The International Society on Thrombosis and Haemostasis has launched a campaign for World Thrombosis Day 2026. This effort aims to raise awareness of blood clot risks with a specific focus on the unique challenges faced by women.
Why it matters
Blood clots are often misunderstood health threats that demand greater attention. Women face evolving risks related to hormonal changes, pregnancy, and medical care that require proactive education and timely clinical response.
One in four people worldwide die from conditions caused by thrombosis. Meanwhile, pregnant women are approximately five times more likely to develop a blood clot than the general population.
The players
International Society on Thrombosis and Haemostasis
This global medical organization includes more than 21,000 members across more than 120 countries and focuses on the study and treatment of thrombosis.
The details
The campaign provides educational resources to help healthcare professionals and patients better identify risk factors for venous thromboembolism. Data shows that up to 60% of these cases occur during or within 90 days of hospitalization.
Timeline
The International Society on Thrombosis and Haemostasis was founded in 1969.
World Thrombosis Day campaign takes place on October 13, 2026.
Venous thromboembolism cases frequently occur within 90 days of hospitalization.
Health Landscape
This awareness campaign by the International Society on Thrombosis and Haemostasis marks a significant expansion in efforts to address venous thromboembolism. It serves as a coordinated international push to address a major contributor to global mortality rates.
Patients should be aware that hospitalization significantly elevates the risk of blood clots for up to three months. Understanding these risks, especially regarding pregnancy or medical stays, can help individuals engage more effectively with their healthcare providers.
The takeaway
Proactive communication with doctors regarding personal risk factors is essential during periods of hospitalization or pregnancy. Recognizing the early signs of blood clots can lead to faster medical intervention and better long-term health outcomes.
