You must have noticed veins of your granny or grandfather bulging out and highlighting greenish veins. You may have thought that that it is a sign of weakness or old age. But when the same thing becomes visible in your aunt or someone in the middle age group, then it becomes a matter of serious concern.
Mr. Chhabra's wife has dilated veins in her left leg for the past many years and a lot of difficulty in walking. There is a black pigmentation and eczema- type rash on her calf and leg. An ultrasound report said that left sapheno-femoral junction is incompetent but left sapheno-popliteal junction is competent. Right leg is normal. Then they consulted a surgeon who said that Mrs Chhabra has got varicose veins."The dilated veins are called varicose veins. Varicose veins occur more frequently in females. Varicose veins are the penalty which we are paying because of the stressful and fast life of today where we lead sedentary lifestyles," says Dr. Sandeep Agarwal, consultant vascular surgeon.
Veins are the blood pipes, which take deoxygenated blood (impure blood) from legs towards the heart. Varicose veins are those abnormal small blood pipes, which are like a bunch and present just under the skin. These veins have valves which control the direction of blood flow, when these valves become incompetent then the blood doesn't flow towards the heart. Varicose veins develop mainly in the legs because the blood has to travel inside the veins against gravity. Why its occurrence is more in females? "It's due to two reasons. The female hormones can cause weakness in veins so the veins become dilated. The second reason is that during pregnancy, the foetus causes pressure over pelvic veins which in turn cause weakness and increase pressure in leg veins," adds Dr. Gupta.Exercising, losing weight, elevating your legs when resting and not crossing them when sitting can help keep varicose veins from getting worse. Wearing loose clothing and avoiding long periods of standing can also help. If varicose veins are painful or you don't like the way they look, your doctor may recommend procedures to remove them.
Fashion is playing havoc among ladies. High heeled sandals, tight belts and panties are significant contributors to the development of varicose veins, as these items obstruct the normal flow of blood in veins.
The heart pumps blood filled with oxygen and nutrients to the whole body. Arteries carry blood from the heart towards the body parts. Veins carry deoxygenated blood from the body back to the heart. The squeezing of leg muscles pumps blood back to the heart from the lower body. Veins have valves that act as one-way flaps. These valves prevent the blood from flowing backwards as it moves up the legs. If the one-way valves become weak, blood can leak back into the vein and collect there. This problem is called venous insufficiency.
Pooled blood enlarges the vein and it becomes varicose. Spider veins can also be caused by the backup of blood. Hormone changes, inherited factors and exposure to the sun can also cause spider veins.
"Not all varicose veins can be prevented. But some things can reduce your chances of getting new varicose veins," says Dr. Jagdish Sharma, vascular specialist. He suggests some ways:
Varicose veins usually occur when you put undue pressure on the legs.read more
Varicose veins occur when veins below the skin's surface are damaged, become swollen and fill with too much blood.read more
