People who are overweight have an increased risk of varicose veins.
What are varicose veins?
An example of varicose veins in the leg.
Varicose veins are large, swollen veins that often appear on the legs and feet. They happen when the valves in the veins do not work properly, so the blood does not flow effectively.
The veins rarely need treatment for health reasons, but if swelling, aching, and painful legs result, and if there is considerable discomfort, treatment is available.
There are various options, including some home remedies.
In severe cases, a varicose vein may rupture, or develop into varicose ulcers on the skin. These will require treatment.
Treatment
If the patient has no symptoms or discomfort and is not bothered by the sight of the varicose veins, treatment might not be necessary. However, if there are symptoms, treatment may be required to reduce pain or discomfort, address complications, such as leg ulcers, skin discoloration, or swelling.
Some patients may also want treatment for cosmetic reasons – they want to get rid of the “ugly” varicose veins.
Symptoms
In the majority of cases, there is no pain, but signs and symptoms of varicose veins may include:
veins look twisted, swollen, and lumpy (bulging)
the veins are blue or dark purple
Some patients may also experience:
aching legs
legs feel heavy, especially after exercise or at night
a minor injury to the affected area may result in longer bleeding than normal
lipodermatosclerosis – fat under the skin just above the ankle can become hard, resulting in the skin shrinking
swollen ankles
telangiectasia in the affected leg (spider veins)
there may be a shiny skin discoloration near the varicose veins, usually brownish or blue in color
venous eczema (stasis dermatitis) – skin in the affected area is red, dry, and itchy
when suddenly standing up, some individuals experience leg cramps
a high percentage of people with varicose veins also have restless legs syndrome
atrophie blanche – irregular whitish patches that look like scars appear at the ankles
Causes
The veins have one-way valves so that the blood can travel in only one direction. If the walls of the vein become stretched and less flexible (elastic), the valves may get weaker. A weakened valve can allow blood to leak backward and eventually flow in the opposite direction.
The veins furthest from the heart are most often affected, such as those in the legs. This is because gravity makes it harder for blood to flow back to the heart. Any condition that puts pressure on the abdomen has the potential to cause varicose veins; for instance, pregnancy, constipation and, in rare cases, tumors.
risk factors are menopause pregnancy
being aged over 50

Gender: Varicose veins affect women more often than males. It may be that female hormones relax veins. If so, taking birth control pills or hormone therapy (HT) might contribute.
Genetics: Varicose veins often run in families.
Obesity: Being overweight or obese increases the risk of varicose veins.
Age: The risk increases with age, due to wear and tear on vein valves.
Some jobs: An individual who has to spend a long time standing at work may have a higher chance of varicose veins.
