Every year on 13 October, World Thrombosis Day brings people around the world together to raise awareness of thrombosis, commonly known as blood clots. The campaign helps people understand the risks, symptoms and prevention of blood clots.
This year, we are once again supporting World Thrombosis Day and helping to share the official campaign’s resources.
The 2026 campaign continues the theme “From Head to Toe, Take Control: Prevent Thrombosis, Protect Your Health.” This year, there is a particular focus on women’s health and blood clots.
Blood clots can affect anyone, but women can face unique risks at different stages of life. Hormonal contraception can affect blood clot risk, as can pregnancy and the postpartum period. Menopause and hormone therapy can also bring different considerations later in life.
Understanding these risks can help women make informed decisions about their health. It can also help people recognise possible warning signs and know when to seek medical advice.
The World Thrombosis Day campaign has introduced new resources for 2026. These include updated patient fact sheets based on the latest research into blood clot risk and prevention. There are dedicated resources covering pregnancy, birth control and menopause. New materials are also available for healthcare professionals.
Another important resource highlighted this year is the ISTH Women’s Health Hub. Developed by the International Society on Thrombosis and Haemostasis (ISTH), the Hub brings together trusted information about blood health in women and girls.
The Hub covers different stages of life, from adolescence through to healthy ageing. It also provides access to the latest research on thrombosis, haemostasis and bleeding disorders in women and girls.
The Hub brings together patient information and resources for healthcare professionals in one place. It also provides access to clinical guidance, training and peer-reviewed research.
World Thrombosis Day is about turning awareness into action. Knowing your personal risk factors is an important first step. Learning to recognise the signs and symptoms of deep vein thrombosis (DVT) and pulmonary embolism (PE) can also help people know when to seek medical attention.
