Why do blood clots form?
Bleeding disorders often develop when the blood can’t clot properly. For blood to clot, your body needs blood proteins called clotting factors and blood cells called platelets. Normally, platelets clump together to form a plug at the site of a damaged or injured blood vessel. The clotting factors then come together to form a fibrin clot. This keeps the platelets in place and prevents blood from flowing out of the blood vessel.
What is a bleeding time test?
a bleeding time test, which determines how quickly your blood clots to prevent bleeding
What is hemophilia A and B?
Hemophilia A and B are conditions that occur when there are low levels of clotting factors in your blood. It causes heavy or unusual bleeding into the joints. Though hemophilia is rare, it can have life-threatening complications.
How to treat bleeding disorders?
Some bleeding disorders may be treated with topical products or nasal sprays. Other disorders, including hemophilia, can be treated with factor replacement therapy. This involves injecting clotting factor concentrates into your bloodstream. These injections can prevent or control excessive bleeding.
What is the most common inherited bleeding disorder?
Von Willebrand’s disease is the most common inherited bleeding disorder. It develops when the blood lacks von Willebrand factor, which helps the blood to clot.
What is a blood transfusion?
A blood transfusion replaces any lost blood with blood taken from a donor. The donor blood has to match your blood type to prevent complications. This procedure can only be done in the hospital.
Why is it important to call your doctor right away?
It’s important to call your doctor right away if you have any symptoms of a bleeding disorder. Getting prompt treatment will help prevent any potential complications.
How many people have Von Willebrand disease?
It is estimated that 1% of the population has some form of Von Willebrand disease. VWD is also inherited but both men and women can be equally affected. The amount of bleeding can vary greatly depending on what type of VWD a person inherits.
What is the most well known bleeding disorder?
Types. Hemophilia: Probably the most well known bleeding disorder is hemophilia. People with hemophilia are missing one of their coagulation factors. The name of their type of hemophilia depends on what factor is missing.
What is the purpose of platelet transfusion?
Platelet transfusions: If the platelet count is low or the platelets do not function correctly, a platelet transfusion may be given to prevent/treat bleeding. Fresh frozen plasma: Coagulation factors are found in the plasma (liquid component of blood).
What happens if your platelets are low?
Platelet function disorders: In addition to low platelet numbers causing bleeding, if the platelets do not function properly, bleeding may occur. 6
What is the second part of the blood cycle called?
One part of the process involves the platelets, a type of blood cell. The second part is found in the liquid portion of blood, called coagulation factors. People sometimes refer to people with bleeding disorders as “free bleeders.”.
What is excessive bleeding after a needle stick?
Excessive menstrual periods referred to as menorrhagia as well as excessive bleeding postpartum (after delivery) Prolonged bleeding after a needle stick (blood draw or injection like a vaccine) Excessive bleeding during or after surgery that requires additional efforts to stop bleeding. Large palpable bruises.
What happens if the liver is not functioning properly?
Liver disease: When the liver is not functioning properly, it is unable to produce coagulation factors. Without these factors, patients can have significant bleeding. 4
What is a rare disease?
In the US, a rare disease or disorder is defined as one that affects fewer than 200,000 people, making hemophilia A and B, and still less prevalent factor deficiencies such as I, II, V, VII, X, XI, XII and XIII, rare disorders. These very rare factor deficiencies, from factor XIII deficiency, the rarest, occurring in an estimated 1 out of 5 million people, to factor XI deficiency, occurring in about 1 out of 100,000, were all discovered and identified in the 20th century. The majority of these conditions were only identified within the last 60-70 years. Here you will find information on how factor deficiencies I, II, V, VII, X, XI, XII and XIII are inherited identified and managed.
What is the genetic cause of von Willebrand disease?
Von Willebrand Disease. Von Willebrand disease (VWD) is a genetic disorder caused by missing or defective von Willebrand factor (VWF), a clotting protein. VWF binds factor VIII, a key clotting protein, and platelets in blood vessel walls, which help form a platelet plug during the clotting process.
What is the genetic disorder of hemophilia?
Hemophilia A, also called factor VIII (FVIII) deficiency or classic hemophilia, is a genetic disorder caused by missing or defective factor VIII, a clotting protein. Although it is passed down from parents to children, about 1/3 of cases are caused by a spontaneous mutation, a change in a gene.
What is the most common bleeding disorder in the US?
