I would reccommend a diet much higher in fluids, mostly water. Have her drink 6-8 8oz glasses A DAY, EVERY DAY. Dehyrdation is the biggest cause of severe constipation. OTC fiber supplements can also help move things along, many older people have this same problem and good hydration and supplemental fiber usually work. Things to look for internally- possibly a blockage somewhere in the small intestine or along the digestive tract. A colonoscophy (spelling??) might be a good idea as well, to check for pollups or any other problems. Hope this helps. BTW, I am only an EMT, but I have read a good deal of medical info/books. And I did stay at a Holiday Inn Express last night.

Good luck to you and her man.
