What Is Chronic Venous Insufficiency?

Have you ever noticed someone’s legs looking swollen, or seen veins that seem twisted and bulging? While many things can cause these changes, one common reason is a condition called chronic venous insufficiency (often shortened to CVI). But what is CVI, what causes it, and how does it affect people’s health? Let’s take a closer look.

How Do Healthy Veins Work?

First, a quick trip inside the body! Your arteries are blood vessels that move blood away from your heart. Your veins, on the other hand, carry blood back to your heart after your body’s cells have used the oxygen and nutrients they need. In your legs, veins work extra hard, pushing blood upward – often against gravity – back toward the heart.

To help with this tough job, veins have tiny one-way valves inside them. These valves act like little doors: they open to let blood flow up, then quickly close to stop it from flowing backward.

What Happens in Chronic Venous Insufficiency?

Chronic venous insufficiency happens when those valves in the leg veins stop working well. When this happens, some blood leaks backward and pools in the veins instead of moving up to the heart. Over time, this extra pressure and pooling can cause:

Swelling in the legs and ankles
Aching, heaviness, or tiredness in the legs
Itchy or irritated skin
Varicose veins (twisted, bulging veins)
Skin changes or sores (ulcers) that are slow to heal

CVI can affect people of any age, but it’s more common in older adults or those who stand or sit for long periods. It can also happen after blood clots in the leg (a condition known as deep vein thrombosis), or as a result of injury.

What Causes CVI?

There are several possible causes:

Weak or damaged vein valves: Sometimes these are weak from birth; other times, they get damaged over time.
Blood clots: These can block or damage veins.
Obesity: Extra weight puts more pressure on leg veins.
Pregnancy: The growing baby and hormones can affect veins.
Standing or sitting for long times: This makes it harder for blood to flow back to the heart.

How Is It Diagnosed and Treated?

Doctors diagnose CVI by asking about symptoms, doing a physical exam, and sometimes using an ultrasound scan to see how blood flows in the veins.

Treatment focuses on improving blood flow and relieving symptoms. Common strategies include:

Wearing compression stockings: These gently squeeze the legs, helping blood move upward.
Raising the legs: Putting legs up while sitting or resting can reduce swelling and remove some of the gravity-related pressures.
Exercise: Walking and moving help the muscles push blood through the veins.
Medication or procedures: In some cases, medicines or simple surgeries may be needed to treat damaged veins or ulcers.

The good news is that with care and lifestyle changes, many people with CVI can manage their symptoms and keep their legs healthy.

Fascinating Facts About Chronic Venous Insufficiency

It’s common: Millions of people worldwide have some degree of CVI, especially as they get older.
Not just cosmetic: Varicose veins may look curious and often they’re completely benign, but they can signal a real health problem and should be inspected by a healthcare professional.
More common in women: Hormonal changes (like those during pregnancy) may play a role.
Exercise helps: Calf muscles act as a “second heart” by pumping blood back to the heart with every step! Keep tracking those steps, as you could be working wonders for your circulatory health!
Can be prevented: Staying active, keeping a healthy weight, and not sitting or standing too long can lower your risk.
