Diverticulosis and Diverticulitis :

 Diverticulosis and Diverticulitis :

It is crucial to understand the difference between these two conditions. A simple analogy is to think of a weak spot on a tire.


Definition

  • Diverticulosis:
    A condition characterized by the formation of small pouch-like protrusions (diverticula) in the wall of the colon, especially in the sigmoid colon. These pouches form due to weakness in the intestinal wall and increased intraluminal pressure.

  • Diverticulitis:
    When one or more of these diverticula become inflamed or infected, leading to pain, fever, and other systemic symptoms.

Diverticulosis

Pathophysiology of Diverticulosis: 

Diverticula form when increased pressure within the colon pushes the inner lining through weak spots in the muscular wall. A low-fiber diet is believed to contribute to this by leading to harder stools and increased straining during bowel movements, which raises intracolonic pressure.

Risk Factors of Diverticulosis:

    • Age (incidence increases with age, particularly over 60)
    • Low-fiber diet
    • Obesity
    • Lack of exercise
    • Smoking
    • Certain medications (e.g., NSAIDs, steroids)
    • Symptoms: Most individuals with diverticulosis are asymptomatic. When symptoms do occur, they can include mild abdominal cramping, bloating, and constipation or diarrhea.
Diagnosis of Diverticulosis: 

Often discovered incidentally during a colonoscopy, sigmoidoscopy, or other imaging studies like a CT scan or barium enema.

Treatment of Diverticulosis: 

Primarily dietary and lifestyle modifications. A high-fiber diet, adequate fluid intake, and regular exercise are recommended to prevent progression to diverticulitis.

Diverticulitis

Pathophysiology of Diverticulitis: 
Occurs when one or more diverticula become inflamed or infected. This can happen when stool or undigested food particles get trapped in the pouch, leading to bacterial overgrowth and inflammation. Complications can include abscess formation, perforation (a hole in the colon wall), fistula formation (an abnormal connection between two organs), and peritonitis.

Symptoms of Diverticulitis:
    • Sudden onset of persistent abdominal pain, often in the lower left quadrant (the most common site for diverticula).
    • Fever and chills.
    • Nausea and vomiting.
    • Change in bowel habits (constipation or diarrhea).
    • Abdominal tenderness.
Diagnosis of Diverticulitis: 

Typically diagnosed based on symptoms and physical examination. A CT scan of the abdomen and pelvis is the most accurate diagnostic test, revealing inflamed diverticula, abscesses, or other complications. Blood tests may show an elevated white blood cell count.

Treatment of Diverticulitis: 

Depends on the severity of the condition.
    • Uncomplicated Diverticulitis: May be managed at home with antibiotics, pain relievers, and a clear liquid diet that gradually progresses to a low-fiber diet.
    • Complicated Diverticulitis (e.g., with abscess, perforation, obstruction): Requires hospitalization. Treatment may include IV antibiotics, IV fluids, bowel rest (NPO), and possibly percutaneous drainage of an abscess or surgical intervention (e.g., colectomy to remove the affected portion of the colon).

Medical Management

For Diverticulosis:

  • High-fiber diet (whole grains, fruits, vegetables)

  • Adequate fluid intake

  • Avoidance of constipation (bulk-forming laxatives if needed)

  • Regular exercise

For Diverticulitis (Acute phase):

  1. Bowel Rest: NPO → clear liquid diet → low-fiber → high-fiber gradually

  2. Antibiotics: Broad-spectrum (e.g., Metronidazole, Ciprofloxacin)

  3. IV Fluids: Maintain hydration and electrolyte balance

  4. Pain management: Analgesics (Avoid NSAIDs)

  5. Surgery (if complications occur):

    • Abscess drainage

    • Bowel resection (if perforation, peritonitis, or fistula)

Goals / Expected Outcomes

Nursing Interventions

Rationale

Evaluation

1. Acute Pain related to inflammation

Patient will verbalize pain relief within 24 hours.

- Assess pain location, intensity, and duration.
- Administer prescribed analgesics.
- Encourage rest and relaxation techniques.
- Apply warm compress to abdomen if allowed.

To monitor progress, relieve pain, and promote comfort.

Patient reports decreased pain; vital signs stabilize.

2. Deficient Fluid Volume related to fever and NPO status

Patient will maintain adequate hydration (moist mucous membranes, normal BP, urine output ≥ 30 mL/hr).

- Monitor vital signs, skin turgor, and I&O.
- Provide IV fluids as ordered.
- Encourage oral fluids when allowed.

Maintains fluid and electrolyte balance.

Patient remains hydrated and hemodynamically stable.

3. Imbalanced Nutrition: less than body requirements

Patient will maintain adequate nutrition once oral intake resumes.

- Keep patient NPO during acute phase.
- Gradually introduce clear liquids, then low-fiber diet.
- Consult dietitian for meal planning.

Prevents bowel irritation and promotes healing.

Patient tolerates diet and maintains weight.

4. Knowledge Deficit regarding disease and diet

Patient will verbalize understanding of dietary and lifestyle modifications.

- Educate about high-fiber diet after recovery.
- Instruct to avoid nuts, seeds (controversial), and constipation.
- Encourage fluid intake and exercise.

Promotes self-care and prevents recurrence.

Patient correctly states dietary measures.

5. Risk for Infection related to perforation or abscess

Patient will remain free from signs of systemic infection.

- Monitor temperature and WBC count.
- Observe for abdominal distension and rigidity.
- Administer antibiotics as prescribed.
- Maintain aseptic technique.

Early detection and prevention of infection complications.

Patient remains afebrile; WBC normalizes.

Health Teaching

  • Follow high-fiber diet once inflammation resolves.
  • Avoid straining during bowel movements.
  • Maintain adequate hydration (2–3 L/day).
  • Avoid NSAIDs and other irritants.
  • Regular colorectal check-ups.
  • Report symptoms like severe abdominal pain, fever, or blood in stool immediately.

Expected Outcomes

  • Relief from abdominal pain and tenderness.
  • Restoration of normal bowel habits.
  • Normal WBC and temperature.
  • Improved knowledge of preventive measures.
  • No complications such as abscess or perforation.
