Varicose Viens

Veins are thin-walled vessels through which the impure blood is carried back to the heart. They usually have valves which regular the flow of blood towards the heart. Varicose veins are a condition in which veins become enlarged, dilated or thickened.

Varicose veins can occur in any part of the body but generally appear on the legs. The veins of the legs are the largest in the body and they carry the blood from the lower extremities upwards towards the heart. The direction of circulation in these vessels is largely determined by gravity. Though there are no mechanical obstacles to blood-flow, it is usually the incompetence of the valve which leads to an increase in intravenous pressure.

Varicose veins have an unsightly appearance and can be dangerous. A blood clot within a large, greatly dilated vein may breakaway and move toward the heart and lungs, causing serious complications. Varicose veins are about thrice as common as occurrence in women as in men. This disease is rare in rural undeveloped societies.

Symptoms

The first sign of varicose veins is a swelling along the course of the veins. This may be followed by muscular cramps and a feeling of tiredness in the legs behind he knees. In some cases, the normal flow of blood towards the heart may be reversed when the patient is in an upright position. This results in venous blood collecting in the lower part of the legs and the skin becomes purplish and pigmented, leading to what is known as varicose eczema or varicose ulcers. Both conditions cause severe pain.

Causes

A varicose condition of the veins results from sluggish circulation due to various factors such as constipation, dietetic errors, lack of exercise and smoking. Standing for long periods and wearing tight clothing's can also lead to sluggish circulation. Pregnancy may cause varicose veins due to increased pressure in the pelvis and abdomen, which slows down the flow of blood from the lower extremities to the heart. Women usually suffer from this condition in the early years of child-bearing. Obesity can also cause varicose veins.

Treatment

For a proper treatment of varicose veins, the patients should, in the beginning, be put on a juice fast for four or five days or on all-fruit diet for 7 to 10 days. A warm water enema should be administered daily during this period to cleanse the bowels and measures should be taken to avoid constipation.
