Varicose Veins

Although recent years have brought about a greater awareness of the importance of diagnosing and treating peripheral arterial disease, pathology of the venous system has received little attention. Peripheral venous disease was first mentioned in the medical literature in 500 B.C., when Hippocrates described an association between leg ulcers and varicose veins. Despite longstanding recognition, understanding of issues surrounding venous hypertension and resultant venous incompetence has lagged.

LDL Apheresis

Cholesterol is a soft and waxy substance that exists in every cell in our bodies. There are two types of cholesterol: high-density lipoprotein (HDL) which is considered “good cholesterol” and low-density lipoprotein (LDL) also known as “bad cholesterol.”  If we get too much cholesterol, large deposits of LDL collect in our arteries which increases the risk of stroke, heart attack and heart disease. This is when doctors will advise that a change is made to diet, exercise or medication.
