Does anyone have any solutions for parent w/ dementia who puts foreign objects in the toilet causing backups?

1.Check her BEFORE she enters the bathroom for 'flushable' items.
2. Remove EVERYTHING from the bathroom she uses leaving only toilet paper that has no cardboard roll (you can buy it that way these days). Remove towels, packages of wipes, lotions, potions, medicine, everything in other words. So the only thing she can do in the bathroom is use the toilet. And the only thing she can flush down the toilet is her waste, the allotted toilet paper or the clothing she's wearing.
3.If she has to take a bowel movement, you'll have to accompany her into the bathroom with moistened wipes that you will figure out how to dispose of.
4. If she refuses to be accompanied into the bathroom, look into Memory Care Assisted Living for her right away. In most cases, Alzheimer's/Dementia reaches a point where the person can no longer be cared for in the home and needs a team of care givers around the clock, 24/7. Safety issues tend to also crop up, wandering at night, trying to cook in the kitchen, etc, that make the entire situation unmanageable.

I work in a Memory Care home & this morning I came in to find a very large pile of feces on the carpet in the resident hallway. Left there by a gentleman who often forgets where his toilet is and thinks it's perfectly fine to take a BM right there on the floor. Or on the upholstered chair in the living area. Again, dementia & ALzheimer's often reaches a point where in-home care is no longer feasible.

Best of luck!

Perhaps a motion detector at the entrance to the bathroom/ toilet to alert someone that she’s going in; remove any items from her person and pockets that she could flush. Only leave a small amount of toilet paper inside the bathroom. Kid proof or lock all the bathroom cabinets so she doesn’t have access to anything inside the bathroom that could be flushed. Also make sure the shower/ tub area doesn’t have any loose items ( ripe for flushing). All those items could be placed into a shower caddie ( locked up ) for use when needed.
This is a major problem for Memory Care facilities; I once spoke about this issue with the owner of my Mom’s memory care facility. Interestingly, he told me that it’s usually the male residents who pull this costly and disruptive trick.
I’m sorry you’re having to deal with this issue, but please know that you’re not alone and this is unfortunately very common with Alzheimer’s and memory- impaired people. You might call a few memory care facilities in your area and ask to speak with management about what additional measures they take for this issue.

How about putting one of those plastic urine measuring inserts in the toilet. She can load that up but when she flushes nothing in actually in the toilet bowl to flush. Good luck.

It's a bit of a p.i.t.a but disconnecting the chain in the toilet tank would make it unflushable, therefore stopping costly clogs and backups.

If your mother is putting things into the toilet and causing horrible problems as a result, she obviously is mentally incompetent. Short of keeping her locked up with a pail in a room or attaching her to you with a rope or chain, you can't stop her. You could put a lock on the bathroom door but i assure you she will find something else to destroy. This cannot be permitted no matter what but YOU have to realize without any doubts she cannot stay in your home. It is time that you put her somewhere where the facility can monitor her. I would really explode if someone did this in my home, no matter who they are or why they are doing it. I would stop it at once. This is unacceptable and you won't be able to stop her..

Ellen, what type of things is she putting in there? Depends? Clothing? Things she finds in the bathroom? Things she brings in with her? I'm rooting for the forum to come up with a do-able solution for you!

Child proof toilet lock for the lid. Hassle for you to come open it each time but ensures she won’t be unattended and flushing what she shouldn’t

I would get so mad at my mom because she would put all sorts of things in the toilet. She was so confused. It was not her fault. She has been gone for over a year now. Wish I had been more patient and understanding.

Taking care of a parent with memory loss is difficult.

She needs to be supervised when she is in the bathroom.

No fun to be the one that has to make this the new normal, but a whole lot safer than the house being destroyed by an over flowing toilet.

You can also ask the plumber to quote remodeling the bathroom into a wet room. That makes clean up easier and stops water from infiltrating the structure.

how I resolved that problem was I put a garbage plastic bag around the toliet inside. use the one that you can tighten with the strings. hang it over the outside all the way around. now the bag will be above the water and tight enough not to fall into the toilet . this way any items she put into it will not go down. it took me a few times till I got it just right. it works.
you could also tell her that the toilet is broken and she has to use the porta potty. tell her that it would be easier for her as she doesn't have to walk far . she could keep it in whatever room she is in. again put a plastic bag in it to catch anything she does. if she agrees just put a hook and eye way up on the bathroom door so she cant reach it to get it open.
good luck
