Q. What are varices? Why are they more common in the inferior limbs?

Varix means abnormal enlargement of veins and the Varices occur when excessive pressure against the normal blood flux creates enlargement of the vein and thus inadequate functioning of its valves (venous insufficiency).

Varices are more common in the veins of the inferior limbs since the fluid column above these vessels is higher this is the reason why people that spend much time standing for example, surgeons are more susceptible to varices.

In general varices aren't the apparent superficial veins that appear in the leg of varix patients these apparent vessels are the consequences of internal varices that is (venous insufficiency) in the deep internal veins of the legs and they appear because the blood flux is diverted to superficial veins (Popularly however apparent superficial veins are called varices.).
