Fibrinogen is a glycoprotein, synthesized and secreted by liver cells, and is mainly involved in the process of coagulation and hemostasis in the organism. Usually, the presence of low fibrinogen during the examination of coagulation function may be a manifestation of abnormal liver function or abnormal coagulation function: 1. Abnormal liver function: When patients have abnormal liver function, it will affect the synthesis and secretion of fibrinogen, resulting in low fibrinogen content. In severe cases, patients may have a tendency to bleed, such as patients with severe hepatitis and severe cirrhosis; 2. Abnormal coagulation function: When patients have abnormal coagulation function, a large amount of fibrinogen in the body will aggregate and participate in the process of coagulation, which will lead to a lower fibrinogen content. It is recommended to check the level of D-dimer in the blood. If the D-dimer is elevated and the patient has an infectious disease, disseminated intravascular coagulation may occur. Low fibrinogen can also be caused by congenital hypofibrinogenemia, shock, hemorrhage, etc. The cause of this condition needs to be determined in conjunction with other laboratory tests, and then targeted treatment should be given. When fibrinogen is low, you should pay attention to a balanced diet, replenish nutrition, and eat more fiber-rich fruits and vegetables.
