Prolonged bleeding

Prolonged bleeding means blood that takes much longer than usual to stop — after a cut, a dental extraction, an injury, surgery, or childbirth — or that restarts after seeming to stop. Stopping bleeding depends on two things working together: platelets (which form the first plug at the site of injury) and clotting factors (which build a firm mesh to seal it). A problem with either can cause prolonged bleeding. Low or poorly working platelets — from a low platelet count, or from medicines such as aspirin — tend to cause immediate, prolonged oozing from small cuts and mucous surfaces. Clotting-factor problems — inherited (hemophilia, von Willebrand disease) or acquired (liver disease, which makes the factors; vitamin K deficiency; or blood-thinning drugs like warfarin) — can cause bleeding that is delayed or into deeper tissues such as joints and muscles. The context is the clue: a lifelong pattern of bleeding easily, or a strong family history, points toward an inherited disorder; a new tendency in an adult raises the possibility of a medication, a liver problem, or a low platelet count. A single episode of slower-than-expected bleeding is often nothing, but a consistent pattern deserves assessment.

• Blood-thinning medication — warfarin, direct oral anticoagulants, or antiplatelet drugs like aspirin.
• Low platelet count (thrombocytopenia).
• Von Willebrand disease — the commonest inherited bleeding disorder.
• Hemophilia — inherited clotting-factor deficiency, especially in boys and men.
• Liver disease — the liver makes clotting factors.
• Vitamin K deficiency.
• Disseminated intravascular coagulation (DIC) — in someone seriously ill.

For prolonged bleeding without an obvious cause, or with other bleeding signs, blood tests help sort out the mechanism: a full blood count including the platelet count, and clotting tests — the prothrombin time (PT/INR) and aPTT. The pattern across these is informative: a low platelet count points one way; a prolonged aPTT with a normal PT suggests a factor problem such as hemophilia or von Willebrand disease; both times prolonged suggests liver disease, vitamin K deficiency or DIC; and a raised INR is expected on warfarin. Specific von Willebrand factor and clotting-factor assays are arranged by a haematologist when an inherited disorder is suspected. Mediora.AI can surface a low platelet count or an abnormal clotting time from your results that fits a bleeding tendency; interpreting the pattern belongs with your doctor or haematologist.
