What Are the Warning Signs of a Blood Clot?

by | Nov 19, 2021 | Blog | 0 comments

Blood clots are healthy and lifesaving when they stop external bleeding but can be dangerous or even fatal when they occur inside the body. Internal blood clots form when blood doesn’t flow properly through the circulatory system. When this happens in the legs, it is known as a deep vein thrombosis (DVT). Not everyone with DVT will have symptoms, so it’s important to exercise regularly, quit smoking, maintain healthy blood pressure levels, and talk to your doctor at the first sign of trouble.

These jelly-like masses of blood in the veins are extremely dangerous because a DVT can break away from the vein wall and travel to other parts of the body. When it travels to the lungs it is called a pulmonary embolism, a potentially life-threatening medical condition. Most pulmonary embolism blood clots start in the legs and travel up through the right side of the heart and into the lungs. Blood clot warning signs include:

  • Sudden swelling in the affected leg
  • Pain, tenderness, or cramping in the leg when standing or walking
  • Skin discoloration (usually redness)
  • Feeling of warmth in the affected r leg
  • Enlarged veins near the surface of the skin

Causes of deep vein thrombosis

A blood clot, or thrombus, can form for several reasons, including one or more of the following circumstances:

  • Injury
    Trauma is one of the most common causes of DVT in the lower extremities.
  • Inactivity
    When you sit more and move less, the blood flow to your legs slows down. This can cause the blood to pool in the muscular beds of the calf, making it easier for a clot to form. This can happen on an airplane flight or a long car ride.
  • Hypercoagulation
    An imbalance of the proteins and cells responsible for blood clotting can cause a person’s blood to be thicker or stickier than usual.
  • Pregnancy
    During pregnancy, a woman’s blood naturally clots more easily to lower her risk of extreme blood loss during labor and delivery.
  • Surgery
    Blood clots can form when blood slows down or the inside of the vein is injured, each of which is common during and after surgery. Longer surgeries, particularly those using general anesthesia, pose a higher risk because of prolonged inactivity during the surgery and recovery.
  • Family history
    If an immediate family member has a blood clotting disorder, you have an increased risk of DVT.
  • Obesity
    Obesity increases your risk of stasis or stagnation of the blood in the veins, which also increases your risk of clot formation.
  • Age
    The risk of DVT increases after age 40.

Treatment options for DVT

The main goal for treating DVT is prevention. The first part of that goal is to prevent the clot from getting bigger. The second part is preventing the clot from breaking loose and traveling to the lungs. The third is to reduce your chances of developing another clot. Safe and effective treatment options include:

  • Compression stockings
    Medical-grade compression stockings lower your risk of blood clots and pooling in the lower extremities. They also help prevent swelling associated with DVT.
  • Anticoagulants
    Blood-thinning medications are commonly used to prevent blood clots from getting bigger and reduce your risk of developing more clots. Most anticoagulants are prescribed for at least 3 months.
  • Thrombolytics
    Clot-busting medications are prescribed for more serious cases of DVT or if other medications aren’t working. These medications can cause serious bleeding, so they are typically reserved for in-hospital administration for people with severe blood clots.
  • Filters
    Filters are an alternative surgical option for those who cannot take blood-thinning medications due to things like drug interactions. During the procedure, your vein care specialist will insert a filter into a large vein in your abdomen, called the vena cava. This is usually performed through one of the veins in the leg. This will help prevent clots that break loose from entering the lungs.
