35. CCA Study Notes: Normal Bowel Movements and Stool Observations

The Big Picture

A bowel movement removes waste from the body. Before this happens, partly digested food and fluids move from the stomach through the intestines. Fluid is absorbed, and the remaining waste becomes more solid.

People do not all have bowel movements at the same time or with the same frequency. Knowing a client’s usual bowel routine helps you follow that routine whenever possible. Careful stool observations are important for the care-planning process.

Course Notes: Key Ideas You Need to Know

How Waste Becomes Stool

Food and fluids that have been partly digested in the stomach are called chyme.

Chyme moves from the stomach into the small intestine and then into the large intestine. The large intestine is also called the large bowel or colon.

The colon absorbs fluid from the chyme. As this happens, the material becomes more solid.

Once the semi-solid waste reaches the colon, it is called feces.

How Feces Move Through the Intestine

Feces move through the intestine by peristalsis. This process involves alternating contraction and relaxation of the intestinal muscles.

The feces move through the colon to the rectum. The rectum stores them until they leave the body.

Defecation is the process of passing feces from the rectum through the anus . It is also called a bowel movement or BM.

Stool means feces after they have been excreted from the body.

Normal Bowel Movement Frequency

There is no single bowel movement schedule that applies to everyone.

On average, people may have a bowel movement:

  • every day
  • every 2 to 3 days
  • two or three times in one day

People also have bowel movements at different times. One person might usually go after breakfast, while another might usually go in the evening.

Some older people expect a bowel movement every day and become concerned when their routine changes. Reassurance from members of the care team can help reduce this anxiety.

Normal Stool Colour

Normal stool is brown. Bile produced by the liver gives stool its normal brown colour and plays an important part in digestion.

Stool colour can change for several reasons.

  • Some iron-replacement medications can make stool look black or tarry.
  • Bleeding in the stomach, small intestine, or both can also cause black or tarry stool.

Tarry stool is black, unformed, and sticky, similar to tar.

  • Bleeding in the lower colon or rectum can make stool appear red.
  • Eating beets can also make stool appear red.
  • Eating a large amount of green vegetables can produce green stool.
  • Various diseases and infections can produce clay-coloured, white, pale brown, orange, or green stool.

Melena means dark, tarry stools containing decomposing blood.

Normal Stool Consistency, Shape, and Odour

Normal stools are usually:

  • soft
  • formed
  • moist
  • shaped like the rectum

Stool has a characteristic odour because of bacterial action in the intestines. Normal flora bacteria are necessary for stool to form.

Certain foods, including eggs, onions, and garlic, can affect stool odour. Some medications, including some multivitamins, can also make stool smell foul.

The Bristol Stool Form Scale

The Bristol Stool Form Scale describes seven stool types.

TypeStool Form
Type 1Separate hard lumps that are difficult to pass
Type 2Sausage-shaped but lumpy
Type 3Sausage-shaped with cracks on the surface
Type 4Smooth, soft, and shaped like a sausage or snake
Type 5Soft blobs with clear edges that pass easily
Type 6Fluffy, mushy pieces with ragged edges
Type 7Watery and completely liquid, with no solid pieces

Know the Client’s Regular Bowel Routine

Whether you work in the community or in a facility, know the client’s usual bowel routine.

Follow that routine whenever possible.

For example, if the client prefers to use the commode chair for a bowel movement, help the client use it.

Record Bowel Movements Accurately

CCA action: Whether you work in the community or in a facility, accurately record the client’s bowel movements during your shift.

These records give the care team information they use when deciding whether changes to diet or medications are needed.

The support worker records and observes. The care team decides whether adjustments are necessary.

What to Observe in Stool

Careful stool observations contribute to the care-planning process .

Observe:

  • colour
  • amount
  • consistency
  • odour
  • shape
  • size

What to Do When You Notice Abnormal Stool

If you work in a facility and observe abnormal stool, ask a nurse to observe the bowel movement.

Also report:

  • abnormalities in bowel movement frequency
  • client complaints of pain
