Can we talk INCONTINENCE?

A light plastic sheet over the mattress and under the mattress cover. Many fabric shops will have these, sold by the yard. Get one that is pliable and wont sound crinkly when your mom moves in bed, if you decide on using this.

Mattress pad(s) over the plastic sheet.

Several manufacturers make "night defense" incontinence underwear. We use the Depends brand, which seems to help. Sometimes if we notice there is a change in urination, we use these during the day. You can get coupons online for Depends brand if you decide to use them.

We have a portable "potty" in mom's room. Makes the trip to the bathroom shorter. Sometimes she uses it. Most times she feels independent and makes the trip (20 feet) to the bathroom outside her bedroom. A portable "potty" could help. The "potty" was part of a going home package after mom had been hospitalized.

There is a toilet seat attachment which raises a standard toilet seat about 10 inches. Perhaps your mom feels strained in the knees as she sits down to toilet. Getting this attachment, raising the seat, may make your mom more comfortable.

I found mom pulling her incontinence underwear up too high. Doing this the part around the legs opened and was loose. Mom has slim legs and a large stomach.
We sized down in the underwear. Better fit around the legs, snug around the stomach. We seems to have fewer leaks.

We found the longer mom has diabetes the neuropathy is worse, legs hurts lots and the stomach has grown disproportionally to what she eats. Home health twice a week comes in to show mom moving is better for her. Surprisingly mom will perform the movements while the therapist is working with her. After the therapist leaves the next day she refuses. So far have been successful only part of the time getting mom to practice the movements.

You may discuss with your mom's doctor. Test for a bladder infection, which may complicate things.
Good luck.

All the answers others have provided are great as well as loving concern. Talk with a Urologist to help because you're going to have many many infections to deal with and/or hospital stays for her. These can become very TOXIC. They can get into her blood system without her knowing. It's like dogs, they have a high tolerance to pain and by the time you know something is wrong, it could be too late.
One possibility is a cathator bag too. She could still get infections. Very important to be aware of the "signs".

Hope this helped a bit. Merry Christmas and Happy New Year

Dont forget the cranberry pills. One poster said that helped ward off the constant uti's her loved one was having. Check with doc to make sure it wont interfere with any meds she is on. Good luck.

My mom has a hospital bed and a portable commode next to her bed which is positioned behind her door. Attached to her door is a shoe rack. I have pull ups, Baby wipes, garbage bags (4 gal.) hand sanitizer, etc. Mom cannot walk but she can stand and pivot. Once she is on her commode, all items go in her can. She can put her bag in her garbage can, remove her soiled pull up, wipe herself with baby wipes, sanitize her hands with sanitizer, replacement chucks are in her wheelchair which she will let me know so I can come and remove the soiled ones, clothes, etc. I usually change her bed twice daily, chucks two at a time may be 5x daily. This is the world of incontinence. I do not complain because she is getting up to the best of her ability being almost 82 years young. I empty her commode each use. Best of Luck.

My 71 y/o 300+ pound alzheimer, parkinson, severe lymphedema, diabetes, fatty liver, disabled arm roommate for 10 years developed a 24/7 8 to 15 pull-up diaper (Depend®) a day severe urine and fecal incontinence problem 3 years ago. She could NOT change her own diaper (can't reach past her knees) which left the task to me - a prolific inventor.

From dire necessity, I invented a simple $3 one piece device (solution) and haven't had to change her pull-ups in 3 years. It is now quick and easy for her to do it herself. There is nothing else on the internet made for this purpose.

If I can find enough demand for this device, I intend to have a non-profit disabled American manufacturer mass produce and market/sell/ship them.

Because I can not post easy make-one-yourself images/videos in these incontinence websites, I'm in the process of making my own Facebook site for this purpose. I haven't chosen a FB public site name yet but sure "incontinence" will be part of the name. Keep an eye out for it.

I am a healthcare worker with lots of experience with incontinent patients. Have you ever tried using Covidian pads? They are a brand of pads made to spread out on the bed or in chairs. They hold up to a liter of fluid each. When we have heavy setters at my hospital, we spread on of these pads out under them and them with plenty of the pad right under their bottom and down their thighs. Then we pull some of the pad up between their legs to help catch some of the urine. These pads are way better than regular “chux” pads or those cloth patterned ones. I don’t know if they come in different sizes but the ones we get are fairly large and work better than anything else I’ve ever tried. I do know they’re more expensive than chux, but way more effective!
