Hemophilia symptoms vary, depending on the degree of blood clotting factor (coagulation factor) deficiency and they also depend on the nature of any injury.
Three levels of hemophilia are recognized, according to the level of clotting factor amounts in the blood. These are often expressed as percentages of normal:
People with inherited mild hemophilia may not have any symptoms until an event occurs which wounds the skin or tissue, such as a dental procedure or surgery, and results in prolonged bleeding. In societies where male circumcision is carried out soon after birth, mild hemophilia will be detected earlier. Joint bleeding is uncommon.
Those with inherited moderate hemophilia will be noticeable early on. The child will bruise easily and may also experience internal bleeding symptoms, especially around the joints, and after a blow or a fall. Bleeding that occurs inside a joint is usually referred to as a joint bleed.
Symptoms of a joint bleed:
If left untreated, the patient may eventually experience:
Joint bleeds most commonly affect the:
Any surgical intervention, circumcision, dental procedure or injury will result in prolonged bleeding in a person with hemophilia.
Symptoms are similar to those found in moderate hemophilia, but occur more frequently and are usually more severe.
A child with severe hemophilia will often bleed for no apparent reason, often referred to as spontaneous bleeding. Most commonly, in early childhood from about 18 months of age, the nose or mouth start to bleed or apparently spontaneous bruises appear, particularly on the legs. Parents are sometimes suspected of causing non-accidental injury (deliberate harm) to their children.
Symptoms of hemophilia type bleeding may include:
About 1 in every 30 patients with hemophilia will have intracranial hemorrhage at least once during their lives. This should be treated as a medical emergency. Spontaneous intracranial hemorrhage is rare and in many cases bleeding inside the skull will be the result of a blow to the head.
Symptoms of intracranial hemorrhage include:
Prenatal testing - if a pregnant woman has a history of hemophilia, a hemophilia gene test can be done during pregnancy. A sample of placenta is removed from the uterus and tested. This test is known as a CVS (chorionic villus sampling) test.
Blood test - if a doctor suspects a child may have hemophilia a blood test can determine whether the patient has hemophilia A or B, and how severe it is. Blood tests can be performed from the time of birth onwards.
