Vascular disorders comprise some of the most common disorders in humans. Usually symptoms of vascular disorders are not seen until the condition reaches a point where it is considered serious. Several vascular disorders are discussed below:
a. Arteriosclerosis. A loss of elasticity or hardening of the arterial walls characterizes arteriosclerosis. The result is a decrease in the ability of these arteries to change their diameter. A complication that usually accompanies arteriosclerosis is atherosclerosis. Atherosclerosis is a condition in which lipid (fat) deposits form on the inside of the arteries causing a decrease in the flow of blood through the arteries. Both these conditions show a higher incidence in diabetics and in overweight individuals. Surgery and antihyperlipidemic drugs are used to treat these conditions.
b. Varicose Veins. A varicose vein is a condition that is probably because of excessively prolonged pooling of blood in the lower extremities (for example: legs). Varicose veins are especially common in people who are required to stand for prolonged periods of time with little or no exercise.
c. Peripheral Vascular Disease. Peripheral vascular disease is characterized by vasoconstriction of the arteries (especially in the extremities). Decreased blood flow to the extremities and corresponding hypothermia are some of the usual signs of this condition.
