Nearly every heart transplant recipient meets insulin in the first weeks. The only question is whether you come home on it. That isn’t a prediction about outcomes—it’s pharmacology. The immunosuppression produces a glucose load no oral agent can adequately manage.
Most people have taken prednisone at some point—a five-day dose pack, a short course after a procedure. It works fast, the side effects are manageable, and then it’s done. That experience creates a frame of reference that does not apply after a transplant.
You came home from the hospital with a pill bottle. Twice daily, same times every day, and the instructions are presented as non-negotiable. Where the drug came from, what the trough number actually means, what moves it, and what the real side-effect landscape looks like.
Immunosuppression gets most of the attention, and it should. But it isn’t the only thing in the bag you bring home. A second tier of medications exists because immunosuppression opens specific doors a healthy immune system keeps closed. Each one is standing guard at a particular door.
The transplanted heart is living tissue carrying someone else’s genetic signature, and the immune system was built to treat exactly that as a threat. That isn’t a malfunction. It’s the system doing precisely what it was designed to do.
Every transplant group has the same post, usually around two in the morning: why am I always low on magnesium, and why doesn’t taking more of it fix anything? The answer runs through kidney physiology, drug pharmacology, and the particular frustration of a supplement doing a job the body keeps undoing.
Most people carry two assumptions into a transplant: that anything taken for years without incident is safe to continue, and that “natural” occupies a different category from “drug.” Both are wrong afterward, and the consequences run from destabilized medication levels to rejection.
I texted Eric that morning to say things had taken another downturn and I might not come back from this. He answered the way Eric answers: a bad joke about the Six Million Dollar Man, then something that cut straight through. I went to the OR a few hours later.
The Egyptians pulled the brain out through the nose with a hook and threw it away. It was packing material. The heart they left exactly where it was, because the heart was where the person lived. They weren’t eccentric in this, and they weren’t alone.
