Hemophilia is a bleeding disorder. This can prevent the body from clotting blood normally and cause excessive bleeding after an injury. There is not enough clotting factor in their blood. Clotting factor is a protein found in the blood that controls bleeding. People with hemophilia do not bleed faster than normal, but may bleed longer. It often affects the head, stomach, joints, knees, elbows and ankles. Symptoms may include lots of deep, large bruising, joint pain and swelling, unexplained bleeding, and blood in the urine. These symptoms can cause a buildup of blood (hematoma), blood clotting, and abnormal bleeding. To cause hemophilia, there is a defect in one of the genes that determines how the body produces blood clotting factor VIII or IX. Say no to plagiarism.

If the gene is defective, the result is hemophilia, unless there is a dominant, normal gene on a corresponding X chromosome. Hemophilia is a sex-linked recessive disorder. If one person is a carrier for hemophilia, but the other is not, there is a 50% chance that their child will have hemophilia (more likely in a boy). If two people carry hemophilia, there is a 100% chance of having it. If there is no carrier of hemophilia in a relationship, there is always a chance that one could have it, even without a family history. When a father has hemophilia but a mother does not, neither son will have hemophilia, but the daughters will carry the hemophilia gene. These types of defects occur more often in men than in women. A woman can only have hemophilia if her father has it or if her mother is a carrier. This is very rare. In women (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disease. There are two main types of hemophilia. Hemophilia A (due to a deficiency of clotting factor VIII) is the most common type of hemophilia. Hemophilia B (due to a deficiency of clotting factor IX) occurs in one in twenty thousand newborns worldwide. Hemophilia A and B are clinically almost identical and are inherited in an X-linked recessive genetic pattern. Depending on the severity of hemophilia, symptoms may be worse or less likely. It can range from normal to severe. Today, treating hemophilia can be very effective. If a clot is treated quickly and effectively, it will help reduce pain in joints, muscles and organs. To treat a clot, the clotting factor that a person with hemophilia lacks is injected into the bloodstream. When enough clotting factor is injected, the bleeding stops. There is no cure yet and they are currently trying to find one. Keep in mind: this is just a sample. Get a personalized article from our expert writers now.

The treatment is given in case of bleeding in a joint, injury to the neck, mouth, tongue, face or eyes, severe pain, swelling, open wound, etc. Acetylsalicylic acid (aspirin) can cause more bleeding, as can..
