How To Maintain Quality Foot Circulation
All doctors of podiatric medicine have circulation as one of their main focuses. In the human body the arteries and veins of the feet are the furthest from the heart, and are most prone to decreased circulation.The arteries carry oxygenated blood away from the heart and the veins carry blood depleted with oxygen to the heart and lungs for an oxygen fill up. The oxygen in the blood goes out to the organs and tissues of the body, with the hands and feet as the last stop.
The two main arteries of the feet are the posterior tibial artery and the dorsal pedis artery. These arteries branch off thousands of times to all of the tissues during normal functioning. When fully functioning, these arteries are strong and supple, and they expand and contract in conjunction with the heartbeat.
50% of all mortality in the U.S. involves one form of cardiovascular disease or another. The most common cause of death in the U.S. currently is arteriosclerosis. When affected with arteriosclerosis, the veins become blocked, constricting blood flow to many sections of the body, including the feet. Since the feet are so far from the heart, they are often the most affected by arteriosclerosis blockage.
When there is a blockage in circulation, the muscles and tissues do not get their necessary oxygen supplies. Tingling and cramps may develop around the bottom limbs and feet. Your foot may tingle and become cold. Patients with decreased circulation may have cracking and weakening of their toenails.
Another circulatory deficiency affecting the foot are varicose veins. Veins are this thin walled arteries that return oxygen back to the lungs and heart, and they move up from the feet and limbs counter to gravity. When veins become varicose, the blood can get stuck traveling back to the heart, and the veins can swell and stop functioning.
