Fibrinogen is an item of coagulation function, and a mild elevation is usually not of great pathological significance. Especially for some pregnant women and patients in acute inflammatory phase, mild elevation is considered normal and patients only need to actively treat the primary disease. Fibrinogen is a protein synthesized by the liver, which has coagulation function and is generally involved in the process of coagulation. Therefore, for patients with poor liver function, it can cause patients with reduced fibrinogen. In this case the patient considers whether the underlying pathology of the liver, such as whether the patient has viral hepatitis, and whether there is long-term chronic inflammation and the possibility of chronic hepatitis. In addition, for acute hepatitis and myocardial infarction, as well as some patients with rheumatism, mild elevation of fibrin may also occur. Patients are advised to eat a diet rich in vegetables and fruits, as well as an appropriate amount of vitamin D3 and other trace elements, and to eat as little animal fat and high-fat food as possible.
