In short
Varicose veins are swollen, twisted veins visible just under the skin that usually occur in the legs but can also form in other parts of the body. If the one-way valves that help keep blood flowing toward the heart are weak or damaged, blood can back up and pool, causing the veins to swell. Individuals are more at risk if they are older, are female, have obesity, do not exercise, have a family history of varicose veins, or are pregnant.

Description
Varicose veins are swollen, twisted veins that you can see just under the skin. They usually occur in the legs, but also can form in other parts of the body. Hemorrhoids are a type of varicose vein.
Your veins have one-way valves that help keep blood flowing toward your heart. If the valves are weak or damaged, blood can back up and pool in your veins. This causes the veins to swell, which can lead to varicose veins.
Varicose veins are very common. You are more at risk if you are older, are female, have obesity, don't exercise, or have a family history of varicose veins. They can also be more common in pregnancy.
Doctors often diagnose varicose veins from a physical exam. Sometimes you may need additional tests.
Exercising, losing weight, elevating your legs when resting, and not crossing them when sitting can help keep varicose veins from getting worse. Wearing loose clothing and avoiding long periods of standing can also help. If varicose veins are painful or you don't like the way they look, your doctor may recommend procedures to remove them.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
