What are Blood Clots

Blood clots are also called as thrombus or embolus which is a medical term. Blood clotting is important to repair the injured blood vessels. Blood clotting is also called coagulation. It prevents excessive bleeding. It will automatically dissolve when the injury gets healed. However, if the clots that are formed inside the blood vessels which are not meant to heal any injury does not dissolve automatically. These require immediate medical treatment otherwise it can cause danger to the person’s life. There are two types of blood clots:

Thrombus: These blood clots are formed in the heart or the blood vessels and stays in the same location. These clots do not move from one place to another.

Embolus: These blood clots are comparatively dangerous and move from one place to another.

An external clot is called scab and an internal clot is called bruise. There are many reasons which can cause blood clotting. One of them is to heal the injured blood vessels and other can be certain kind of illness and disease. A blood clot consists of both the platelets and fibrin strands. Both these help in preventing the blood flowing out. In arteries, the clotting system depends on platelets and in veins; the blood clotting mechanism depends on thrombin system. An abnormal blood clot which is caused due to some form of illness can restrict the blood to go to the heart and can cause pain and in turn it can cause a risk to the person’s life. Blood clotting in veins can be caused due to smoking, hormone therapy, pregnancy etc. Blood clotting in arteries can be caused due to high blood pressure, high cholesterol levels, smoking, and diabetes etc. Blood clotting can be seen in other areas of the body parts too like blood clots in urine, stool, rectal bleeding, bleeding during pregnancy. Clots can be formed in legs and arms too. Blue colored marks on your legs and arms indicate the formation of blood clots there. All these problems should never be ignored. These can be the sign of some major problem. Therefore, medical advice is essential. Blood clots can be diagnosed through CT scan, X-ray, ultrasound and MRI etc. doctors can provide you the medication only after knowing the root cause of the problem. In some cases, if the disease does not get cured with the medicines then a person might have to go through the surgery in which the clot will be removed.
