Taking Care of Your Bowels--The Basics

Contents

What is the bowel, and what does it do?

The bowel is the last portion of your digestive tract and is sometimes called the large intestine or colon. The digestive tract as a whole is a hollow tube that extends from the mouth to the anus. 

The function of the digestive system is to take food into the body and to get rid of waste. The bowel is where the waste products of eating are stored until they are emptied from the body in the form of a bowel movement (stool, feces). 

A bowel movement happens when the rectum (last portion of the bowel) becomes full of stool and the muscle around the anus (anal sphincter) opens.

[The intestines] With a spinal cord injury, damage can occur to the nerves that allow a person to control bowel movements. If the spinal cord injury is above the T-12 level, the ability to feel when the rectum is full may be lost. The anal sphincter muscle remains tight, however, and bowel movements will occur on a reflex basis. This means that when the rectum is full, the defecation reflex will occur, emptying the bowel. This type of bowel problem is called an upper motor neuron or reflex bowel. It can be managed by causing the defecation reflex to occur at a socially appropriate time and place. 
A spinal cord injury below the T-12 level may damage the defecation reflex and relax the anal sphincter muscle. This is known as a lower motor neuron or flaccid bowel. Management of this type of bowel problem may require more frequent attempts to empty the bowel and bearing down or manual removal of stool.

Both types of neurogenic bowel can be managed successfully to prevent unplanned bowel movements and other bowel problems such as constipation, diarrhea and impaction.

Methods for emptying the bowel

Each person's bowel program should be individualized to fit his/her own needs. The type of disease or nerve damage (for example, upper or lower motor neuron) should be taken into account as well as other factors (see What Factors can Affect the Success of the Bowel Program, below). Components of a bowel program can include any combination of the following:

What is a bowel program?

Most people perform their bowel program at a time of day that fits in with their prior bowel habits and current lifestyle. The program usually begins with insertion of either a suppository or a mini-enema, followed by a waiting period of approximately 15-20 minutes to allow the stimulant to work. This part of the program should, preferably, be done on the commode or toilet seat.

After the waiting period, digital stimulation is done every 10-15 minutes until the rectum is empty. In order to avoid damage to the delicate rectal tissue, no more than four digital stimulations should be performed in any one session. Those with a flaccid bowel frequently omit the suppository or mini-enema and start their bowel programs with digital stimulation or manual removal. Most bowel programs require 30-60 minutes to complete.

Bowel programs vary from person to person according to their individual preferences and needs. Some people use only half of a suppository, some require two suppositories, and some use no suppository or mini-enema at all. Some choose to do the entire program in bed, while others sit on the toilet from the beginning. Some find that the program works better if they can eat or drink a warm beverage while it is in progress, others find that this is not helpful. What is most important is that you discover what works best for you.

Factors that can affect success

Any one of the factors listed below, or a combination of factors, can affect the success of a bowel program. Changing one factor may produce results almost immediately, or it may take several days to see the results. Changing more than one factor at a time makes it difficult to determine the effects of individual factors, and may increase the time it takes to develop a stable bowel program.
