This condition is called hemophilia.
Hemostasis occurs in a sequence: 1. Vasoconstriction 2. Formation of platelet plug 3. Formaion of clot Bleeding time is the time from the onset of bleeding till the stoppage of bleeding i.e. temporary hemoststic plug formation (platelet plug). Clotting time is the time from the onset of bleeding till the clot formation (i.e. definitive hemostatic plug). Hence, clotting time is longer then bleeding time.
Hemophilia is a bleeding disorder that slows down the blood clotting process. People who have hemophilia often have longer bleeding after an injury or surgery. People who have severe hemophilia have spontaneous bleeding into the joints and muscles. Hemophilia occurs more commonly in males than in females.The two most common types of hemophilia are hemophilia A (also known as classic hemophilia) and hemophilia B (also known as Christmas disease). People who have hemophilia A have low levels of a blood clotting factor called factor eight (FVIII). People who have hemophilia B have low levels of factor nine (FIX).The two types of hemophilia are caused by permanent gene changes (mutations) in different genes.
If this clotting occurs in the larger arteries, it results in major tissue damage.
A Common Disease Were Bleeding Occurs Is Hemophilia. Hemophilia Means... (hē'mə-fĭl'ē-ə, -fēl'yə) Any of several hereditary blood-coagulation disorders in which the blood fails to clot normally because of a deficiency or abnormality of one of the clotting factors. Hemophilia, a recessive trait associated with the X-chromosome, is manifested almost exclusively in males.
Disseminated Intravascular Coagulation
The most important part of clotting is the platelets. These cells are designed specifically to activate when bleeding occurs. However, special proteins are required to allow the platelets to do their job. ,
Here are some causes of bleeding disorder:1. ThrombocytopaeniaThere is a deficient number of circulating platelets. Petechiae appears due to spotaneous, widespread haemorrhage. It can be treated with transfusion of concentrated platelets.2. Impaired liver functionThe liver does not have the ability to synthesise procoagulants. This eads to vitamin K deficiency, hepatitis, and cirrhosis.3. HaemophiliaIt includes several similar hereditary bleeding disorers. Haemophilia A is the most common type of haemophilia and it occurs due to factor VIII deficiency. Haemophilia B is due to factor IX deficiency. As for haemophilia C, this condition is mild and occurs to the the deficiency of factor XI.
any of several X-linked genetic disorders, symptomatic chiefly in males, in which excessive bleeding occurs owing to the absence or abnormality of a clotting factor in the blood.
Iron Anaemia occurs due to the deficiency of ironas well as folic acid.
Platelets are a component of blood which are involved in blood clotting which stops bleeding and stops infection. However, if clotting occurs during the normal circulation of the blood, the clot might lodge in some blood vessel, cutting of the blood supply to vital organs, such as the heart.
Platelets (thrombocytes) are the smallest type of blood cell. They are important in blood clotting. When bleeding occurs, the platelets swell, clump together, and form a sticky plug that helps stop the bleeding. If there are too few platelets, uncontrolled bleeding may be a problem. If there are too many platelets, there is a chance of a blood clot forming in a blood vessel. Also, platelets may be involved in hardening of the arteries (atherosclerosis).
