Swelling in Feet Due to Vein Problems — Expert Treatment

Swelling in Feet and Ankles — A Venous Problem

Swelling (oedema) in the feet and ankles is one of the most common complaints seen at Dr. Raja's Vein & Intervention Clinic in Bathinda. When caused by vein problems — specifically venous reflux from varicose veins — the swelling is typically:

• Worse toward the evening after prolonged standing
• Better in the morning after overnight elevation
• Associated with heavy, aching legs
• Often accompanied by visible veins on legs
• May have a brownish skin discoloration above the ankle

This type of swelling is called venous oedema and is directly caused by the increased pressure within the diseased leg veins forcing fluid out into the surrounding tissues.

Why Do Vein Problems Cause Swelling in Feet?

Healthy leg veins return blood from the feet and legs back to the heart. When the valves inside these veins fail (venous reflux), blood pools in the lower leg veins. The resulting high venous pressure forces fluid and proteins out of the capillaries into the surrounding soft tissues — causing oedema (swelling) in the feet, ankles and lower legs.

The calf muscle pump (which pushes blood upward during walking) becomes insufficient to overcome this high venous pressure in severe reflux. This is why prolonged standing makes the swelling worse and elevation provides temporary relief.

Causes of Venous Foot and Ankle Swelling

• Varicose veins with venous reflux — the most common vein-related cause
• Chronic venous insufficiency (CVI) — advanced venous disease
• Post-thrombotic syndrome — residual venous damage after DVT
• Perforator vein incompetence — leaking perforating veins between deep and superficial systems
• Pelvic vein congestion — venous reflux originating from pelvic veins (especially in women)

How Is Vein-Related Swelling Diagnosed?

A Colour Doppler ultrasound of the leg veins is the key diagnostic test. It identifies:

• Which veins are refluxing and how severely
• Whether deep or superficial veins are involved
• The extent of venous disease
• Whether any DVT or post-thrombotic changes are present

Blood tests and other investigations may be requested to exclude kidney, liver or heart causes of swelling.

Treatment for Vein-Caused Swelling in Feet

Short-Term Management

• Compression stockings (knee-length, 20-40 mmHg) reduce swelling by 50-80%
• Regular leg elevation above heart level — 20-30 minutes, 3-4 times daily
• Regular walking to activate calf muscle pump
• Reducing prolonged standing or sitting

Definitive Treatment — Treating the Veins

The most effective and lasting solution for vein-related swelling is to treat the underlying varicose veins:

• Endovenous Laser Ablation (EVLA) — permanently closes the refluxing vein
• MOCA — mechanochemical closure of varicose veins
• Foam Sclerotherapy — for smaller varicose veins

After successful vein treatment, most patients experience significant reduction in leg swelling within 4-8 weeks as venous pressure normalises. Many patients who have worn compression stockings for years find they no longer need them after treatment.

Visible Veins on Foot

Visible veins on the foot dorsum are often normal — the dorsal veins of the foot are naturally prominent in most people, especially with low body fat. However, when foot vein prominence is associated with varicose veins on the ankles and feet, swelling and skin changes, it indicates venous hypertension that needs treatment.
