Though many cases of bowel obstruction cannot be prevented, a patient may be able to reduce risk factors for some forms of bowel obstruction by practicing the following:

• Eating a diet high in fiber (whole-grain cereals and breads, beans, fresh fruits and vegetables). Fiber helps bulk up and soften stool, stimulating intestinal contractions that help move food through the digestive system. Gradually adding fiber to a diet can help to avoid problems with gas or bloating.
  
  It is important to drink increased amounts of fluids while increasing fiber intake. These increases should be gradual. Suddenly eating large amounts of fiber when the body is not used to it may cause constipation.
  
  
• Avoiding excessive fats and sugar. Maintaining a balanced diet by avoiding excessive fats and sugar can help promote normal bowel function.
  
  
• Drinking plenty of fluids. Water and other fluids add bulk to stool, making bowel movements softer and easier to pass. The recommended daily amount of fluid is eight 8-ounce glasses. Caffeine (e.g., coffee, soda) and alcohol should be avoided since they have a dehydrating effect on the body.
  
  
• Exercising regularly. Exercise helps to stimulate intestinal activity, speeding the passage of food through the digestive system. Swimming, walking or engaging in other forms of exercise for at least 30 minutes on most days of the week can help promote normal bowel movements.
  
  
• Not ignoring the urge to defecate. Recognizing and responding to the body’s signals to defecate can help prevent constipation. Bowel movements that are purposefully withheld or delayed may lead to hard, dry stool that is painful to pass or becomes obstructed.
