Protein C Deficiency

Protein C Deficiency is a condition where your body either doesn't produce enough of a natural protein called Protein C, or the Protein C you have isn't working correctly. Protein C is made in your liver and plays a vital role in your blood clotting system, acting as a natural anticoagulant (blood thinner) to prevent excessive clotting. Its main job is to help maintain a healthy balance, ensuring blood clots form when needed (like to stop bleeding) but don't form unnecessarily or become dangerously large. When you have a deficiency, this balance is disrupted, increasing your risk of developing potentially harmful blood clots. This condition can be inherited (passed down through families) or acquired. Inherited Protein C Deficiency is the most common type, meaning you were born with a genetic change that affects your body's ability to produce or use Protein C. Acquired deficiency can develop due to other medical conditions like severe liver disease, certain infections (sepsis), or even during the initial treatment with some anticoagulant medications like warfarin. Lab tests for Protein C are crucial for diagnosis, especially if you have a personal or family history of unexplained blood clots, have experienced recurrent miscarriages, or are being evaluated for your risk of clotting. Identifying this deficiency helps your doctor understand your individual clotting risk and guide appropriate management, which might include preventive measures or specific treatments to reduce your risk of serious complications from blood clots.
