Varicose veins are swollen, twisted, blue-in-colour blood vessels under the skin. They most commonly occur in the legs and feet (Better Health Channel 2020).
Veins have one-way valves inside of them that open and close to keep blood flowing towards the heart. When weakened or damaged, valves or walls in the vein cause blood to pool or flow backward (reflux). Varicose veins occur when these veins grow larger and become distorted due to blood pooling (NHLBI 2022; Better Health Channel 2020).
Note that while they mainly appear in the legs, varicose veins can also occur in the:

Closely associated with varicose veins are ‘spider veins’, which occur when blood that collects in varicose veins leaks into smaller blood vessels (capillaries) and enlarges them. Spider veins are smaller and closer to the surface of the skin. They are often found on the face or legs (Healthdirect 2022; Better Health Channel 2020).
The exact reason why varicose veins occur in certain people is unknown. However, there is considerable evidence to support the claim that genetic links and a past history of deep vein thrombosis (a blood clot that occurs in a deep vein) are predictors for this condition (Wright & Fitridge 2013).
The veins in the legs are further away from the heart. Therefore, blood is working against gravity for a long distance, making it more difficult for blood to flow upwards (OASH 2021).
Women are twice as likely to get varicose veins as men. It’s thought that female hormones might cause the veins to dilate. If this is the case, birth control pills or hormone therapy could contribute to the likelihood of developing varicose veins (Brazier & Biggers 2022).

Any situation where blood flow is restricted or undermined is cause for concern. While most varicose veins cause no complications, potential issues include:
(Brazier & Biggers 2022; Healthdirect 2022)
Note that bleeding from varicose veins is considered a medical emergency (NHLBI 2022).
To diagnose varicose veins, a general practitioner (GP) will perform a physical examination and request the following information:
(NHLBI 2022)
A GP might assess the health of the leg veins using ultrasound or other imaging tests such as an x-ray or computed tomography (CT) scan (NHLBI 2022).
Treatment options range from conservative to surgical approaches. Varicose veins are a progressive disease, so they will steadily worsen. Complications develop in a relatively small number of cases and may prompt the patient to seek medical care (Wright & Fitridge 2013).
Age, general health condition and symptomatology will be deciding factors for the route of treatment for people living with varicose veins (NHLBI 2022).
Treatment options include:
(Healthdirect 2022; NHLBI 2022)
The aim of treatment is to relieve symptoms, improve appearanc, and prevent complications such as serious skin ulcers or sores, DVT, skin colour changes and bleeding (NHLBI 2022).
While it is not entirely within a person’s control to prevent varicose veins, the following may help to reduce the risk of developing them or developing more:
