Deep Vein Thrombosis (DVT)
Deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein, most often in the legs. This can restrict blood flow and cause pain or swelling — and in some cases, the clot may travel to the lungs, leading to a serious condition known as a pulmonary embolism. Prompt diagnosis and treatment are essential to prevent complications and protect your vascular health.
Symptoms
Common Signs and Symptoms
Swelling in one or both legs
Pain or tenderness, often starting in the calf
Warmth or redness of the skin over the affected vein
Leg fatigue or a heavy sensation
In some cases, DVT can occur without obvious symptoms
Risk Factors
Factors that may increase your risk of developing DVT include:
Prolonged periods of sitting or immobility (e.g., long flights or bed rest)
Surgery or trauma, particularly to the legs or pelvis
Family or personal history of blood clots
Hormonal therapy, pregnancy, or recent childbirth
