OREANDA-NEWS. Every year, a small blood clot causes hundreds of thousands of people due to impaired blood flow.  Experts told how to determine the presence of a blood clot in the vessels, naming the first signs to which attention should be paid.

 The danger of blood clots is that inside the blood vessels, they can grow and block the blood flow completely, which leads to strokes and heart attacks.  The disease does not develop overnight and, as a rule, thrombosis also has external manifestations.

 Experts called the first signs of thrombosis, after the appearance of which you need to immediately consult a doctor.  We are mainly talking about the swelling of one of the extremities: the doctors are sure that if the arm or leg has changed in volume, then this is a clear sign of vein obstruction.

 When, after a long walk, limping on one leg occurs, or there is very great fatigue, disproportionate to physical exertion, a thrombus can also be the cause.

 Frequent cough, accompanied by pain in the chest, but the MTP of the lungs does not reveal pathology, may indicate thrombosis.  Dyspnea that occurs without active physical activity, according to experts, can also be a symptom of blood clots in the lung area.
