There is no single factor identified to be the cause of DVT. DVT as condition is observed to be developed due to various factors or combination thereof. Some of the factors which are known to be the cause of DVT or which increase the probability of a person developing Deep vein Thrombosis are listed below:
- Heredity: It is observed that people with a family history of Deep Vein Thrombosis have significant high chances of developing DVT themselves.
- Weight: People who are overweight or obese tend to develop DVT as more pressure is exerted on veins in legs and pelvis.
- Any injury resulting in damage to veins may lead to onset of clot formation in the deep veins i.e. DVT as any major injury may affect the inner lining of any deep vein leading to clots.
- Medical conditions/ illnesses like heart disease, lung diseases, bowel inflammation disease, cancer also highly risk the chance of clot formations in veins.
- Pregnancy/ Hormonal therapy/ Consumption of birth control pills: All these may lead to increase in level of “Estrogen” in female body and which may assist in easy clot formation.
- Long Bed Rest or Seated for a long time: Non-movement of muscles for a longer duration sometimes lead to pooling of blood in lower legs and if combined with any other factors mentioned it greatly assists in development of Deep vein Thrombosis.
While development of DVT is more probable with increase in age, existence of any of the above factors may lead to onset of Deep vein Thrombosis at younger age.
