Venous disorders refer to conditions that affect the veins, which are blood vessels responsible for returning blood to the heart. Common types include varicose veins, characterized by swollen, twisted veins, and chronic venous insufficiency, where veins struggle to send blood back to the heart. These disorders can lead to symptoms like pain, swelling, and skin changes. Risk factors for venous disorders include prolonged standing or sitting, obesity, and a family history of vein problems. Treatment options vary and may include lifestyle changes, compression stockings, or medical procedures like sclerotherapy or vein stripping to improve blood flow and alleviate symptoms.
