After they occur on the surface, blood clotting could be a good factor to assist forestall extreme bleeding after you’ve been injured. Platelets (a kind of blood cell) and proteins in your plasma (the liquid a part of the blood) band collectively and type a clot over the damage, which finally dissolves as soon as the damage has healed.
Blood clots that strike contained in the physique, nonetheless, can typically block a vein or an artery and have critical penalties. A clot that blocks a vein deep within the physique is what’s often known as deep vein thrombosis (DVT). DVTs can type in any deep vein nevertheless it usually develops within the decrease leg, thigh, pelvis or arm.
It’s estimated that as many as 900,000 individuals throughout America can develop a DVT every year, in response to the Facilities for Illness Management and Prevention. And it’s not solely a illness of the aged or extraordinarily sick.
“DVTs can occur in younger patients without obvious medical issues,” Dr. Vincent Varghese, a board-certified interventional heart specialist at Deborah Coronary heart and Lung Middle in New Jersey, instructed HuffPost. “Awareness and education are critical in early recognition of DVT.”
Why and the way DVT blood clots usually manifest
The blood in our physique exists in a extremely regulated stability between selling blood clots (thrombogenesis) and breaking them down (thrombolysis), Dr. Ok. Francis Lee, medical director of Superior Vein Care Middle in Springfield, Massachusetts, instructed HuffPost.
“This fine balance is tilted to one side or the other as the need arises,” Lee defined.
However there are danger elements that may disrupt this homeostasis, which is categorized as both acquired or inherited. “Acquired risk factors include common ‘trigger’ events, such as trauma (major bone fractures), major surgery, immobilization (long-term sedentary or fixed body position, such as following surgery or during long trips), serious infections or cancer,” Lee stated.
The venous system is taken into account a passive circulate system with low stress — the muscle groups within the legs and arms actively pump blood by way of the vein system, again to the center and lungs. “When a person is unable to move (say, after a major abdominal surgery), then those muscles in the legs and arms aren’t actively moving to pump blood effectively,” Varghese stated. “This can lead to a slowing down of blood flow and possible blood clots.”
Blood thickens round matter that doesn’t belong within the veins — so issues like tissue particles, collagen or fats that could be launched into the blood system after a trauma or main surgical procedure may cause blood to clot too. And if there’s harm to the vein partitions, this may launch naturally-occurring substances that promote blood clotting, in response to the American Academy of Orthopaedic Surgeons (AAOS).
“There’s also an overall inflammatory response in these conditions, which can activate the clotting cascade and lead to blood clot development,” Dr. David Nation, a board-certified vascular surgeon at VeinSolutions in Austin, Texas, instructed HuffPost.
In the meantime, sure drugs (contraception drugs, hormone alternative remedy) and illnesses (coronary heart failure, kidney illness, most cancers) can result in a thickening of the blood as a consequence of numerous mechanisms, with the potential danger of DVT. There are additionally dozens of genetic situations that may improve an individual’s danger of not solely growing DVTs however early-age coronary heart assaults and strokes.
“As a layperson, it’s not practical to remember nor be concerned with every inherited genetic factor for developing blood clots,” Lee stated. “But any devastating occurrences (heart attack, stroke, blood clots, recurrent miscarriages) to a family member in their 20s to 40s in age should raise suspicion for an underlying inherited genetic condition that should be tested.”
“DVTs can occur in younger patients without obvious medical issues. Awareness and education are critical in early recognition of DVT.”

COVID-19 may improve your danger of DVT blood clots
The mechanisms behind why COVID-19 might improve the chance of DVT aren’t absolutely understood but, however there are a couple of theories.
“The virus creates an inflammatory state, which can lead to blood clotting too easily,” Nation stated. “It also causes direct endothelial injury to the lung tissue — damage to the cells that line the interior surface of blood vessels — that can release signals into the bloodstream that stimulate clot formation.”
It’s additionally been recommended the virus might immediately activate the clotting cascade by way of interactions inside the bloodstream. All of those results are extra distinguished in sufferers with a extreme COVID-19 an infection and far much less frequent in delicate instances.
Then there’s the immobilization issue — from spending days in mattress to weeks in intensive care — that may result in slower blood circulate, and in consequence, elevated danger of blood clot formation.
“People with COVID-19 or recovering from it should know the key strategy to avoiding DVT is heightened awareness of symptoms and prevention, with prevention largely provided by anticoagulation medications, better known as blood thinners,” Lee stated.
Preventative anticoagulation is acceptable for many, if not all, hospitalized COVID-infected individuals except there’s a contraindication. “Specific indications, type, and dose of anticoagulation should be determined by your medical providers,” Lee stated.
Individuals who’ve recovered and are being discharged from the hospital don’t want routine preventative measures for anticoagulation.
“People with risk factors that place them at high risk for DVT should be covered with preventative anticoagulation upon discharge from the hospital,” Lee stated. “Although not routine, preventative anticoagulation upon discharge for a period of time appears to be beneficial for those high-risk people.”
Lee added: “Certainly, those patients who developed DVT while in the hospital should stay on anticoagulation upon discharge for a period of months, as determined by their physician.”
