Varicose veins

Overview

Varicose veins are swollen, twisted veins under the skin, usually on the legs. They're common and are not usually serious, but there are treatments that can help if they're causing problems.

Symptoms

Swollen/bulging blue/purple veins in legs; aching; heavy legs.

Causes

Varicose veins happen when the valves that control the flow of blood in your vein do not work properly. This causes blood to build up and put pressure on the vein, which makes it swell and twist. Varicose veins are very common and anyone can get them, but it's more likely to happen if you: are a womanare olderare overweightare pregnantspend a lot of time standing or sittinghave other family members with varicose veinshave haddeep vein thrombosis (DVT)
