D69.9

Clinical Causes: Blood clotting disorders (e.g., hemophilia, thrombocytopenia) Trauma or injury causing internal or external bleeding Use of anticoagulant medications Blood vessel abnormalities or damage Infections that affect blood clotting mechanisms Liver disease affecting production of clotting factors Certain cancers that invade blood vessels or affect blood clotting Vitamin deficiency (e.g., vitamin K deficiency)

Key Symptoms: Unexplained or sudden bleeding from gums or nose Easy bruising or formation of large, painful bruises Blood in urine or stool Persistent bleeding from cuts or wounds Heavy or abnormal menstrual bleeding Signs of internal bleeding such as abdominal pain, dizziness, or fainting Blood spots under the skin (petechiae) Increased fatigue or weakness in case of significant blood loss

Diagnosis Path: Complete blood count (CBC) to evaluate red blood cells, platelets, and hemoglobin levels Coagulation studies such as prothrombin time (PT), activated partial thromboplastin time (aPTT), and fibrinogen levels Blood clotting factor assays Blood type and crossmatch, especially if transfusion is needed Imaging studies like ultrasound or CT scans if internal bleeding is suspected Tests to identify underlying causes like liver function tests or infectious disease screening

Treatment Protocols: Stabilizing blood pressure and volume with IV fluids and transfusions Controlling bleeding through local measures such as pressure or surgical intervention if necessary Medications like vitamin K, clotting factor concentrates, or antifibrinolytics Adjusting or discontinuing blood-thinning medications under medical supervision Treating underlying conditions, such as infections or liver disease Monitoring and supportive care to prevent complications
