What diseases cause blood to fail to clot?

Blood failure to coagulate can be associated with diseases such as hemophilia, cirrhosis, and leukemia, which can cause many related symptoms, but further examinations are needed to clarify the specific conditions.

1. Hemophilia: Hemophilia is a recessive genetic disease that can be inherited through the X chromosome and mainly occurs in males. Due to a defect in the coagulation factor gene, patients experience coagulation dysfunction, resulting in blood failure to coagulate.

2. Cirrhosis: If a patient has cirrhosis, due to decreased liver function, the synthesis of coagulation factors decreases, leading to decreased coagulation function. If cirrhosis is too severe, patients may exhibit blood failure to coagulate.

3. Leukemia: Leukemia is a disease caused by malignant proliferation of bone marrow cells. After developing the disease, it causes hematopoietic dysfunction, leading to a decrease in platelet and red blood cell counts, and also affects coagulation factors. Patients may experience blood failure to coagulate, and most patients also suffer from anemia.

Apart from the aforementioned diseases, liver cancer and disseminated intravascular coagulation can also cause related symptoms. Once these diseases occur, medical attention should be sought as soon as possible to avoid life-threatening consequences.
