What Causes Blood Clots?

Blood clots, or thrombi, are crucial for stopping bleeding but can be dangerous if they form without injury. They occur when blood vessels are damaged or blood flow is restricted, leading to clot formation. Clots can block blood flow, causing conditions like heart attacks or strokes. Risks include genetic factors, diseases, and lifestyle issues such as smoking and obesity. Recognizing symptoms like leg pain or chest pressure is essential for prompt treatment.
