could be an indication of a serious health condition like blood clots. If you have visible veins with severe discolouration that cause discomfort, consult a health professional.

Understanding What Causes Bulging Veins

Veins are blood vessels responsible for the transportation of deoxygenated blood back to the heart. Bulging veins develop when blood pools in weakened or damaged veins instead of flowing efficiently back to the heart. The circulatory system relies on one-way valves within veins to prevent blood from flowing backward. When these valves malfunction, blood builds up in the affected veins, causing them to stretch and bulge outward.
