Swelling of the leg may involve a noticeable distension of the shin or calf, ankles, feet or toes. Foot swelling may be a common occurrence which most of us will experience at some point in life after a long day of standing or sitting but may also be an indication of a more serious pathology as in certain cardiovascular disorders.
Recurrent or persistent swelling of the feet should be investigated by a medical practitioner especially if you have a history of cardiovascular disease or have noticed a change in color, sensation or mobility of the leg, foot or toe.
Blood rich in oxygen and nutrients flows through the arteries to the target area. Blood carrying deoxygenated blood returns to the heart via the veins where it is quickly routed to the lungs to be replenished with oxygen.
Blood flowing to the leg has to return to the heart through a group of veins with intermittent valves located throughout the course of the vein. This venous blood (blood in the veins that is returning to the heart) has to flow against gravity and since the pressure is usually lower at the feet, other muscles of the leg assist with 'pumping' this blood back to the heart. This muscle pump is most active when we are walking and least when we are standing stationary or sitting. Blood travels short distances up the vein and backflow of blood is prevented by a series of valves in these veins.
Working alongside the blood vessels are the lymphatic vessels which return lymphatic fluid (lymph) back up the body to empty into the blood system.
Swelling of the leg usually occurs as a result of an inadequate flow of blood or lymphatic fluid back up to the torso of the body. However other localized causes may further contribute to swollen feet, ankles or toes.
