Wakes up and makes bowel movement states she's done. Washes up. She makes another one while drying hands. Clueless. Back on the pot. This happens 3-4 times and ends up 1-2 hrs on the pot. This is only when she gets up in the late morning. Dr states unsure what it is take her to the ER. really? this has happened for 2 days. NO fever, no constipation, have not changed her food. Is it her demensia or what?
Are you sure she is not constipated or "blocked" a bit?
You can still have a BM but retain stool that will become more and more difficult to evacuate.
With dementia some of the "cues" we normally use to tell our brain that we are done are diminished so she may feel that she still has to go.
If you can redirect after the first BM and get her dressed and into the kitchen for a bit of breakfast that might help get her mind of trying to go again. After a bite to eat she can try again if she wishes but I think if you keep her occupied she might wait a bit longer.
An increase of fiber and fluids might help if she is a bit constipated.
My mother had dementia for about 6 years; she also had a lot of OCD issues pertaining to BMs and the toilet in general. I often said, if it wasn't for having to use it, she'd have hardly any issues at ALL! :( She was either falling off the toilet onto the floor, having to use it constantly or not at all due to constipation or diarrhea, having blow outs that required huge clean up efforts, asking for laxatives to help her & then having issues stemming from that, and on and ON. I think mom spent more time on the bowl than she did in her bed!
You can rarely rely on a doctor to give you straightforward answers when it comes to dementia related behaviors b/c they don't understand them EITHER! The human brain is something we're still in the Dark Ages about, truthfully. You are the one who is best equipped to figure out your loved one by using trial and error methods. Try this, if it doesn't work, try that. Which may sound stupid, but it's your best bet since there are no foolproof answers when it comes to 'how to treat dementia'. Put a pull up brief on the woman after she has a BM so that if another is coming right away, the brief will catch it. It's worth a try.
Good luck!
