If the cause of poor circulation of blood in the body is spider veins or varicose veins (both terms are used to describe damaged or weakened veins that lack the strength to sufficiently pump blood through to the rest of the body), there are procedures available that can be performed to drastically improve overall circulation. One of the most common procedures performed to treat veins resulting in increased circulation is sclerotherapy, which helps to reroute the flow of blood into the healthier, undamaged veins and away from the damaged veins, resulting in increased blood circulation. It works through the implementation of a solution into the veins that will cause the damaged veins to become irritated and eventually collapse, rendering them unusable by the body, naturally diverting the blood flow to other veins that can effectively circulate the blood.
