The venous system
While the arteries transport blood from the heart to the body, the veins transport the oxygen-deficient blood back to the heart – against gravity. This function is supported by the so-called muscle pump in the leg muscles and the venous valves. Like a valve, these prevent the blood from flowing back down the leg. If this system begins to fail, the blood pools in the legs. We can develop spider veins, varicose veins, venous inflammation and, in very advanced stages, venous leg ulcers, as a result.
What are venous diseases?
Veins in our legs carry blood back to our hearts. They have one-way valves that keep bleed from flowing backwards. If you have a venous disease, the valves won’t work as they should, and some blood may go back down the legs. If veins cannot operate effectively, the blood pools in the legs, and various forms of venous disease can develop.
Chronic venous diseases are widespread. The predisposition is often genetically programmed, but factors such as standing or sitting a great deal at work, obesity and lack of physical exercise can also play a role. Tired and heavy legs, pins and needles or swollen ankles can all be signs of venous insufficiency. Preventative measures can be taken by interpreting venous insufficiency changes early.
Risk factors and causes of venous diseases
Venous insufficiency is often genetic. But, other factors such as basic connective tissue laxity, pregnancies and hormonal changes can create venous disorders. Alcohol, which relaxes blood vessels, can also have an effect, as can obesity and persistent digestive problems. Habits such as standing or sitting a great deal and a lack of physical exercise are also factors in developing a venous disease. Travel can also pose risks to your vein health.
