Culprit #3: Candy, cookies, cake -- oh my!

The Consequence: Constipation. Not getting the recommended 25 to 35 grams of daily fiber means you don't have enough to absorb fluid and add bulk for easier BMs.

The Cure: Gradually increase the amount of fiber in your diet with lots of fruits and veggies, and be sure to drink plenty of water. Having trouble eating enough? Ask your doc about fiber pills. And for relief in a hurry, a stool softener or laxative such as Colace or Milk of Magnesia may help.
