One leg swollen more than the other - blood clot?

Swelling in one leg more than the other can be a symptom of deep vein thrombosis (DVT). DVT occurs when a blood clot forms in a deep vein, often in the legs, and can lead to serious complications if not addressed. Clinically, DVT is often associated with unilateral swelling, meaning one leg is noticeably larger than the other, along with symptoms like warmth, tenderness, and sometimes redness. This is due to the obstruction of blood flow caused by the clot.

Medical literature highlights that certain risk factors increase the likelihood of DVT, including prolonged immobility, recent surgery, and a history of clotting disorders. Clinicians also typically assess whether there is accompanying pain or a history of recent travel, as these can raise suspicion for DVT.

It's important to remember that other conditions, such as muscle strains or infections, can also cause leg swelling. Standard evaluation for suspected DVT might involve imaging tests like an ultrasound to confirm the presence of a clot. Anyone with concerns about leg swelling or potential DVT should discuss their specific situation with their healthcare provider.
