Medical complications refer to unexpected problems that can arise during or after medical treatment, affecting a patient's recovery. These complications can occur due to various factors, such as the patient's overall health, the type of procedure performed, or even the medications used. For example, a patient undergoing surgery may experience infections or bleeding, which can delay healing and require additional treatment. Preventing medical complications is crucial for ensuring patient safety and successful outcomes. Healthcare providers often take precautions, such as monitoring vital signs and providing proper post-operative care, to minimize risks. Patients can also play a role by following their doctor's instructions and reporting any unusual symptoms promptly, helping to catch complications early.
