Rather than focusing on a single one-size-fit-all approach to restoring bowel regularity, Regular aims to help readers identify the likely cause of their irregular bowel patterns and offers a wide variety of personalized solutions.  For example, Freuman explains that while a high fiber diet that might help someone with slow transit constipation, it could make symptoms worse for someone constipated as the result of pelvic floor muscle dysfunction. Regular will guide readers to narrow down the specific cause of their irregularity and provide tips, including—questions to take to your next doctors visit; tables listing foods likely to be problematic and suggested alternatives; sample menus for different therapeutic diets; and foods and supplements that may be helpful for specific types of diarrhea and constipation.
