What are varicose veins?
☞ Normal veins in the body are extended, stretched and twisted. Varicose veins mostly occur in the legs, but they may occur in the hands, arms, chest, or colon-rectum area.
What are varicose veins in legs?
☞ Varicose veins have a characteristic appearance like that of a “sunburst” or a “spider web” on the legs. They are generally blue, twisted and enlarged veins near the surface of the skin. Lying down or putting up the feet relieves the pressure, but after standing, it seems to get worse. Varicose veins appear in approximately 2% of the population and twice as often as in women than men.
Varicose veins often run in families. There is a 50 percent risk of developing varicose veins if one has parents with varicose veins or patients with congenital weakness of the vein valves or venous wall.
The enlarging uterus in pregnancy causes the large femoral veins to become obstructed.
3. Taking birth control pills & hormone therapy
Most contraceptive pills utilize a special ratio of progesterone to estrogen. Taking any hormone therapy, including oral contraceptive pills should be avoided when you have varicose veins in your legs.
4. Obesity. lack of exercise & constipation
Obese people have an increased amou nt of blood circulating than thin people. This leads to the accumulation of fat on the venous wall leading to weak venous walls. The lack of muscular exertion in people who work standing or sittting too long can result in weak muscles in the lower limbs and inactive blood pumping, leading to vascose veins.
The elasticity of the venous walls is decreased as one gets older so that the muscles in the calf are contracted leading to a high risk of varicose veins.
6. Smoking & bad eating habit
Smoking causes increased blood viscosity and blood pressure leading to a high risk of damaged valves and venous walls. The flow of blood in the veins can be blocked when food containing high levels of colestrol and fat which can leads to varicose veins.
1. Hardening of blood vessels
Injecting medicine to harden the blood vessels irritates the lining of the vein causinvg hardening of the vessels and the area about the vein to close up.
2. Subcutaneous laser surgery treatment
Varicose veins can be removed by subcutaneous laser surgery. This treatment is effective for telangiectasia, Reticular varicose veins, and pigmented skin after sclerotherapy.
3. Endovenous laser treatment (EVLT)
By placing an intravenous catheter and burning in the blood vessel lining, blood backflow which is a cause of varicose veins can be prevented. This does not require hospitalization and general anesthesia . Also, one can return to a normal activity immediately after a surgery.
