A blood clot in the leg is a medical emergency. A blood clot forms in a deep vein in the leg, which can lead to a life-threatening pulmonary embolism. We will tell you the exact symptoms and causes.

What is a blood clot in the leg?

Leg vein thrombosis, also called deep vein thrombosis (DVT), is a medical emergency in which a blood clot forms in one of the deep veins in the leg. This can lead to serious and life-threatening complications if the clot travels to the lungs and causes a pulmonary embolism.

Symptoms of a blood clot in the leg

But how do you recognize vein thrombosis in the leg? Various symptoms can occur:

Swelling in the leg

Warmth, redness, or pain in the affected leg

Feeling of heaviness in the affected leg

Skin discoloration or bluish color in the leg

Fatigue and shortness of breath

Less common but serious: occurrence of fever.

Important: If you suspect a blood clot, you should consult a doctor immediately to avoid complications such as pulmonary embolism.

Causes of blood clots in the leg

A blood clot in the leg can be caused by various factors. The most common causes include sitting or standing for long periods, which affects blood flow in the leg veins. This is especially important during long flights, operations or bed rest.

Genetic factors can also play a role, with some people being more likely to develop blood clotting disorders. Smoking and being overweight also increase the risk of blood clots. Some diseases such as cancer or cardiovascular disease can also lead to blood clots. Finally, taking certain medications, especially hormonal contraceptives, can increase the risk of blood clots.

Diagnosis and treatment of blood clots in the leg

A blood clot in the leg should be taken seriously and treated immediately. Diagnosis is usually made through examination and ultrasound. Treatment aims to dissolve the blood clot and reduce the risk of future blood clots. Medications such as anticoagulants or thrombolytics may be used for this purpose. In some cases, surgery may be necessary to remove the clot from the blood vessel.

To avoid blood clots in the leg, you should avoid any risk factors. To improve blood circulation, you should exercise regularly. During long plane or car trips, it is recommended to take regular breaks and exercise to promote blood circulation. Compression stockings are also recommended.

Aim to be at a normal weight and eat a healthy, balanced diet. Avoid drinking alcohol and smoking.
