What are varicose veins?
Varicose veins are enlarged veins that develop when blood flow from the legs back to the heart is impaired. In healthy veins, small valves ensure that blood flows in one direction. When these valves function less effectively, blood can accumulate in the legs. This puts extra pressure on the vein walls and can cause veins to become visibly wider.
Varicose veins primarily occur in the legs and can range from small visible veins to clearly thickened and tortuous veins.
What causes varicose veins?
For many people, predisposition plays a major role. If varicose veins run in the family, there is a greater chance that the vein walls or valves are weaker. Additionally, prolonged standing, prolonged sitting, pregnancy, age, and heat can contribute to the development of symptoms.
Athletes can also experience symptoms. During prolonged exertion of the legs, such as running, walking, or long periods of standing at work, the legs can feel heavy or tired more quickly when the circulatory system is under extra strain.
What are the symptoms of varicose veins?
The initial symptoms are often not immediately visible varicose veins, but rather a sensation in the legs. Many people experience heavy or tired legs, a pulling sensation in the calves, or slight swelling around the ankles. Symptoms can worsen, especially at the end of the day or after prolonged exertion.
Additionally, restless legs, itching, a tense feeling, or visible blue and purple veins can develop. Warm weather or prolonged sitting often causes symptoms to be more pronounced for many people.
