Has anybody had to take their loved one with dementia for a colonoscopy? The actual colonoscopy itself is not my worry, I am rather selfishly wondering how the prep is to be managed. I can't get MIL to drink 75ml of liquid so how am I going to get her to drink 5000ml in the morning and 5000ml in the afternoon? (OR vice versa depending on the time of the appointment.) As for not eating for 24 hours plus. It's going to be 24 hours plus of raging and crying and running round to the neighbours, and calling the police, and saying we're abusing her. And the house will have to be cleared of food otherwise I'll doze off sometime during it and she'll be feeding her face. Her bedroom is upstairs and the loo is downstairs so she probably won't be able togo to bed and sleep, and if by some miracle she can, what if she falls down the stairs because of hunger or dehydration or trying to get to the downstairs loo? She's 84 and confabulates a lot. She's already decided that she will take some of the "medicine" in between meals and that the doctor said that was ok. She has no idea how much liquid we're talking about. She finds a 100ml glass to be outrageously huge, and drinking even half of that to be an unreasonable request. During the many months of treatment for constipation we've failed to get her to drink more than 150ml mls a day that isn't tea. At the hospital for several hours today my husband and I both peed multiple times, but MIL not at all. What the hell am I going to do?
