"Many young people today hardly move themselves from the computer, either for work or entertainment," says Que. "Sitting in one position for hours usually results in blocked or stagnant blood and energy flow in the legs, causing hidden trouble."

Reinforcing healthy energy, unclogging energy channels and promoting blood circulation is the main strategy. Chinese patent drugs like "Bu Zhong Yi Qi Wan" (pill of reinforcing zhong jiao and replenishing qi) is often prescribed.

Herbs that reinforce energy like huang qi (milk veteh) and dang shen (radix codonopsitis) are recommended. A nutritious diet with more fruits and vegetables helps.

TCM recommends foods that stimulate blood circulation and resolve blocked energy and blood, such as hawthorn, rapeseed plant and red phaseolus bean. Beef, mutton and chicken also warm and unclog energy channels.

Acupuncture, moxibustion and massage on acupressure points promote synergy and blood circulation and relieve pain. Stimulating acupuncture points like zu san li (three inches below the sunken point at the outer knee) and san yin jiao (three inches above the ankle bone on the inner side of leg) are used in treatment.

As it is almost impossible to restore enlarge veins to normal and reverse the condition, (surgery and other treatments are possible), prevention control at early stages is important, according to Dr Que.

Avoiding sitting in one position, standing or bending for long periods. If you cross your legs, change legs often. Desk workers should take breaks, walk around a bit, stretch their legs. While seated, lifting the legs occasionally helps circulation.

Women should avoid tightly cinched belts and tight waists as they hinder blood circulation in the lower body. Wear loose, comfortable clothes at home. Overweight people should shed some pounds to ease pressure on their leg veins.

Regular physical exercise, such as jogging, swimming or cycling, can promote blood circulation in the legs. Swimming also helps improve elasticity of the veins, and taking a dip is especially healthy.

In early stages, special compression stockings are effective in relieving varicose veins, as it promotes blood circulation in the legs by applying external pressure.

Simple exercise, such as squatting and then standing up, can promote blood circulation in the legs. Massaging the legs at bedtime is a good idea. Elevate the feet about 15 degrees above the bed. This will relieve pressure on leg veins and promote blood circulation.
