Why did I experience heavy bleeding yesterday after having surgery for internal hemorrhoids the day before yesterday?

The patient experienced severe bleeding following an internal hemorrhoid surgery the day before yesterday, which could be caused by multiple factors: 1. The bleeding might be related to the surgical procedure itself, such as an overly large or deep surgical incision injuring major arteries, or incomplete hemostasis during surgery leading to postoperative bleeding. 2. During hemorrhoid ligation, if the ligature is not tied tightly enough or if too little hemorrhoid tissue is left at the stump, the suture may slip off, causing bleeding from the wound surface. 3. Excessive straining during bowel movements or premature physical activity after surgery may tear the wound surface or rupture arteries, resulting in severe bleeding. In such situations, the patient should seek immediate medical attention for examination and treatment by a specialist. Doctors will implement appropriate hemostatic measures based on the severity of bleeding, such as manual compression, anal packing, or, if necessary, returning to the operating room for surgical ligation and hemostasis. Additionally, patients should follow proper postoperative care instructions, avoiding strenuous exercise and straining during bowel movements to reduce the risk of bleeding.
