an inherited bleeding disorder caused by low levels, or absence of, a blood protein that is essential for clotting; hemophilia A is caused by a lack of the blood clotting protein factor VIII; hemophilia B is caused by a deficiency of factor IX.
a hereditary blood coagulation disorder that is manifested almost exclusively in males
An inherited disease that prevents the normal clotting of blood.
is a thinning of the blood which prevents it from coagulating.
Gk. haima, blood + philios, friendly] A group of hereditary disorders characterized by failure of the blood to clot and consequent excessive bleeding from even minor wounds.
The reduced ability of the blood to clot.
A hereditary disease characterized by a prolonged coagulation time and repeated hemorrhages, occurring only in males and transmitted only by females and affected males. The cause is a deficiency in a plasma factor (antihemophilic globulin or thromboplastinogen) resulting in a defect in thromboplastic activity.
A hereditary, plasma-coagulation disorder, principally affecting males but transmitted by females, and characterized by excessive, sometimes spontaneous, bleeding.
A sex-linked hereditary blood defect (primarily of males) characterized by delayed clotting of the blood and consequent difficulty in controlling hemorrhage even after minor injuries.
A term used to describe bleeding disorders caused by low levels of factor VIII or IX (hemophilia A and B). The term can also be used more broadly to describe the family of bleeding disorders, including VWD.
HEMOPHILIA is a blood-related condition that people are born with. People with HEMOPHILIA lack something called a "clotting factor" in their blood. Once a person with HEMOPHILIA gets cut, he or she will bleed for a very long time. Before hospitals screened donated BLOOD for HIV, HEMOPHILIACS (people with HEMOPHILIA) were at a higher risk for HIV because they tend to get BLOOD TRANSFUSIONS more than people without HEMOPHILIA.
Either of two X-linked bleeding disorders, referred to as Hemophilia A and Hemophilia B. The latter is also known as “Christmas Disease.
the blood lacks coagulating factors, causing a strong tendency to bleed, and difficulty in getting the bleeding to stop. hepatitis – inflammation of the liver. This can result from a variety of causes including infections (particularly viral), drugs, autoimmunity and genetics. The liver stores and filters blood, secretes bile, converts sugars, processes fat, produces proteins which help to control blood volume, and produces some of the clotting factors.
A genetic blood disorder in which the blood fails to clot normally. This disorder is hereditary and is due to a deficiency in or an abnormality of one of the clotting factors. Hemophilia is manifested almost exclusively in males.
congenital tendency to uncontrolled bleeding; usually affects males and is transmitted from mother to son
a hereditary condition manifested by a tendency to uncontrollable hemorrhage with or without injury
an inherited disease that prevents blood from clotting
A hereditary deficiency of coagulation Factor VIII which results in various repeating bleedings. It affects only males.
An inherited bleeding disorder characterized by the absence or decreased levels of certain blood clotting proteins.
Hereditary disease in which blood fails to clot at normal speed, due to absence of Factor VIII.
(Factor VIII, IX, X, XII) – an inherited abnormality of the blood appearing only in the male population. The coagulation time of the blood is prolonged, despite the fact that bleeding time, prothrombin time, platelet count and tourniquet tests are normal. In the classical hemophilia (caused by a deficiency in Factor VIII) severe and prolonged hemorrhages can follow trivial injuries. This can pose a management problem during elective-type surgeries.
a bleeding disorder in which a clotting factor (usually factor VIII or IX) is missing or does not function normally. Most people with hemophilia are male.
An inherited blood disorder caused by a defect in the clotting ability of blood cells. People with hemophilia bleed profusely and easily, either spontaneously and/or with injury.
A largely inherited clotting disorder that occurs almost exclusively in males. The disorder delays coagulation, making bleeding difficult to control.
A bleeding disorder in which a specific clotting factor protein, namely factor VIII or IX, is missing or does not function normally.
A hereditary blood disorder that prevents blood from clotting properly.
Term describing the condition in which patients have an abnormal tendency to bleed because they are unable to adequately form clots.
