Blood clots – causes, signs, prevention

Blood is not just a liquid that moves through blood vessels. It is a very complex organ of the human body. It is prone to many diseases and the appearance of various formations. A blood clot is a blood clot in the lumen of a vessel or heart cavity. Once attached to the wall of a vessel, it not only prevents blood flow, leading to ischemia (decreased blood supply) in the area where it appears. When the clot breaks off and moves with the blood flow, it can cause a sudden blockage of the vessel, which is a considerable distance from the place of formation. Doctors sometimes use this drug:

The following types of blood clots are distinguished:

-Arterial thrombi. They are formed from fat and cholesterol tissues, with time atherosclerotic plaque is formed around them: a neoplasm on the artery wall grows and thickens against cholesterol.

-Venous vessels are prone to phlebothrombosis. This is the formation of a clot at the site of an injury or damage inside the vessel.

The main causes of blood clots include the following:

-slow blood circulation in the circulatory system;

-Excessive clotting of the blood;

-Blood stagnation due to prolonged immobility;

-complications after surgical operations;

-High cholesterol levels;

-Overweight, diabetes, sedentary lifestyle;


Thrombi vary in size and location. The main types are:

-Thrombus that has formed on the wall of a vessel and has not blocked the blood flow, is called a parietal clot.

-A clot that has completely blocked the vessel and blood flow has stopped is called an occluding clot.

-A clot that is a blood clot and easily detaches from the vessel wall is called a flotating clot. This type of clot is most commonly found in the lungs.

-A clot that moves through the bloodstream is called a stray clot. Such a formation is also called an embolus.

You can recognize a thrombus if it interferes with the blood supply and symptoms of thrombosis appear:

Deep vein thrombosis of the lower leg: tumescence, pain, it becomes stronger when palpated in the area of the affected vessel, swelling, redness or blueness of the skin, increase in its temperature, pronounced venous network, crowded veins.
Pulmonary artery thrombosis: sudden onset of dyspnea, bluish skin with a gray tint, drop in blood pressure, chest pain, heart rhythm disorder, swollen neck veins, fainting, cough, wheezing, pinkish sputum, increased body temperature, pain in the right hypochondrium.
Coronary artery thrombosis: pain behind the sternum, radiating to the back, neck, occurs during stress physical activity, accompanied by shortness of breath, palpitations.
Arterial leg network thrombosis: chills, numbness in the feet, burning, pain when walking, stopping when you stop, skin becomes pale, and then fingers turn blue.
Cerebral artery thrombosis: dizziness, wobbling, various visual disturbances, slurred speech, decreased muscle strength and sensitivity in the arm and leg, memory loss.

Signs of a blood vessel rupture:

-If it occurs in the blood vessels of the brain, a stroke will occur.Signs of a stroke: speech impairment, paralysis of the face (usually left or right side), dizziness, paralysis of various parts of the body.

-If the clot clogs the jugular vein in the neck, you will experience dizziness, severe headache, and visual impairment.

-When a mass clogs a coronary artery, a heart attack occurs. This is manifested by a sharp pain in the heart area. The pain may be compressive, pressing. Sometimes it goes to the neck or arm, sometimes to the stomach or lower jaw.

-Necrosis, peritonitis, severe intestinal pain are signs of mesenteric thrombosis.

-If a thrombus clogs the vessels of the upper or lower extremities, the consequence is pain, discoloration of the limb, its temperature. Since a person is unable to tolerate pain in a bleeding limb for a long time, gangrene rarely occurs. Otherwise amputation of the limb is necessary.

-Blueing of the skin, shortness of breath, palpitations are signs of oxygen deprivation caused by pulmonary embolism. It is a consequence of pulmonary artery blockage by a thrombus. If the person is not treated promptly, he or she will die.

If a blood clot breaks off, you should act immediately. You should lay the person down, then call an ambulance. When calling, list all the symptoms, this will help the operator to send a specialist of the right profile to the place.

Thrombosis prevention includes:

-active lifestyle;

-Give up bad habits;

-Eating a healthy diet;
-Weight control;

-Contacting specialists at the right time.

A blood clot is a very dangerous phenomenon, because, growing inside the vessel, it gradually blocks the flow of blood, and therefore oxygen and other substances to human internal organs, including the brain, which can lead to death.