The condition is named after Finnish physician Erik von Willebrand, a who first described it in the 1920s. VWD is the most common bleeding disorder, affecting up to 1% of the US population. It is carried on chromosome 12 and occurs equally in men and women.
How rare is factor XIII?
These very rare factor deficiencies, from factor XIII deficiency, the rarest, occurring in an estimated 1 out of 5 million people, to factor XI deficiency, occurring in about 1 out of 100,000, were all discovered and identified in the 20th century.
How many people have hemophilia?
According to the US Centers for Disease Control and Prevention, hemophilia occurs in approximately 1 in 5,000 live births. There are about 20,000 people with hemophilia in the US. All races and ethnic groups are affected. Hemophilia A is four times as common as hemophilia B while more than half of patients with hemophilia A have the severe form of hemophilia.
What is the cause of vitamin K deficiency?
Vitamin K deficiency causes a mild bleeding disorder due to a deficiency of clotting factors VII, IX, X and prothrombin (factor II). The liver utilizes vitamin K to synthesize these clotting factors. Factor I deficiency is due to a lack (afibrinogenemia), deficiency (hypofibrinogenemia) or defective functioning (dysfibrinogenemia) of fibrinogen.
What is the most common bleeding disorder in von Willebrand disease?
The two most common bleeding disorders in von Willebrand disease and hemophilia. von Willebrand disease (vWD) is a deficiency or defect of von Willebrand factor (vWF) which is an important carrier of clotting factor VIII and helps platelets adhere to the site of the blood vessel damage. The different types of von Willebrand disease include :
What are the different types of hemophilia?
Hemophilia is a deficiency of one of the clotting factors involved in the coagulation cascade that eventually leads to the formation of a blood clot. Hemophilia A and B mainly affects males. There are three different types : 1 Hemophilia A where there is a deficiency in factor VII 2 Hemophilia B where there is a deficiency in factor IX 3 Hemophilia C where there is a deficiency in factor XI
What is a bleeding disorder?
What are bleeding disorders? A bleeding disorder is any impairment in the process of hemostasis (mechanism to prevent blood loss) thereby leading to profuse and/or prolonged bleeding. Most of these bleeding disorders involve one or more defects in the phases or components of hemostasis.
How many phases of hemostasis are there?
There are four distinct phases in hemostasiswhich is geared to stop blood loss.
What happens when blood vessels are damaged?
First the damaged blood vessel narrows ( vasoconstriction) to reduce the blood flow and therefore blood loss. This happens almost immediately once the blood vessel is damaged. Second the platelets in the blood (small particles of larger cells) adheres to the lining of the damaged blood vessel and stick to each other to plug the site of blood loss ...
Why is the entire process carefully coordinated by the body?
The entire process is carefully coordinated by the body to ensure that the sequence of events will stop the blood loss as rapidly as possible. In some instances where there is a severe injury with excessive blood loss, these mechanisms are ineffective and medical attention is necessary.
Why does capillary bleeding happen?
Capillary bleeding typically happens due to injury to the skin, and it is much more common than the other types. Instead of spurting out, as in arterial bleeding, or flowing out, as in venous bleeding, it oozes from the damaged body part.
What are the different types of bleeds?
There are three main types of bleeding: arterial, venous, and capillary bleeding. Arterial bleeding occurs in the arteries, which transport blood from the heart to the body. Venous bleeding happens in the veins, which carry blood back to the heart. Capillary bleeding takes place in the capillaries, which are tiny blood vessels that connect the arteries to the veins.
What are the three types of bleeding?
These three types of bleeding, or hemorrhaging, differ not only in location but also in how they flow and their severity. Specifically, arterial bleeding comes out in spurts, venous bleeding flows steadily, and capillary bleeding trickles from the body.
What is the final step in a sterile dressing?
The final step is to apply pressure with a latex-gloved hand and sterile dressing. Typically, pressure is sufficient to control the bleeding, and the additional steps that a doctor may use to stop arterial or venous bleeding are not necessary.
What to do if you have a bleeding wound?
The initial step is to put pressure over the wound causing the bleeding with a latex-gloved hand and sterile gauze. It is also important to contact an emergency number to get medical help.
Why is capillary bleeding the easiest to control?
Not only is capillary bleeding the least severe, but it is also the easiest to control because it comes from blood vessels on the surface rather than from deep inside the body.
What is external bleeding?
External bleeding refers to bleeding that flows out of the body. Examples include nosebleeds and bleeding from a minor skin cut.
