Varicose Veins, Thrombophlebitis, Blood Clots, and Pulmonary Emboli: Why They Happen, and to Whom

Dr. Larry Weinrauch Health Pro September 10, 2007
  • Varicose veins are large, often winding dilated veins that often stick out from under the skin and occur mostly in the legs. They occur because the valves in the veins that prevent blood from flowing backward (away from the heart rather than towards it) are not working properly. In some people this i...

    A pulmonary embolism is a blood clot that forms in an artery that carries oxygen to one or both of the lungs. In most cases, embolisms form in the lower extremeties, break free and then travel with blood flow toward heart and lungs. An embolism formed in the legs must pass through the heart before it reaches the lungs. Understanding how to identify symptoms...

    A pulmonary embolism is a blood clot that forms in an artery that carries oxygen to one or both of the lungs. In most cases, embolisms form in the lower extremeties, break free and then travel with blood flow toward heart and lungs. An embolism formed in the legs must pass through the heart before it reaches the lungs. Understanding how to identify symptoms of a pulmonary embolism can literally save a life. Most commonly found in adults, both females as well as males are affected by this type of blockage, especially after prolonged bedrest, injury, recent surgery, long periods of sitting and several other factors, including smoking and obesity.

    Blood clots can lead to many health complicatons including stroke and are more common among inactive and/or obese individuals.

    Blood clots are life threatening however exercise can help prevent their formation and assist in dissoving of existing clots. This fact was discovered and presented to the American Heart association in 2003 by the University of Colorado Health Sciences Center.

    The study found that levels of an essential blood clot dissolver known as tissue type plaminogen activator (t-PA) are greatly diminished in overweight men (by as much as 30%). This reduced protection in the blood stream leads eventually to problems with blood clots.

    Walking for a period of three months for a mere 45 minutes a day, five days a week however increased the amount of t-PA in the obese participants blood by as much as 50%. The study showed that after this walking regimine the obese subjects had similar levels of t-PA in their blood to that of lean participants in the study.
