Venous Insufficiency: What’s the Connection to Blood Clots & Health

Venous insufficiency is a condition in which your veins are unable to adequately return blood from your feet and legs back to your heart. This can cause a lot of problems, including increased risk of blood clots and other health issues. In this article, we’ll explore what exactly venous insufficiency is, how it relates to blood clots and how it affects your health.

What Is Venous Insufficiency?

Venous insufficiency occurs when the veins of your legs do not work properly. This can cause the blood to pool in the veins rather than flowing back to the heart. This can cause a number of uncomfortable symptoms, such as:

  • Swellings in the legs and ankles
  • Pain and discomfort
  • Aching in the legs
  • Fatigue or heaviness in the legs
  • Itching or burning sensation in the legs

The cause of venous insufficiency is usually due to weakened vein valves or weakened walls of the veins that don’t close properly. This can be caused by a variety of factors, including age, excessive standing, sitting, genetics, and pregnancy.

Venous Insufficiency & Blood Clots

Since venous insufficiency prevents your veins from properly returning blood to the heart, it increases the chances of developing a blood clot. Blood clots form when the blood collects and forms a mass in the vein. This can be a dangerous condition, and should be treated immediately if you suspect that you have a blood clot.

Since the blood flow is blocked, the oxygen needed to reach vital organs is also hampered. This can lead to other serious health complications that can be potentially fatal.

Other Health Risks of Venous Insufficiency

Other than an increased risk of developing a blood clot, venous insufficiency can lead to other health issues. These can include:

  • Skin damage – Poor blood circulation leads to the skin being deprived of oxygen, which can result in skin damage such as thickening, discoloration, and ulcers.
  • Leg ulcers – Venous insufficiency can cause ulcers to develop in the lower legs, which can be painful and difficult to treat.
  • Lung problems – Blood clots can also travel to the lungs and cause an array of respiratory problems.

Treating Venous Insufficiency & Blood Clots

Venous insufficiency and blood clots can be treated, but it’s important to seek medical advice if you suspect you may have either of these conditions. Treatment can involve medication, lifestyle changes, and wearing compression stockings or other support devices. Surgery may also be necessary in severe cases or when other treatments have been unsuccessful.

Living with Venous Insufficiency

Venous insufficiency can be a long-term condition, and it’s important to take steps to manage the condition. This includes regular exercise, maintaining a healthy lifestyle and weight, and wearing the appropriate support garments. It’s also important to recognize the signs and symptoms of blood clots, and seek medical attention immediately if you suspect you may be developing them.


Venous insufficiency is a condition that can lead to various health complications, including an increased risk of developing blood clots. It’s important to familiarize yourself with the symptoms of venous insufficiency, and to seek medical advice if you suspect you may have the condition. There are a variety of treatments and lifestyle changes that can help to manage the condition and reduce the risk of health complications.
