Understanding the Causes and Risk Factors of Deep Vein Thrombosis

Deep vein thrombosis (DVT) is a potentially serious condition that can occur when a blood clot forms in one or more of the deep veins in the body. While DVT can occur in anyone, there are certain causes and risk factors that can increase a person’s chances of developing this condition.

It’s important to understand these factors and take steps to lower your risk of DVT, as it can lead to serious complications such as pulmonary embolism. If you experience any symptoms of DVT or are at risk, it’s important to seek medical attention right away. In this article, we’ll discuss the causes and risk factors of DVT and offer tips for prevention, so you can take steps to protect yourself and your health.

DVT Causes

Understanding the causes of deep vein thrombosis is critical to reducing your risk of developing this potentially serious condition. Let’s explore some of the most common causes of DVT, so you can be better informed about your health and take steps to protect yourself.

Being Immobile

Blood clots are likely to form during times when a person is restricted in their ability to move around, such as during long periods of travel or while working. Hospital stays are also known for causing DVT.


Pregnant women have a higher risk of developing blood clots because the baby puts pressure on the woman’s blood vessels which can impair circulation.


Some people may have inherited blood clotting disorders that cause their blood to be thicker than normal, making them more prone to developing clots.


Any injury, whether accidental or intentional, can cause a blood clot to form inside one of the deep veins which can later develop into DVT.

Blood Vessel Damage

Our blood vessels and veins can become damaged. It’s most likely to occur if you badly hurt your muscle or fractured a bone, the inner lining of a nearby vein could have been damaged.

Risk Factors

It can occur in anyone, but certain risk factors may increase a person’s chances of developing DVT. Read about some of the most common risk factors for DVT, including both controllable and uncontrollable factors, below.

Inactivity or a Sedentary Lifestyle

Exercise is one of the best ways to protect against blood clots because inactivity and a sedentary lifestyle are among the biggest culprits for blood clots to occur.

Overweight and Obesity

Obesity can increase pressure in the veins in a person’s legs and pelvis which puts them at a higher risk for developing clots.


Smoking has a huge effect on blood clotting and circulation, greatly increasing a person’s chances of having DVT.

Health Issues

Certain health issues and conditions can create a risk for DVT that otherwise wasn’t there.

Family History

Another risk factor is a family history of DVT or pulmonary embolism.

Lower Your Risk Today

While deep vein thrombosis is a serious condition, understanding its causes and risk factors is a critical step in reducing your chances of developing this condition. By taking steps to protect your health, such as staying active, maintaining a healthy weight, and seeking medical attention if you experience any symptoms of DVT, you can lower your risk.

Remember, DVT can be life-threatening, but it is often preventable. If you are at risk for DVT or experience any symptoms, it’s important to seek medical attention right away. With the right knowledge and proactive approach to your health, you can reduce your risk of DVT and maintain a healthy, active lifestyle.
