Not quite, but I understand you have only twitter to glean information from and I appreciate you attempting to update people.

Basically what happened is unrelated to his medication, but is exacerbated by something that he takes to thin his blood, which he's done since he had a stroke a few years ago. He has polyps in his colon, a hernia, bleeding ulcers, and something to do with his esophagus too -- basically his digestive system seems to be in bad shape all round! -- but he does not have cancer, which was the big worry (especially with him being a higher than usual risk for colon cancer).

I have no idea how serious the problems he actually has are; you know my mom, she's light on details, and they're quite likely to be garbled. I don't know what's going to be done about them, how long he'll be in hospital, how he's feeling, if he's still in intensive care or not, or anything really. (I did e-mail her and tell her I'm here so she'll know to call my mobile or e-mail me rather than try to phone home, don't worry).
