Why can't i have a bowel movement daily?

Diet, fluid, other?: For some people normal bowel habit is not daily-how they are built, so to speak. For many, it can be low fiber, inadequate fluids, inactivity, low oil/fat intake (lubricates bowels). Can be med effects, low thyroid, other metabolic/hormone issues, anatomical abnormalities of gut, gyn organs, kidney issues, depression, irritable bowel, etc.. Most serious can be cancer, esp if new see your doc, .

5 things: Gut need 5 things - water, salt, oil, bulk and fiber.
