Recently my Mother had a bout with constipation, and for about 4 days did not have feces. After having her drink lots of water & prune juice, and then 1/2 a dose of ex-lax one day & 1/2 a dose the next day, she finally was flushed of everything in her little system. Here we are almost a week later going through another 4 days without feces, except she seems fine otherwise. On the prior episode, she was complaining of pain when she tried to go but couldn't. I treated her for hemorrhoids on the first episode. She walking, eating, drinking, and seems normal, but no regularity as far as I have been able to tell. She has moderate to severe dementia.
