What is capillary leak syndrome?

Capillary leak syndrome happens when plasma (the liquid part of your blood) leaks out of tiny blood vessels (capillaries). The fluid leaks into muscles, tissues, organs and body cavities (spaces that hold organs).

Capillary leak syndrome attacks, or episodes, can occur several times a year or only once. If capillary leak syndrome isn’t treated promptly, your blood pressure drops rapidly, leading to organ failure and even death.

Though there’s no cure for capillary leak syndrome, it’s important to get prompt medical treatment to manage symptoms. You may be able to prevent future episodes of systemic capillary leak syndrome with regular use of medications or infusions.
