Venous ulcers, which are open wounds that develop close to the ankles and heal slowly because of inadequate circulation, can result from varicose veins if left untreated.
Blood clots are another major consequence that can progress to pulmonary embolism, superficial thrombophlebitis, or deep vein thrombosis.
Although it is not always possible to avoid varicose veins, you can lower your risk by maintaining an active lifestyle, losing weight, stopping smoking, and dressing loosely, particularly around the waist.
