Blood clots are a dangerous, life-threatening condition. A blood clot blocking the flow of blood can lead to death if it is not removed quickly. The veins in the lower extremities are most susceptible to thrombosis. Under certain circumstances it can help: https://pillintrip.com/medicine/klexane.

What are blood clots and why do they appear?
Blood clots are clots that form from blood cell compounds. Platelets stick together in chains and form clots that stick to the walls of blood vessels. In some situations, blood clots form due to disorders of the hematopoietic system, while in others they are the result of damage to the inner wall of the vessel.
Large growths inside the vein do not allow blood flow to pass the obstructed area. As a result, stagnation forms in the veins, leading to varicose veins. When a clot blocks the lumen, a heart attack occurs – the death of tissue that has not received oxygen with the blood flow.
Several factors in a person’s daily life influence the formation of blood clots:
Sedentary lifestyle. Lack
of active mobility leads to blood stasis in the lower legs. Therefore, constant sitting at the computer, as well as the choice of an escalator instead of stairs, give the blood a reason to stagnate and form clots.
Inadequate fluid intake. Blood quality is directly related to what a person eats. With insufficient fluid intake, the blood becomes thick, which means it cannot fully perform its functions and puts a great strain on the heart. Fluid blood is easy to pump through the system, but thick blood is much more difficult.
Taking medications that affect the hematopoietic system. Medical practice often uses drugs for the treatment of certain diseases, one of the side effects of which is blood clotting. Therefore, such medications should always be taken simultaneously with anticoagulants, which prevent blood clots.
You can protect yourself from clogged veins by regularly exposing your body to physical activity, drinking enough fluids, and including more plant foods rich in fiber in your diet.
Where do blood clots appear
It cannot be said that blood clots form predominantly in the veins, bypassing the arteries. Thick formations can appear in the vessels as well as in other ducts. In the arteries, thrombi form mainly due to the integrity of the inner surface of the circulatory system. Venous thrombi accumulate most often due to thickening of the consistency of the biological fluid, and vessels risk becoming blocked by thrombi when the intensity of blood flow decreases or clotting increases.
How blood clots arise
If a blood clot has formed on the artery wall, its appearance can be described in the following steps:
Some process damages the artery wall.
The body notices the disturbance and begins to build a defense against blood loss by forming a large number of special blood cells – platelets – which, when attached to the damaged area, form a kind of patching.
When clotting disorders or changes in the hematopoietic system, platelet formation does not stop in time and continues longer than it should. This results in an overgrowth on the wall. Or platelets, which are in small quantities in the blood, passing by with the blood flow, stick to the formed clump.
Causes that damage the vessel walls may be:
mechanical disturbance of the structure due to trauma;
high levels of glucose molecules in the blood;
Immune system dysfunction.
If there are no factors contributing to thrombus formation, any trauma or other injury will not lead to a large accumulation of blood cells. Under the layer of thrombocytes, the artery wall will tighten and repair itself, and the crust will eventually dissolve.
Several stages of thrombus formation are distinguished:
Disruption of the structure of the inner surface of the artery;
Activation of clotting factors;
the adhesion of platelets at the site of the injury;
appearance of substances triggering a chain of reactions, forming fibrin threads, which contribute to thrombus formation;
A network of fibrin filaments is formed in which blood cells are trapped, creating a large clot;
Over time, the clot thickens to form a clot.
When the clot breaks off under the influence of something, it begins to move through the bloodstream. Once it reaches the nearest bottleneck, blood flow is cut off. If such a situation occurs outside a medical facility, the person cannot be saved.
Factors of thrombosis
Increased risk of blood clots is caused by:
Genetic heredity to predisposition.
Diseases that force to limit physical activity, such as bed rest.
A high degree of blood clotting.
Arrhythmia, cardiomyopathy and other diseases that disrupt the strength and rhythm of blood flow through the system.
High body mass index.
Age-related changes in hormone levels in both men and women.
Some of the factors listed cannot be influenced, such as genetic predisposition. However, you can protect yourself from serious consequences of blood clots by leading an active and healthy lifestyle.
When to suspect a blood clot
Seeking medical help at the first signs of thrombophlebia can be life saving. Therefore, it is important to pay attention to the following symptoms:
Temporary lameness unrelated to an obvious injury, or sudden difficulty moving the leg. As a rule, the other leg, in this case, is amenable to the commands of the brain without impairment.
Appearance of visible vasculature on the skin, which has resulted from the accumulation of large volumes of blood due to obstructed blood flow.
Sudden difficulty in breathing.
Unexplained weakness without physical or mental exertion.
Tinnitus in the ears.
Temporary and sudden confusion of consciousness.
Most often these symptoms are caused by a small-diameter clot that has broken off and creates a temporary obstruction to blood flow. Under pressure, it breaks into smaller fragments, so that blood flow is restored and the patient’s condition normalizes.
