When we have a small cut or injury, then it results in breakage in the blood vessels and it starts bleeding. After some time, the bleeding stops and we can see that the blood has thickened and clots are formed at the injury site. The blood clotting process is influenced by the inner lining of the blood vessels, blood proteins, and blood platelets. Thus the body seals up an external injury by clotting up the blood, preventing loss of blood. However, if the clotting takes place inside the blood vessels then it could be a serious health complication. A blood clot inside the blood vessels is referred to as a thrombus. In the following sections, we are going to discuss about what causes blood clot in various parts of the body.
Causes of Blood Clots
There are various reasons that can lead to blood clots in the human body. Depending on the location of the clot, these reasons can differ. The following paragraphs give information on what causes blood clots in different parts of the body.
What Causes Blood Clots in the Brain?
The carotid arteries are those blood vessels that are located in the neck area and are responsible for supplying oxygen-rich blood to the brain. If any clot is formed inside these particular arteries, then it will block the blood circulation in the brain and thus there will be deficiency of oxygen in the brain. This is a serious health condition and can cause mini stroke or transient ischemic attack. If a big blood clot is formed inside the brain, then it can lead to a stroke. These arterial clots occur due to deposits of plaque inside the arteries. High blood pressure, high cholesterol level, smoking, diabetes, etc. mainly trigger these kind of arterial clots.

What Causes Blood Clots in the Lungs?
The pulmonary artery is the one that extends from the heart to the lungs. If a blood clot or thrombus from any part of the body travels through the bloodstream and gets stuck inside the pulmonary artery, then the condition is known as pulmonary embolism. This kind of blood clots blocks the blood from reaching out to the lungs. This could be a life threatening condition. Any kind of damage in the lungs, deep vein thrombosis, abnormal heart rhythm (or atrial fibrillation) are some of the factors that are often held responsible for this kind of clotting of blood inside the lungs.

What Causes Blood Clots in the Legs?
Clotting of blood inside the veins of the legs is termed as deep vein thrombosis. Immobility of the legs for a prolonged period of time mostly gives rise to this kind of health condition. Surgery, hospitalization, the use of a cast or splint forces the legs to stay in an immobilized state for a long time. Long air travel or road travel can also minimize the mobility of the legs. As the blood get pulled towards the legs due to gravity, lack of movements tend to lead to formation of blood clots in the legs. Pregnancy, smoking, hereditary clotting disorders, etc. can give rise to deep vein thrombosis. Blockage in the femoral artery of the legs can also cause blood clots in the legs. If left untreated it can lead to serious infections like gangrene.
What Causes Blood Clots in Eyes?
Blood clots in the eye are mostly formed due to injury to the eyes. Other than that, vigorous rubbing of the eyes, excessive eye strain, coughing, sneezing, high blood pressure, etc. can also give rise to this condition. The clots of blood formed in the eyes can change position from time to time. If it exists for a long time, then it can lead to loss of vision. Smoking can thicken the minor clots and make them hard to dissolve. The eyes should be rested as much as possible when there are any blood clots in the eye. In newly formed clots, warm compression or application of rose water can be helpful. If it does not work, medical intervention should be sought.
What Causes Blood Clots During Menstruation?
Many women have multiple blood clots in the flow during menstruation and it is normal. These mainly occur on the heaviest days of bleeding. The natural mechanism of the body is to release anticoagulants to prevent the menstrual blood from clotting. However, when the period is heavy, the blood is expelled so rapidly that the anticoagulants are unable to work normally. This leads to formation of blood clots. Also go through menstruation blood clots for more information.
Blood Clots Treatment
The treatment for blood clots is based upon the location, size and overall health condition of the patient. If blood clot in the artery leads to heart attack or stroke, then it has to be treated aggressively. It involves administration of medicines directly to the clots to dissolve them fast. In serious cases, arterial clots are removed by the means of surgery. In case the clot is formed in the veins, particularly in the lower part of the body, then there are higher chances of pulmonary embolism. Hence, the size and location of the clot has to be monitored with the help of ultrasound examinations. Initially, blood thinners like heparin is injected into the fleshy tissue to reduce the clots. Then warfarin is prescribed which has to be taken orally. Sometimes, application of heat, pain killers, etc. are found to be helpful for the reduction of swelling of the affected area.
Hope you have got a clear idea about what causes blood clots and how it should be treated. Since the condition can give rise to life threatening conditions, prevention of blood clot formation is essential. It can be achieved by following a healthy diet, doing regular exercises, which include calf and leg exercises, and maintaining proper body weight.
