What Is Excessive Blood Clotting (Hypercoagulation)?
当你割伤或受伤时, 你的身体会形成血块, 增厚的血块, 帮助止血. Proteins in your blood (fibrins) work with small blood cell fragments (platelets) to form the clot. 这叫做凝固, 或凝血, a process that helps the body form a clot when an injury occurs because it slows blood loss.
After bleeding has stopped 和 healing has occurred, the body should break down 和 remove the clots. But sometimes blood clots form too easily or don't dissolve properly 和 travel through the body limiting or blocking blood flow.
This is called excessive blood clotting or hypercoagulation 和 can be very dangerous. In a case of excessive blood clotting, 这些血块会形成, 或者去, 动脉:任何器官的动脉或静脉, 这会导致 心脏病, 中风, damage to the body’s organs or even death.
Many factors can cause excessive blood clotting including certain diseases 和 conditions, 基因突变和药物. 的se causes fall into two categories: 收购了 和 遗传.
- 收购了 means that excessive blood clotting was triggered by another disease or condition. 吸烟, 超重和肥胖, 怀孕, use of birth control pills or hormone replacement therapy, 癌症, 长沙巴足球体育平台卧床休息, or car 和 plane trips are a few examples.
- 的 遗传, 或者继承, source of excessive blood clotting is less common 和 is usually due to 遗传 defects. 的se defects usually occur in the proteins needed for blood clotting 和 can also occur with the substances that delay or dissolve blood clots.
收购了 和 遗传 sources of excessive blood clotting are not related but a person can have both.
Some other names for excessive blood clotting are:- 高凝紊乱或状态
- Hypercoagulation
- 血栓栓塞的州
- Thrombophilia (a name used mainly for 遗传 conditions)
- 血栓性疾病
Why excessive blood clotting matters
的 outlook 和 treatment for excessive blood clotting depend on the cause of the blood clots, how severe they are 和 how well they can be controlled.
Some possible effects of blood clots include:- 中风 – A 中风 can occur if a blood clot causes blood flow to your brain to be restricted. If blood flow is cut off for more than a few minutes, the cells in your brain start to die. This impairs the parts of the body that the brain cells control. A 中风 can cause lasting brain damage, 长期残疾, paralysis (an inability to move) or death.
- 心脏病 – A blood clot in a coronary artery can lead to a 心脏病. A 心脏病 occurs if blood flow to a section of heart muscle becomes blocked. 如果血流不能迅速恢复, the section of heart muscle becomes damaged from lack of oxygen 和 begins to die. This heart damage may not be obvious, or it may cause severe or long-lasting problems such as 心脏衰竭 or 心律失常.
- 肺栓塞 – If a blood clot travels from a deep vein in the body to the lungs, it’s called a pulmonary embolism (PE). PE is a serious condition that can damage your lungs 和 other organs 和 cause low oxygen levels in your blood.
- 深静脉血栓 – A blood clot in a vein deep in your leg or arm can cause pain, 肿胀, redness or increased warmth in the affected limb 和 can cause deep vein thrombosis (DVT). 的se clots can break off, travel to the lungs 和 cause PE.
- 静脉血栓栓塞(VTE) - PE和DVT一起构成一个 静脉血栓栓塞.
- 外周动脉疾病(垫) – 垫 is a narrowing of the peripheral arteries, most commonly in the arteries of the pelvis 和 legs.
- 妊娠相关的问题 – Blood clots can cause miscarriages, stillbirths 和 other 怀孕-related problems, 比如先兆子痫, which is high blood pressure that occurs during 怀孕.
-
肾功能衰竭 – A blood clot in the kidneys can lead to kidney failure, where kidneys can no longer remove fluids 和 waste from your body.
通过药物和持续护理, many people who have excessive blood clotting can successfully manage it.
