A thrombus is an abnormal bl00d clot that forms inside a blood vessel. Blood clotting is necessary when the body needs to stop bleeding, but when a clot forms inside a vein or artery without injury, it can block blood flow and become dangerous.
Possible complications include:
- Pulmonary embolism, when a clot travels to the lungs
- Stroke, when bl00d flow to the brain is blocked
- Heart att3ck, when a clot blocks bl00d flow to the heart
- Deep vein thrombosis, when a clot forms in a deep vein, often in the leg
Even one untreated clot can become life-threatening, which is why medicines associated with higher clotting risk are taken seriously by health regulators.
