Understanding Hemophilia

Hemophilia is a rare genetic bleeding disorder where the blood doesn’t clot properly, leading to prolonged bleeding after injury or surgery.

What is Hemophilia?

Hemophilia is an inherited bleeding disorder in which the blood does not clot properly. This can lead to spontaneous bleeding as well as bleeding following injuries or surgery. Blood contains proteins called clotting factors that help stop bleeding. People with hemophilia have low levels of either factor VIII or factor IX.

Genetic Basis

Hemophilia is caused by mutations in genes that encode proteins essential for blood clotting. It’s typically inherited in an X-linked recessive pattern, mainly affecting males.

Diagnosis

Hemophilia is diagnosed through blood tests that measure the level and activity of clotting factors. Early diagnosis is critical for managing the condition and preventing complications.

Types of Hemophilia

Hemophilia A

The most common type, caused by a deficiency in clotting factor VIII. It affects approximately 1 in 5,000 male births.

Hemophilia B

Also known as Christmas disease, caused by a deficiency in clotting factor IX. It affects approximately 1 in 25,000 male births.

 

Hemophilia C

A rarer form caused by a deficiency in clotting factor XI. Unlike A and B, it affects both males and females equally.
