My mom has this fixation she is constipated. I even write it on the calander "mom toilet" and write it on a note pad and show her and she agrees. But a few hours later says she hasn't had a bowel movement. She'll say I'm arguing with her. It happened yesterday morning again, she went and a few hours later says she hasn't. Anything else she forgets I remind her and she accepts it and brings it back to mind. But not this! She totaly blocks it out. What do I do?
Also, check that she isn't genuinely uncomfortable in the tummy. Is she getting wind or bloating, anything like that? If so, it might not hurt to ask the doctor for a quick abdominal exam.
Although, sigh, I'm afraid she'd probably forget that had been done, too...
But sympathy and creative approaches to suggesting she gives her laxatives a little more time to work, perhaps? I'd certainly give up on trying to convince her that all is well - just keep the calendar for your own peace of mind. Sorry you're having to deal with this, hugs.
A couple of months ago I told my mother that I didn't have any laxatives and she would have to handle it herself. There was anger and the next day she was telling me to go to the store -- like that was her way of handling it. She takes Miralax every day, but she wants something stronger too often.
