Coagulation Disorders
Bleeding after small cuts is more common in platelet disorders than in coagulation disorders
What our notes say
- Bleeding after small cuts is more common in platelet disorders than in coagulation disorders (Internal Medicine End of Semester CAT (MBChB 4): haematology and renal, 30 MCQs )
- A coagulation disorder is any abnormality of the haemostatic system that results in either excessive bleeding (hypocoagulability) or pathological clot formation (hypercoagulability). (Coagulation disorders)
- Haematology — interpretation of FBC and blood film; approach to anaemia; iron deficiency; megaloblastic anaemia; haemolysis; sickle cell disease; thalassaemia; leukaemias and lymphomas; myeloma; platelet disorders; coagulation disorders; transfusion reactions. (Year 4 Internal Medicine: Exam Revision Roadmap)
- Other contributing causes: coagulation disorders, neoplasms, vasculitis, aneurysms, vascular malformations (Cerebrovascular Disease: Stroke, Ischemia & Hemorrhage Explained)
- Prophylaxis: keep >5–10 x10^9/L (higher if sepsis, drug use, coagulation disorders) ( Transfusion: Governance, Donor Selection & Blood Groups)
- DIC probably causes bleeding more commonly than all congenital coagulation disorders combined. (Hematologic Malignancies and Bleeding Disorders)

Practice questions on Coagulation Disorders
Most common cause of acquired coagulation disorder?
- Vitamin K deficiency
- Liver disease
- DIC
- Medication-induced
Answer: B. The liver synthesizes nearly all coagulation factors — liver disease is the most common acquired coagulopathy globally.
