When blood flows through the veins deep in the calves and thighs, it flows rather slowly. This is for two reasons.
When blood moves slowly, it has the tendency of clotting, even if you do not want it to. Once the clot forms, it gets larger and larger until it wedges itself in the vein.
Yes, Deep Vein Thrombosis is a serious condition, but it is not something common enough that you should center your life around it. The condition is actually extremely rare, and it only affects about 2 of every 1,000 people.
The blood clots associated with Deep Vein Thrombosis are not life threatening. However, they can cause complications that are fatal. The most common fatal complication is a pulmonary embolism. However, this only occurs in three out of every four cases of DVT.
DVT can also be lethal if a clot in the leg manages to break free and travel through the body. The clot then finds its way to the lung, blocking airflow and causing straining during inhalation. This condition requires medical treatment because it can lead to a pulmonary embolism. If untreated, the condition can lead to death.
DVT mostly affects people who work somewhere that involves sitting for 8 hours per day. This can be from working in a sitting position, or from flying for prolonged periods of time. It also affects people who live an extremely sedentary lifestyle. It also occurs frequently in workers who sit at their desk for eight hours per day without getting up and moving around to exercise.
If you sit for prolonged periods of time at a computer, make sure you can take periodic interruptions from sitting. Get up and do things that involve being away from your computer monitor, and up on your feet. Not only will this prevent the occurrence of DVT, it will also allow your eyes to recover from sitting at the computer screen, reducing the incidence of headaches. Use this time to move around and exercise away from your desk.
While you may be hesitant to take time out and move around away from your desk, there is a very good chance that your boss will not mind. Moving your feet in circles, fidgeting your toes, and stretching your legs can prevent blood from pooling.
