profligate coagulation , also calledcoagulation , is a vital process the organic structure uses after an injury to stop bleeding and help foreclose infection . But sometimes , blood coagulum mold inside an artery or mineral vein , where they can cause damage or even lead to dying .
So what causes origin coagulum ? And what make water them more potential to mould ?
Dangerous blood clots can form when there are too many “coagulation factors” in the blood.
A blood line coagulum can work when a blood watercraft is wound . This kicks off a string of effect that cause aprotein called thrombin to accumulatenearby . The thrombin then activates morsel of cell called platelets in the blood , causing them to form a plug that cover the injury land site .
These platelets also bond factor I , another bloodborne protein . Thrombin converts this fibrinogen into a knotty protein call fibrin , which forms a mesh that bridges the blood platelet to reinforce the plug . Once the combat injury has healed , these clot dismiss .

Certain conditions, including genetic diseases, cancer and some viral infections, can increase the risk of blood clots.
In some fount , though , blood clot can form when there is n’t an acute injury . This happens when factors in the profligate make it more probable to clot ; blood vessel linings are damaged over time by disease ; or blood stream is restricted , for model , by plaque buildup caused bycoronary arteria disease .
Medically know as athrombus , a rakehell coagulum that forms in one of these ways may outride in the blood watercraft without dissolve and block the musical passage of line . This can make tissue damage if the clot cut off blood flow completely . If thrombi frame in the heart , they can lead to heart attack . If they shape in the mastermind , they cancause stroke .
If some or all of the coagulum breaks idle from its original site , it is called anembolus . Broadly , embolus are masses that move through the bloodstream and can get stuck if they gain a vessel that ’s too narrow .
Such roving coagulum are specially grave because they can travel to any part of the body . In a experimental condition calleddeep vein thrombosis(DVT ) , a clot form in a large vein , often in the legs , and can break away off and travel to the lungs . That is then visit apulmonary embolism , which is a life - threatening medical emergency .
" I can not stress how authoritative it is to make out the symptoms of a line clot,“Dr . Rachel Rosovsky , director of thrombosis research in the Division of Hematology at Massachusetts General Hospital , told Live Science . " If you have a DVT , it could be leg pain , red or swelling . For a pulmonary intercalation , it could be dresser painful sensation , pressure , abruptness of breath or a dissipated heart pace . "
It ’s important not to ignore these symptom , especially if you are at risk of a stemma coagulum , because a successful retrieval oftendepends on quick treatment .
Some disease make blood more probable to clot . There aregenetic conditionsthat increase the levels of clotting proteins in the lineage ; reduce the layer of proteins that preclude or break up clots ; or otherwise impair those proteins ' functions .
Other weather condition — admit cancer , autoimmune diseases , high blood pressureandinfections like COVID-19 — may also project off the dead body ’s soft correspondence of coagulation factors . In COVID-19 , a combination ofexcessive inflammationandrogue antibodiesare thought to increase the blood ’s propensity to curdle .

Bothpregnancyand hormonal discourse , such assome shape of birthing controland hormone replacement therapy , are tied to an increase endangerment of blood clots . Research suggests thatanxiety and depression may boost the risk of infection of DVTby increasing tension - associate nervous activity tied to coagulum organisation .
life style factors also contribute to a person ’s risk of blood clot . Smoking raises the risk byincreasing lighting in the bodyand make platelets more reactive . Obesity is also tied to a gamey hazard of blood clots ; this may be partly because indicate molecules made by productive cells canboost levels of clotting factorsand make platelets stickier .
By limiting a person ’s mobility , long - haul travel , injuries such as bone cracking , and major surgeries can all temporarily increase the endangerment of dangerous clots . That ’s because less front intend less rakehell flow , more inflammation andmore energizing of clotting factorsin response to that inflammation .
Some of these risk constituent can be mitigated , though .

" If you sit down at a desk all solar day , get up and take the air around every hour , " Rosovsky order , supply that sit down traveler should wear compression stockings ortake regular movement breaksduring their journey . She also recommended that , in general , people stay well hydrous , maintain a healthy weight , engage in physical activity and forfend smoking .
" justly now , someone expire of a blood clot every six minutes , " Rosovsky said . As many as100,000 die of line clotseach year in the U.S. Rosovsky stressed that it ’s important to have a go at it your risk factors and how to palliate them , but also , to be cognizant of the signs and symptom of blood clots and assay medical attention if you experience them .