What about if you happen to have been contaminated with COVID-19 however not sick sufficient to be hospitalized? You most likely don’t require routine preventative blood thinners, however when you’ve got any of the chance elements for DVT — latest surgical procedure, trauma, extended immobilization as a consequence of extreme sickness, household historical past — you need to be preventatively anticoagulated.
The greatest methods to guard your self from DVT blood clots
Whether or not you’re in your common state of well being or recovering from bodily trauma, surgical procedure or an infection, one of the best ways to keep away from DVT is to take away or decrease as many acquired and inherited danger elements as doable.
Signs of DVT embody swelling, ache or tenderness in your leg, ankle, foot or arm. Different much less frequent signs and indicators embody hip, thigh or again discomfort, unexplained palpitations, fever, dizziness, coughing with tinged blood or common fatigue and malaise.
“These symptoms may seem unrelated to blood clots in the legs, but they may portend early warnings of a serious DVT blood clot in the making,” Lee stated. The faster you act, the higher your outcomes.
Exercising commonly improves blood circulation and is likely one of the most vital issues an individual can do to stave off DVT. “Take a break at work if you sit all day by walking around your work area,” Dr. Sanjay Bhojraj, a board-certified heart specialist with Windfall Mission Hospital in Orange County, California, instructed HuffPost. “Schedule longer walks, take standing breaks and make sure to periodically stretch.”
Even one thing so simple as pumping your toes when sitting for prolonged intervals — by lifting your toes within the air for 3 seconds together with your toes flat on the ground — can provide your circulation a lift throughout occasions once you’re extra sedentary. The extra you progress round, the much less probability you will have of growing a DVT blood clot.
Be aware of medicines.
Sure drugs, resembling contraception drugs and chemotherapy, can improve your danger of blood clots.
“When a treatment is unavoidable, be sure to consult with your doctor about prophylactic anticoagulation options,” Lee stated, and take your drugs precisely as prescribed to maximise efficacy.
Compression socks might assist circulation by stopping blood from pooling within the veins, not solely bettering blood circulate however stimulating the physique’s personal capability to forestall blood clots, in response to the American Academy of Orthopaedic Surgeons.
This can be a significantly useful technique to make use of when touring, after surgical procedure or throughout different bouts of inactivity, like when at your desk working.
“If you’re planning to travel on an airplane, wear loose-fitting comfortable clothes, drink plenty of water and stay active by walking around every hour or so,” Bhojraj stated. “You should also change your sitting position often and avoid crossing your legs throughout your flight.”
“Smoking restricts blood flow and increases the risk of blood clots,” Bhojraj stated. “It’s never too late to quit.”
Comply with a post-surgery protocol.
If it’s a must to bear main surgical procedure and might’t be bodily energetic, your physician will most likely implement low-dose blood thinners in both capsule or injectable types, or compression gadgets in your legs, to stop blood clots, Varghese stated. They may additionally promote early ambulation (strolling or different actions) to decrease your danger.
The size of time you’re on the protocol will range, relying on the kind of surgical procedure you’ve had and your different danger elements, however following the protocol — and staying in shut contact together with your physician about the way it’s going — is a super-important a part of having a DVT-free restoration.
Hunt down your loved ones historical past.
Look into whether or not or not you will have a household historical past of blood clot occasions, resembling early-age coronary heart assaults, strokes, DVTs or unexplained being pregnant problems.
“If such family history is present, then consult with your physician or a hematologist on whether genetic or hematologic testing may be indicated,” Lee stated. “If one family member tests positive for any abnormality, then test everyone among the appropriate family circle in consultation with the physician.”
This information may be lifesaving — not only for you, however probably on your dad and mom, siblings and kids too.
What to do if you happen to suspect a DVT blood clot
Should you expertise sudden and protracted swelling, ache or tenderness in your leg, ankle, foot or arm that seems like a charley horse (a sudden and painful muscle cramp) and these signs stick round for greater than a day or two and worsen, make an appointment together with your physician straight away — and when you’ve got shortness of breath or expertise sharp chest pains, name 911.
If you see your physician or go to an emergency room, you’ll obtain a bodily examination. A physician will ask you questions on your well being to assist decide the chance of a DVT blood clot.
Be certain to allow them to know if you happen to’ve had a latest surgical procedure or critical damage (assume: breaking a bone), most cancers, stroke, coronary heart failure, are taking hormones (resembling contraception drugs) or have traveled for an prolonged interval, as these can all improve your danger.
A DVT blood clot is normally recognized by ultrasound of the extremity. Relying on the scenario, superior imaging — together with a CT, MRI or venogram — could also be wanted.
Blood thinners are the go-to remedy, which helps to dissolve the clot, and are both given intravenously or in capsule type.
“In the past, the only blood thinning pill was Warfarin, which required frequent bloodwork to monitor levels and efficacy,” Varghese stated. “We now have several blood thinning medication options that appear to be safer, better tolerated and don’t require frequent blood work.”
In additional extreme instances, your doctor might suggest eradicating blood clots out of your legs or lungs utilizing minimally invasive procedures or surgical procedure.
“Veins that are cleared of blood clots lead to much healthier outcomes than those that have residual blood clots or scarring remaining inside the vein,” Lee stated. “Early diagnosis and aggressive treatment can lead to satisfactory long-term clinical outcomes.”
