What Causes Varicose Veins 
 
 

About varicose veins

Varicose veins are very common and affect around 60% of the adult population.

They are swollen, distended veins (usually on the legs) that look lumpy and bluish through the skin. 

Often they cause aching, pain and discomfort. Varicose veins may go on to cause thrombophlebitis, blood clots and eczema of the leg.  If untreated varicose veins may go on to develop leg ulcers.

The veins are the means by which blood is returned from the legs to the heart. Muscles in the calf and thigh act as pumps to push blood from the foot to the heart. When muscles relax, blood is prevented from running back to the feet by valves in the veins that close like gates.

Normal veins become varicose when the valves no longer work properly, allowing blood to back up [reflux] in the veins. The varicose veins you see in your legs are due to blood damming up in the superficial veins and branches.

Once you have developed varicose veins they will not get better without treatment and may deteriorate over time.

The symptoms most commonly associated with varicose veins fall into three categories:

Physical: Pain, tiredness and heaviness in the leg.
Visual: The tortuous blue varicosities seen running down the leg.
Long-term: Venous eczema, brown pigmentation, ulceration and bleeding.

It is important to stress that not all patients will suffer all the symptoms listed above.

Similar symptoms may have other causes than varicose veins.

Thread veins and reticular veins (also called spider veins or telangectasia) are also extremely common problems which many patients think are varicose veins. Thread veins vary in type, size and colour, ranging from fine red ones to larger purple or deeper blue veins.  They often appear to form the shape of a small spider on the skin, hence the term spider veins.

No one really understands why people develop thread veins on the legs, but the main causes seem to be heredity, pregnancy, hormones and minor injuries.

Some experts believe that many thread veins are the result of undetected varicose veins and unless this underlying problem is treated then the thread veins will recur following treatment.
