Organ failure refers to a condition where one or more organs in the body are no longer able to perform their normal functions. This can be due to various reasons such as disease, injury, poisoning, or infection. Organ failure can lead to serious health complications and may even be life-threatening if not treated promptly. The severity of organ failure depends on the extent of damage caused to the affected organs. In some cases, organ failure can be reversible while in others it may be permanent. Treatment for organ failure typically involves addressing the underlying cause and providing supportive care to help the body recover.
