Long periods of immobility can put people at risk of dangerous blood clots -- yet hibernating bears lie around for months without any problem. Now scientists think they've figured out why.

The researchers hope the insight can eventually lead to new drugs for preventing life-threatening blood clots -- the kind that begin in the legs but can travel to the brain and cause a stroke, or to the...

Researchers have uncovered a serious risk for folks who have an extra X or Y chromosome.

Those with the genetic condition known as supernumerary sex chromosome aneuploidy have a risk for blood clots in a deep vein or lung that's four or five times higher than usual, a new study

Doctors need to be aware that prostate cancer raises a man's risk of serious and potentially deadly blood clots by about 50%, researchers say.

All cancer patients are at increased risk for venous thromboembolism (VTE), a dangerous but treatable blood clot in the veins that is a leading cause of death in cancer patient...

Cancer patients' blood type may play a role in their risk for dangerous blood clots, researchers say.

Cancer and its treatments increase the risk for venous thromboembolism (VTE). That includes de...

COVID-19 increases people's risk of dangerous blood clots and bleeding for months after infection, researchers say.

The new findings suggest that COVID-19 is an independent risk factor for deep vein thrombosis, pulmonary embolism and bleeding.

"Our findings arguably support [treatment] to avoid thrombotic events, especially for high-risk patients, and strengthen the importance of va...

Who hasn't started to watch a new drama series on TV, and suddenly realize that hours have slipped by as they binged on one episode after the next?

Now, a new study suggests that too much binge-watching may raise the risk of life-threatening blood clots in the legs or lungs by 35%.

"Prolonged TV viewing, which involves immobilization, may increase the risk of venous thromboembolism,...

For people suffering from clots in their legs, a new study finds that one of two commonly used blood thinners is safer and more effective than the other.

Venous thromboembolism (VTE) can cause clots to form in the deep veins in the legs, and if one breaks loose it can travel to the lungs and cause breathing problems and even death. In this study, researchers looked at the risks and benefi...
