Varicose Veins Basics
For helping circulation of oxygen-rich blood between the lungs and all parts of the body - human arteries have thick layers of muscle or elastic tissue. When pushing blood back to the heart, veins mainly rely on surrounding muscles and network of one-way valves. Therefore, as blood flows through a vein - the cup-alike valves alternately open for allowing blood through, and close to prevent backflow then.
How does it work in the case of varicose veins? The valves do not work properly - allowing blood to pool in the vein and making it difficult for the muscles to push the blood up. As result, instead of flowing from one valve to the next one, the blood continues to pool in the vein. It increases both - venous pressure and the likelihood of congestion while causing the vein to bulge and twist. Moreover, superficial veins receive less muscle support than deep veins. Therefore, they are more likely to become varicose.
The most conditions, which add an excessive pressure on the legs and/or abdomen, may create varicose veins. Among the most common pressure inducers are pregnancy, obesity, standing still during long time and so on. In more rare cases, chronic constipation and tumors also cause varicose veins conditions.
