Visible veins: when are they harmless and when do they signal a health problem?

Bulging veins—especially on the hands, forearms, or legs—are often dismissed as a harmless sign of age, low body fat, or active exercise. But sometimes, suddenly noticeable veins can indicate underlying health conditions that shouldn’t be ignored. Here are five conditions that could be behind “bulging” or highly visible veins.

1. Chronic venous insufficiency (CVI)

In CVD, the valves in the veins weaken or fail, making it difficult for blood to return to the heart. The result is blood pooling in the extremities (most often the legs) and visible, enlarged veins.

Symptoms:

rope-like, protruding veins

feeling of heaviness, swelling, or pain in the legs

darkening of the skin or ulcers around the ankles

The condition is more common in older people and in occupations that involve prolonged standing or sitting. Without treatment, it can lead to ulcers or thrombosis.
