What happens at the site of bleeding
Vessel is injured
Vasoconstriction
Platelet aggregation -> clot formation
Coagulation cascae -> clot formation
What could be deficient if a patient has platelet problems
Folate or B12
If there is a problem with platelet formation, where does the problem arise

What is a common problem effecting platelet aggregation
Function can be impaired due to medical therapies
What can cause generalised deficiencies that effect the coagulation cascade problems
Liver disease
Severe malnutrition
What are congenital and drug specific deficiencies effecting the coagulation cascade
Congenital = Haemophilia / Von willerbrands disease Drugs = Warfarin and heparin
What is haemophilia
x-linked genetic disorder effecting males
Absent/low clotting factor
What is Von willerbrands disease
Autosomal condition effecting males and females
