What you should know about Deep Vein Thrombosis (DVT)
If you’ve ever worried about a blood clot forming in your leg, you’re not alone. DVT in lower leg (deep vein thrombosis) happens when a blood clot develops in the deep veins, often in the calf. This condition is more common than most people think and can turn serious if not treated early. In this guide, we’ll break down the symptoms, causes, treatment, and recovery tips in plain, everyday language, so you know what to look for and when to seek help.
What is Deep Vein Thrombosis (DVT) in the Lower Leg?

Deep vein thrombosis in leg is a condition where blood clots form in the deep veins, usually in the calf or thigh. These clots can restrict blood flow and, in severe cases, break loose and travel to the lungs causing a life-threatening pulmonary embolism.
Doctors estimate that up to 900,000 people in the U.S. develop DVT each year (CDC). Many go undiagnosed because the symptoms can be mistaken for muscle pain or injury. That’s why understanding the warning signs is so important.
Common Causes and Risk Factors – Symptoms of DVT in the Lower Leg
Causes & Risk Factors
DVT can develop for several reasons:
-
Prolonged sitting or standing – like long flights or desk jobs.
-
Injury or surgery – especially involving the leg or hip.
-
Medical conditions – cancer, clotting disorders, or heart disease.
-
Lifestyle factors – smoking, obesity, or dehydration.
Age – risk increases after 60, but younger people aren’t immune.

Complications of Untreated DVT
Ignoring a clot can be dangerous. If untreated, DVT can lead to:
-
Pulmonary embolism (PE): When a clot travels to the lungs, causing chest pain, shortness of breath, or even sudden collapse.
-
Post-thrombotic syndrome: Chronic swelling, skin changes, and pain in the leg.
-
Permanent vein damage: Making you more likely to get future clots.
According to the National Blood Clot Alliance, 1 in 3 people with DVT will have long-term complications if not treated properly.
