Top 5 Reasons Your Legs are Swollen!

Do you wake up with normal feet but find them swollen by evening? Or perhaps one leg is suddenly much larger than the other? Leg swelling (Edema) is a common complaint, but it is often a signal that something deeper is happening in your vascular system.

In his latest video, Dr. Rohit Agarwal, Director of Interventional Radiology at Medanta Lucknow, breaks down why your legs might be swelling and, more importantly, which signs indicate a medical emergency.

1. Deep Vein Thrombosis (DVT): The Silent Danger

If the swelling is sudden and affects only one leg, it could be DVT—a blood clot in the deep veins. This is a medical emergency because the clot can travel to the lungs (Pulmonary Embolism). DVT often presents with pain, redness, and warmth in the affected area. If you suspect a clot, learn more about DVT treatment in Lucknow using minimally invasive techniques.

2. Varicose Veins & Venous Insufficiency

This is the most common vascular cause of chronic swelling. When the valves in your leg veins weaken, blood "pools" instead of flowing back to the heart. This leads to heavy legs, visible purple veins, and swelling that worsens after standing for long periods. Today, varicose veins treatment without surgery is available through RF ablation and laser techniques.

3. Heart-Related Issues (Congestive Heart Failure)

If your heart isn't pumping efficiently, fluid can back up into your legs. This type of swelling is usually bilateral (affects both legs) and may be accompanied by shortness of breath when lying flat.

4. Kidney or Liver Disease

Systemic issues like kidney failure or liver cirrhosis can affect how your body regulates fluids and proteins. If your body loses protein through the kidneys, fluid naturally leaks out of the blood vessels and into the tissues of your legs and feet.

5. Lymphedema & Localized Inflammation

A blockage in your lymphatic system or localized issues like infections (cellulitis) or trauma can also cause significant swelling. Lymphedema is often chronic and requires specialized management.

"Don't ignore the signs. A simple ultrasound or clinical check can distinguish between a minor fluid issue and a life-threatening clot." — Dr. Rohit Agarwal
