What Happens When Your Blood Does Not Clot?

Causes and Symptoms of Hemophilia

Hemophilia is a genetic disorder, which is marked by improper blood clotting. In this bleeding disorder, a person suffers from low levels of certain proteins called clotting factors, which aid in the process of blood clotting. There are 13 types of factors that combine with platelets to help in the formation of a blood clot. People who suffer from hemophilia start bleeding due to minor reasons and their blood takes a very long time to clot.

Causes of Hemophilia

Depending on the type, the causes of hemophilia can vary. There are three types of hemophilia, namely hemophilia A, B, and C.

  • Hemophilia A, the most commonly occurring form, is caused by a deficiency of factor VIII.
  • Hemophilia B, also known as Christmas disease, is caused by the lack of factor IX.
  • Hemophilia C, on the other hand, occurs due to the lack of factor XI.


However, hemophilia is a genetic condition, which usually passes down from generation to generation. A defect in the genes, which causes the body to make factors VIII, IX, or XI causes the condition. These particular genes are located in the X-chromosomes and, thus, it makes hemophilia an X-linked recessive disorder.


What are the symptoms of hemophilia?

The intensity of symptoms would depend upon the seriousness of the factor deficiency. A person with a serious deficiency may bleed for no apparent reason, which is also known as spontaneous bleeding.

Some of the symptoms of this bleeding disorder are:

- Blood in the urine and stool
- Large, deep bruises
- Excessive bleeding
- Bleeding gums
- Frequent nosebleeds
- Pain and stiffness in the joints
- Irritability and anxiety
- Severe headaches
- Repeated vomiting
- Neck pain
- Cloudy or foggy vision
- Extreme sleepiness
