Q

How does diet affect bowel elimination?
* Gas producing foods
* Food intolerance
*Fluid intake
* Spicy foods
* High fiber foods

A

Gas-producing foods-cause the intestinal walls to become distended, increasing the colon motility. Such foods are onions, cauliflower, and beans
Food intolerance- digestive upset, and in some instances, cause watery stools, cramps, or flatulence.
Fluid intake or loss- Increased water intake eases the passage of feces, while poor fluid intake increases the risk of constipation
Spicy foods- Diarrhea and flatus
Constipating-producing foods
High fiber foods- foods improves the likelihood of a normal elimination pattern such as whole grains, fresh fruits and vegetables

Q

How does emotional stress affect bowel elimination?
How does depression affect bowel elimination?

A

Emotional stress accelerates the digestive process, and peristalsis is increased resulting in diarrhea, nausea and gastric distention.
Depression may slow peristalsis resulting in constipation.

33
Constipation
Due to increased water absorption in the colon, constipation leads to difficulty passing stool, excessive straining at defecation, the inability to defecate at will, hard feces, and rectal pain.
34
Straining during defecation can
induce elevations in intraocular pressure, increased intracranial pressure, changes in cardiac rhythms, and hemorrhoids.
35
Valsalva maneuver consists of
“bearing down” while holding the breath. The person thus is exerting force against a closed windpipe, creating increased intrathoracic pressure.
36
Impaction
The presence of hard fecal mass in the rectum or colon which the patient is unable to expel Symptoms are loss of appetite, nausea, vomiting, distention, cramping, and rectal pain. Other causes are Barium used in radiologic examinations contributes to the risk of impaction. Diagnosis of impaction is through digital examination and palpation of fecal mass.