Hereditary blood disease characterized by prolonged coagulation time. Results in failure of blood to clot and abnormal bleeding.
A genetic disease that prevents blood from clotting properly.
An inherited disease that affects mostly males and prevents normal blood clotting. It is treated by lifelong injections of a synthetic version of the clotting factor lacking in persons with the disease.
several hereditary blood-coagulation disorders in which the blood fails to clot normally because of a deficiency or an abnormality of one of the clotting factors; a recessive trait associated with the X-chromosome so manifested almost exclusively in males
A hereditary bleeding disorder, in which blood does not clot normally. People with the disorder bleed for longer periods of time, which is of greatest concern when bleeding occurs internally: in the joints, tissues, muscles, and especially the vital organs, such as the brain. Many hemophiliacs rely on regular transfusions of the clotting factor in plasma.
A human sex-linked recessive genetic disorder that results in the absence of certain blood-clotting factors, usually Factor VII. Hemophiliacs suffer from an inability to clot their blood.
An inherited disease in which the body lacks blood coagulation (clotting) factors.
a disorder that prevents normal blood clotting. Hemophilia is hereditary.
an inherited disorder in which a person's blood lacks a certain protein important in forming blood clots, leading to excessive bleeding
A disease that makes it difficult for the blood to clot, which is how the blood sticks together to stop flowing. Without clots, a simple cut can cause someone to lose a dangerous amount of blood. This disease affects mostly boys.
Any of several hereditary blood coagulation disorders occurring almost exclusively in males. Because blood does not clot properly, even minor injuries can cause significant blood loss that may require a blood transfusion, with its associated minor risk of infection.
A hereditary blood defect that occurs almost exclusively in males and is characterized by delayed clotting of the blood. This leads to difficulty in controlling bleeding, even after minor injuries. Ryan White was a hemophiliac.
A genetic blood disorder, almost always in males, in which blood does not clot properly as a result of an enzyme deficiency.
A sex-linked inherited bleeding disorder that generally only affects males. The disorder is characterized by a tendency to bleed spontaneously or at the slightest injury because of the lack of certain clotting factors in the blood.
a hereditary disorder in which the blood does not clot normally, so that cuts or sores bleed for longer than normal.
a condition in which a person’s blood does not clot
a condition in which an individual lacks the factors in blood which helps blood to clot (to prevent bleeding) in the event of an injury. Hemophilia is a monogenic disorder and an X-linked recessive disorder.
A blood disorder characterized by prolonged bleeding, and the inability of the blood to clot properly.
Hemophilia is a bleeding disorder caused by a deficiency in one of the blood clotting factors. (Read about " Bleeding Disorders")
Hemophilia (hem-o-FEEL-e-a) is an inherited disease in which a particular clotting factor is missing. This means that when people with hemophilia receive an injury that breaks the skin, it takes longer for their body to stop the bleeding and start healing.

A sex-linked inherited blood disease found almost exclusively in men. It is characterized by delayed blood clotting and difficulty in controlling hemorrhage, even after minor injury.
Group of hereditary disorders in which affected individuals fail to make enough of certain proteins needed to form blood clots.
genetic blood disorder in which blood does not clot properly. It almost always occurs in males, though women can be carriers.
a blood-clotting disorder.
(He-mo-fil-i-ah) (Greek haimat-blood, philos-fond) This inherited disorder of blood is manifested by an increased tendency to bleed. It causes a defect in the body's mechanism to control bleeding, even if it is due to trivial injury. There are two types hemophilia, namely A and B. Some of the manifestations are: Bleeding that doesn't stop within a few minutes of infliction, Hemearthrosis or bleeding into a joint cavity producing painful hot swollen joints and muscle hematomas in the calf. .
A congenital condition due to the inadequate synthesis of one of the clotting factors.
a genetic disorder that affects mostly men and prevents normal blood clotting. It is treated by life-long injections of a synthetic version of the clotting factor lacking in people with the disease. (The new recombinant clotting factor replaces the natural product, which was extracted from people's blood and, when not heat-treated, could carry HIV.)
