What is venous insufficiency or varicose veins? Venous insufficiency is a medical condition in which the veins of the body (usually of the legs) cannot pump blood back to the heart. This causes blood to accumulate in the blood vessels and eventually enlarge (varicose veins) or dilate.
Varicose veins can be visible on the surface of the skin as large, ropey or bulging veins and are present anywhere from the groin down to the ankle. However, varicose veins can exist even if no visible signs are present. Spider veins are small red, purple or blue vessels that twist and turn and are easily visible on the surface of the skin. Spider veins are usually present near the ankles and knees.
Varicose veins are a type of vein disease. It occurs when the veins, which carry blood from the extremities back to the heart, fail. The pressure is too strong for the valves that guide the flow of blood through the vein up to the heart. When the valves fail, the blood cannot continue its journey and expands, changing its shape and size. This causes the blood to remain stagnate in the extremities and could potentially cause leg ulcers, neuropathy, and poor healing in the extremities, especially after hip or knee surgery. In severe cases, varicose veins can cause heart problems, develop into deep vein thrombosis (DVT) and/or blot clots, known as pulmonary embolisms (PE), which can be fatal. In a few words it can cause you death if you do not treat them correctly.
