Varicose veins are twisted swollen veins commonly found in the legs. They can be easily identified through their symptoms which include itching of veins, breeding of the swollen veins, hardening and heavy feeling in the legs, and elevated pain after standing or sitting. Seek advice and treatment from a Vascular Veins Specialist if you have any of these symptoms.
Varicose veins occur if the veins start to malfunction. Veins carry deoxygenated blood to the heart. They usually have one-way valves which prevent backflow of this blood. If the valves are not functioning, blood starts accumulating in the veins making them swollen. This is mostly common in the legs since more energy to pump blood against gravity is required. Varicose veins are associated with the following causes:
- Pregnancy. It leads to increase in volume of blood in the body, but reduce the circulation of blood from the legs.
- Age. Veins lose their elasticity as people grow old.
- Standing or sitting for a long time
Some factors which may increase the risk of having varicose veins include:
- Sex. Women are more vulnerable to varicose veins development.
- Obesity. People who have overweight are more vulnerable.
- Older people are more likely to have varicose veins.
- Family history. If your family has a history of this condition, you may also have it.
