Constipation
• Abnormal infrequency or irregularity of defecation; any
variation from normal habits may be a problem.
• Causes include medications, chronic laxative use,
weakness, immobility, fatigue, inability to increase intraabdominal pressure, diet, ignoring urge to defecate, and
lack of regular exercise.
• Increased risk in older age.
• Perceived constipation: a subjective problem in which the
person’s elimination pattern is not consistent with what
he or she believes is normal.

• Decreased appetite
• Headache
• Fatigue
• Indigestion
• A sensation of incomplete evacuation
• Straining at stool
• Elimination of small-volume, hard, dry stools

Patient Learning Needs
• See Chart 38-1

Interventions to prevent and relieve
constipation
•
Adequate fluid intake.
•
High-fiber diet.
•
Establish regular pattern of defecation
•
Respond immediately to the urge to defecate.
•
Minimize stress. – Sympathetic response.
•
Promote adequate activity and exercise.

Assume sitting or squatting position.
•
Administer laxatives as ordered
•
TYPES:
•
Chemical irritants- provide chemical stimulation to
intestinal wall- increase peristalsis . Ex. Dulcolax, castor oil,
senokot (senna)
•
Stool lubricants – mineral oil
•
Stool softeners – Colace (Na Docussate)
•
Bulk formers – Metamucil
•
Osmotic agents – Milk of magnesia, duphalac

TEACHING ABOUT MEDICATIONS
Cathartics and Laxatives
 Cathartics are drugs that induce defecation. They can
have strong, purgative effect. A laxative is mild in
comparison to a cathartic, and it produces soft or liquid
stools that are sometimes accompanied by abdominal
cramps.
 Cathartics: Castor oil, cascara, phenolphthalein and
bisacodyl.
 Laxatives are contraindicated in the client who has
nausea, cramps. Colic, vomiting, or undiagnosed
abdominal pain. Clients need to be informed about the
dangers of laxative use.

Question
What is an example of a laxative osmotic agent?
A. Bisacodyl (Dulcolax)
B. Dioctyl sodium sulfosuccinate (Colace)
C. Magnesium hydroxide (Milk of Magnesia)
D. Polyethylene glycol and electrolytes (Colyte)
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Answer
D
Polyethylene glycol and electrolytes (Colyte) are an
osmotic agent. Bisacodyl (Dulcolax) is a stimulant
laxative. Dioctyl sodium sulfosuccinate (Colace) is a fecal
softener. Magnesium hydroxide (Milk of Magnesia) is a
saline agent.

Diarrhea
• Increased frequency of bowel movements (more than 3
per day), increase amount of stool (more than 200 g per
day), and altered consistency (i.e., looseness) of stool.
• Usually associated with urgency, perianal discomfort,
incontinence, or a combination of these factors.
• May be acute or chronic.
• Causes include infections, medications, tube feeding
formulas, metabolic and endocrine disorders, and various
disease processes.
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Manifestations

• Milk are temporary withheld
• Avoid raw fruits and vegetables, fried foods, spices coffee.
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Nursing Care
• Directed toward identifying
the cause, relieving
symptoms, preventing
complications and if
infectious, preventing the
spread of infection to others.

What is IBS?
• Also known as spastic colon, spastic colitis, mucous
colitis and irritable colon
• Most common functional disorder of the GIT
• Causes increased motility of the small or large intestine
• Affects the intestine’s structure, but cause is unknown
• Does not lead to or cause ulcerative colitis or cancer
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Signs and Symptoms
 Causes alternately tense and flaccid bowel segments
 Symptoms vary in intensity and pattern
 Aggravated by foods, alcohol ingestion, stress and fatigue
 Resulting symptoms include:
 Nausea
 Abdominal pain
 Cramps
 Flatulence (gas)
 Altered bowel function (constipation or diarrhea)
 Hypersecretion of colonic mucus
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Diagnosis
 Upper GI series
 Barium enema
 Colonoscopy appropriate for
older adults
 Tests that eliminate other
pathologies with similar
symptoms
 Nursing Alert!
 Rectal Bleeding and fever
are not associated
symptoms of IBS. The
person with these
symptoms should report to
a physician for evaluation.
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Treatment
 Lifestyle changes
 Counseling
 Biofeedback and relaxation training
 High-fiber diet and agents that add
bulk like Metamucil and Effersyllium
 Adequate oral fluids and regular
meal patterns
 Limitation of dairy products if lactose
intolerant
 Medications for symptomatic relief
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Types of Medications

 Help quiet the bowel’s activity
 Provide relaxation
 Antispasmodic agents like dicylclomine hydrochloride (Bentyl)
and hyoscyamine (Donnatal)
 Relieve pain and cramping symptoms
 Common side effects:
Dry mouth

dizziness
 Antidiarrheal agents like loperamide (Imodium) to maintain
normal activity

Intestinal Obstructions
• Mechanical obstruction
• Functional obstruction
• Small bowel
• Large bowel
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Intestinal Obstruction
• Blockage of intestinal tract that inhibits
passage of fluid, gas, feces
• Caused by
– mechanical obstruction (strangulated
hernia, adhesion, cancer, volvulus,
intussusception)
– neurogenic obstruction (paralytic ileus,
uremia, electrolyte imbalance(low K),
spinal cord lesion)
– Vascular disease (occlusion of superior
mesentery vessels)
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Intestinal Obstructions
• Paralytic Ileus or “silent bowel” is most often seen after
abdominal surgery & anesthesia
• bowel activity is < due to lack of neural stimuli
(“functional”)
• this can lead to “mechanical” obstruction due to
accumulation of feces
• Hernias: a loop of bowel protrudes through abdominal
wall
• inguinal canal, umbilicus, or incisional scar tissue
• caused by heavy lifting, straining, or coughing
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Sigmoid Volvulus
• Sigmoid Volvulus (twisting): usually seen in the
older individual with a history of straining at stool
– Symptoms: abdominal distention, nausea,
vomiting, and crampy abdominal pain; check
history of flatus and BMs
– Abrupt onset is indicative of an acute
obstruction
– Sudden onset due to “torsion or hernia?”
• A chronic history of constipation is related to a dx
of diverticulitis or carcinoma
• Obstipation (no flatus or BM) & loss of weight =
carcinoma
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Sigmoid Volvulus
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Intussusception
• only 5-15 % occurrence in adults
• s/s colicky abd pain, nausea, vomit, diarrhea,
constipation
• diagnosed by barium enema, CT scan
• treated via surgical resection

•
Crohn's disease causing adhesions or inflammatory strictures
•
Neoplasms benign or malignant
•
