Hey Auberon, when you said:-

"I have trouble walking to the loo, sitting on the loo, getting off the loo, & washing my hands, let alone the rest of it like replacing clothing."

I am with you on this one, I often just sit because getting up is just too hard.
I've have also fallen asleep on the throne and woken up numb from the waist down!

Funny thing is that I used to laugh at my elderly patients who were bowel fixated------now that is me
Cheers Tayla

I too get constipation, my family think that the medications cause it. Its horrible - I can be sat on the loo for hours
Treatment -

Get more fiber or bulk in your diet.


Regular physical activity is an important component in bowel health. That will be hard.


Drink plenty of fluids, especially water and fruit juices. Drink 6-8 glasses of water daily in addition to your beverages with meals.


Go to the toilet at the same time every day—preferably after meals—and take enough time.


Use nondigestible sugar (lactulose) or specially formulated solutions.


Avoid using over-the-counter laxatives. Try to avoid laxatives containing senna (Senokot) or buckthorn (Rhamnus purshiana) because long-term intake may damage the lining of your bowel and injure nerve endings to the colon.


Try a daily exercise such as the knee-to-chest position. Such positions may activate bowel movements. Spend about 10-15 minutes in this position. Breathe in and out deeply.
