My grandmother died 3 months ago and a month before that, her urine color is purple. she was wearing a urine tube. i was wondering why is that?

Sorry to hear: I'm sorry to hear of the loss of your grandmother. Such goodbyes are hard. About the urine, this is a question for her doctor. I hope he/she is accessible and can answer this more specifically for you. In the meantime, when there's blood in the urine, it can have a purplish color. Certain meds can change the urine's color too. I hope you can reach her doctor and gain some insight.

Seen in elderly: Women more then men with catheters, three or 4 different bacteria could have been involved- no treatment unless symptomatic- called purple bag syndrome.
