Which of the following is a common postoperative complication?

Hemorrhage is a common postoperative complication because it can occur immediately after surgery or may develop days later. Postoperative hemorrhage arises from various sources, including surgical site complications, vascular injuries, or issues with clotting. It is critical for healthcare providers to monitor patients closely for any signs of excessive bleeding, such as changes in vital signs, drainage from surgical sites, or significant pain, as timely intervention is essential to manage this complication effectively and prevent further morbidity.

While insomnia, headaches, and constipation can occur after surgery due to medications, stress, or changes in activity levels, they tend to be less immediately life-threatening and more commonly regarded as discomforts rather than severe complications. Hemorrhage, on the other hand, potential leads to hypovolemic shock and other serious health risks, highlighting its significance as a key concern in postoperative care.
