Why Do Tall People Have A Higher Risk of Blood Clots?

Being tall may increase the risk of blood clots in the leg veins or lungs in both men and women, according to a new Swedish study that examined government health records of nearly 3 million people.

While other research has noted the correlation, this study is unique because it only included siblings, minimizing the chance that environmental factors affected the results.tall woman

“Socioeconomic factors like education and poverty can confound results. One way to adjust for that is a sibling design because they share the same socioeconomic background,” said the study’s lead researcher Bengt Zöller, M.D., of Lund University and Skåne University Hospital in Sweden.

Researchers looked at rates of a condition called venous thromboembolism, in which a blood clot occurs in the deep veins of the leg, known as deep vein thrombosis, or in one or more arteries in the lungs, known as a pulmonary embolism.
