The surgery that fixes the injury is its own injury. The body does not know the difference between a scalpel and a knife.
The stress response
Cut into a person, even to help them, and the body reacts the way it reacts to any wound. It floods with stress hormones, cortisol and catecholamines, burns through its reserves, and releases a wave of inflammatory signals meant to defend and repair. This is the surgical stress response, and it is not a side effect. It is the operation, seen from the inside.
The brain gets the message
Those inflammatory signals, chief among them a cytokine called IL-6, do not stay at the incision. They travel, loosen the blood-brain barrier, and wake the brain's resident immune cells, the microglia. The result is neuroinflammation, and for some patients, postoperative cognitive dysfunction: the fog, the word-finding lapses, the not-feeling-like-yourself that can follow an operation and linger.
Who pays the most
The older the patient and the more surgeries required, the heavier the load. Each operation to repair a serious injury stacks another round of inflammation on a brain that has less reserve to absorb it. A wreck that takes three surgeries to rebuild a body has asked that body to survive three controlled traumas.
The lesson
When a client is not the same after the operations that were supposed to make them whole, the change is not weakness or exaggeration. It is a documented consequence of what surgery does to the body and the brain. Claim only what the literature supports, keep it honest, and it supports the point: the cure has a cost, and the cost is real.
