According to the World Federation of Hemophilia, one in every 10000 children born worldwide, are born with this disease. But what is it? Let’s take a look at its symptoms causes and types in detail below.

What is Hemophilia?

Hemophilia is a bleeding disorder, which happens when the blood doesn’t clot as it is supposed to. This is an inherited or genetic disorder that takes place when there is a lack of blood protein in the body. The most common sign of this blood disorder is excessive bleeding during the time of an injury. While small cuts and bruises are not a problem, what can be troublesome is excessive internal bleeding, in your knees, elbows, and ankles. It can also become life-threatening by causing damage to your internal organs and tissues.

This disorder has mainly two types, namely hemophilia A and B. Since this disorder has an X-linked genetic pattern, men are most commonly affected by it, while women become the carriers. In some cases, there can be an occurrence of hemophilia C; it doesn’t happen in the X-linked pattern and consequently can affect both the sexes.


There are many symptoms of hemophilia and they may vary as per the scale of your condition, from mild to severe.

  • Excessive bleeding from cuts and wounds
  • Excessive bleeding after vaccinations
  • Irritability in infants
  • Deep bruises
  • Swelling of the joints
  • Blood while urinating or passing a stool

Those suffering from a severe form of hemophilia may experience bleeding in the brain. Although it happens very rarely, it can cause serious complications, such as the following:

  • Double vision
  • Headache
  • Lethargy or excessive tiredness
  • Frequent vomiting
  • Seizures


This disorder is a result of a genetic mutation, which causes the protein cells in your body to impair the blood clotting process. The blood clotting process involves a complex mechanism of 13 proteins, medically termed through factor I to XIII.

  • Hemophilia A is caused by a deficiency of factor VIII (factor 8)
  • Hemophilia B is caused by a deficiency of factor IX (factor 9).
  • In rare to rare cases, there can be a hemophilia C which results from the deficiency of factor XI (factor 11).

There is no cure for this condition, but proper diagnosis and treatment can help.
