A blood clot which forms in the deep veins of the leg is otherwise known as a deep vein thrombosis (DVT). DVT causes painful swelling making your legs feel hot to the touch and red in appearance. The primary concern of deep vein thrombosis is that a section of the clot could break away and navigate through your circulatory system and into the lung cavity. If such a thing were to occur the particle could start to form a pulmonary embolism which runs a significant risk of blocking off the major blood vessels supplying the lungs which in turn can prove fatal.

Deep vein thrombosis can manifest itself in a sudden onset of pain in the calf or thigh muscle with one calf swollen to round an inch greater than the other car muscle. If you identify freshly swollen veins in a painful limb this can also be a sign of DVT and in either of these cases you should seek medical advice immediately.
Any activities which makes the blood more likely to clot within the veins will place an individual at risk of suffering from DVT. Some of the common risk factors include long haul air travel, people who are immobile, pregnant women, obesity sufferers, smokers, the elderly, and a people with a family history of deep vein thrombosis. Family histories take place when a genetic malformation is passed from one individual to another within the same family. If you have a mother, father or sibling who showed symptoms of DVT without any specific causes it is a good idea to discuss this with your doctor or medical practitioner and talk through the possibility of taking a blood test to ascertain whether or not you are also prone to suffering from DVT.
One of the most efficient methods of preventing deep vein thrombosis is by keeping active. When taking a long haul flight take time within the journey to get up and walk around and remember to curl your feet and exercise your calf muscles by pulling your feet in different directions thereby helping blood flow. Quitting smoking and losing any excess weight will also help prevent the risk. It is relatively well known that women who take the combined contraceptive pill run a greater risk of contracting DVT. There are many alternative contraceptive pills on the market which are not associated with this increased risk and therefore it may be an option to change your contraceptive method. Do however consult with your doctor or medical practitioner prior to stopping the contraceptive pill.
