Russian doctor warns daily habits can raise blood clot risk

Russian hematologist Radion Tarnovsky has warned that certain daily habits can increase the risk of developing blood clots, highlighting inactivity as a leading factor.

In an interview with Russia's Lenta news site, Tarnovsky explained that prolonged inactivity—such as sitting for hours during travel, after surgery, or following injuries—raises the likelihood of venous thrombosis.

Tarnovsky added that smoking, obesity, and lack of physical activity, along with factors such as aging, a history of clots, cancer, pregnancy, and the use of certain hormonal medications, all contribute to a higher risk.

The doctor also noted that dehydration and insufficient fluid intake are causes of blood clots. He stressed there is no universal rule for daily water intake, as hydration needs depend on body weight, temperature, activity level, diet, health status, and medications used.

To prevent blood clots, Tarnovsky advised increasing daily activity, reducing foods high in fat and carbohydrates, and avoiding smoking and alcoholic beverages that harm heart and vascular health.
