varicosis /ver′ikō″sis/ [L, varix + Gk, osis, condition] , a common condition characterized by one or more tortuous, abnormally dilated vessels, usually in the legs or the lower trunk. It most often occurs in persons between 30 and 60 years of age. Varicosis may be caused by congenital defects of the valves or walls of the veins or by congestion and increased intraluminal pressure resulting from prolonged standing, poor posture, pregnancy, abdominal tumor, or chronic systemic disease. Symptoms include pain and muscle cramps with a feeling of fullness and heaviness in the legs. Dilation of superficial veins is often evident before the condition produces discomfort.
