Fibrinogen is a protein produced by the liver. It’s involved in blood clots and increases in response to inflammation. A normal fibrinogen level is important for healthy blood clotting. Low fibrinogen can increase the risk for excessive bleeding. Since fibrinogen influences blood viscosity, elevations in fibrinogen can be very problematic as it can slow blood flow and promote the formation of blood clots in the blood vessels.
High fibrinogen can increase the risk for dangerous blood clots such as deep vein thrombosis or pulmonary embolism. Elevations in fibrinogen have been consistently shown to be a predictor of cardiovascular disease including hypertension, heart attacks and strokes. In fact, approximately 80% of strokes are caused by blood clots.
