Understanding Venous Insufficiency
Venous insufficiency is a condition where your leg veins struggle to send blood back to your heart. It can be mild, or it can be severe, and the longer it goes unaddressed the higher the risk of complications.

The Cause
What Is Venous Insufficiency?
Valves inside your leg veins are meant to keep blood moving in one direction, toward your heart. When they are damaged or weakened, blood flows backward and pools in your legs.
Valve damage comes from a clot in a deep vein, extra weight, pregnancy, long hours sitting or standing, or smoking. Some people are born with faulty valves. It can affect deep veins, surface veins, or the perforating veins that connect them.
Treatment
Treatment Options for Venous Insufficiency
Most people start with compression and lifestyle changes. When that is not enough, closing the damaged vein is a short outpatient procedure.
- Compression Therapy
- Regular Exercise
- Healthy Weight
- Leg Elevation
- Thermal Ablation
- Sclerotherapy
When to Act
When to See a Doctor for Venous Insufficiency
A venous duplex ultrasound settles it quickly. Book an evaluation if you notice any of these.
- Persistent leg pain and swelling after standing
- Aching, cramping or heaviness in your legs
- Skin changes: itching, dryness or hardening
- Reddish-brown discoloration or open sores


Don't Wait
The Reason You Don't Want to Wait
Chronic venous insufficiency is graded C0 to C6. It only moves in one direction without treatment:
- C1: spider veins or reticular veins
- C2: varicose veins
- C3: swelling, with no skin changes yet
- C4: pigmentation, eczema or hardened skin
- C5: a venous ulcer that has healed
- C6: an active, open venous ulcer
Catching it at C1 or C2 means compression and a short outpatient procedure. Waiting for C5 or C6 means wound care that can take months.
