There are posts regarding Schiavo being alone in the room with Terri. Afterwards, Terri appeared to be in insulin shock.

Going back to the beginning, part of Terri's condition is related to a potassium imbalance. Can a person be poisoned by potassium, say in their food or drink?

I'm not a medical expert by any means, but I think a potassium imbalance can be caused by any number of things, from gastro-intestinal disorders to bulimia (which purportedly could be one of Terri's problems). Possibly on food or drink, but I think that might be a more unlikely scenario than having a stomach virus or something like that. Maybe someone in Terri's family could tell us more about her codition way back when, if that's what you're getting at.

I am glad someone else brought that up. I went and looked it up and I found out it can cause irregular heartbeat and even cardiac arrest if you take more than the recommended daily allowance.
