## Inflammatory Bowel Disease (IBD) ### Overview - **Definition:** IBD is a group of chronic inflammatory conditions affecting the gastrointestinal tract, characterized by episodes of remission and exacerbation. - **Types of IBD:** - **Crohn's Disease:** Can affect any part of the GI tract from mouth to anus, commonly involves skip lesions and deep, transmural inflammation. - **Ulcerative Colitis:** Affects only the colon and rectum with continuous mucosal inflammation. ### Crohn's Disease - **Location:** Most frequently affects the ileum and ascending colon but can occur anywhere in the GI tract. - **Pathophysiology:** Transmural thickening that leads to "skip lesions" and a characteristic "cobblestone" appearance due to deep, penetrating granulomas. - **Symptoms:** - Abdominal pain (often right lower quadrant), diarrhea (less likely to be bloody), weight loss, fatigue, and malnutrition. - Possible complications include strictures, fistulas, and abscesses. - **Complications:** - Fistulas (abnormal connections between bowel segments or other organs). - Strictures (narrowing of bowel segments). - Abscess formation and increased risk for malnutrition. - **Nursing Assessment:** - **Health History:** Duration and pattern of symptoms, including abdominal pain, frequency, and consistency of stools. Family history of IBD or autoimmune disorders, weight loss, dietary habits, and medication use. - **Physical Exam:** Assess for abdominal tenderness, especially in the right lower quadrant. Check for signs of malnutrition (e.g., muscle wasting, pallor). Inspect for fistulas or signs of abscesses, especially around the perianal area. - **Management:** - **Medications:** - Aminosalicylates (e.g., sulfasalazine) to decrease inflammation. - Corticosteroids for acute flares to control severe inflammation. - Immunomodulators (e.g., azathioprine) and biologic therapies (e.g., infliximab) for patients with severe disease. - **Nutritional Support:** High-protein, high-calorie, low-residue diet to reduce bowel stimulation. Vitamin and mineral supplementation as needed due to malabsorption. - **Surgery:** Reserved for complications like obstruction or fistulas; surgery can relieve symptoms but is not curative. ### Ulcerative Colitis - **Location:** Involves the colon and rectum in a continuous pattern, starting in the rectum and extending upward. - **Pathophysiology:** Affects the mucosal and submucosal layers, causing widespread ulceration and inflammation. - **Symptoms:** - Left lower quadrant pain, frequent and urgent bloody diarrhea, abdominal cramping, tenesmus (feeling of incomplete evacuation), and fatigue. Systemic symptoms may include fever, anemia, and weight loss during severe flares. - **Complications:** - Toxic megacolon (acute dilatation and thinning of the colon, risking perforation). - Severe bleeding due to ulcerations. - Increased risk for colorectal cancer over time. - **Nursing Assessment:** - **Health History:** Duration, frequency, and consistency of diarrhea, presence of blood in stool, family history of IBD. Diet, stress levels, history of past episodes, and medication compliance. - **Physical Exam:** Abdominal tenderness, especially in the left lower quadrant. Signs of dehydration (e.g., dry mucous membranes, poor skin turgor) due to frequent diarrhea. Check stool for blood and consistency; assess skin around the perianal area for irritation from frequent stool passage. - **Management:** - **Medications:** - 5-Aminosalicylates (e.g., mesalamine) as first-line treatment. - Corticosteroids for acute flares. - Immunomodulators and biologics for more severe disease or frequent flare-ups. - **Dietary Recommendations:** Low-residue, high-protein, high-calorie diet. Avoid foods that may exacerbate symptoms, such as high-fiber and spicy foods. - **Surgery:** Total colectomy (surgical removal of the colon) may be curative. ### Common Complications of IBD - **Electrolyte Imbalance:** Due to frequent diarrhea, leading to dehydration and hypokalemia. - **GI Bleeding:** Especially common in ulcerative colitis due to mucosal ulcerations. - **Toxic Megacolon:** Severe dilation of the colon that can lead to perforation; requires emergency treatment. - **Perforation:** Particularly in severe cases of ulcerative colitis. - **Malabsorption and Malnutrition:** Due to reduced absorption in Crohn's disease. ### Diagnostic Studies - **Laboratory Tests:** CBC (check for anemia), electrolytes (detect imbalances), inflammatory markers (ESR, CRP), liver function tests, and albumin levels. - **Stool Studies:** Culture and sensitivity, ova and parasites, fecal occult blood test to rule out infection and bleeding. - **Imaging:** Abdominal X-ray, CT scan, MRI for structural and inflammatory changes. - **Endoscopy:** Colonoscopy, proctoscopy to visualize inflammation and obtain biopsy samples. ### Collaborative Goals and Interventions - **Goals:** - Control inflammation and symptoms. - Maintain nutritional balance. - Reduce frequency and urgency of bowel movements. - Prevent complications and support emotional well-being. - **Medications:** - Antidiarrheals: To reduce bowel movement frequency. - Antispasmodics: For cramping and pain management. - Corticosteroids: To reduce inflammation during flare-ups. - Biologics: For patients unresponsive to conventional therapy. - **Nutritional Support:** Low-residue, high-calorie, high-protein diet to support energy needs. Avoid foods that exacerbate symptoms (e.g., high-fat, dairy if intolerant). ### Nursing Process for IBD - **Assessment:** - **Onset and Duration:** Frequency, urgency, and characteristics of diarrhea, pain, nausea, weight loss. - **Physical Exam:** Abdominal tenderness, stool inspection for consistency and blood, signs of malnutrition and dehydration. Skin: Assess perianal area for breakdown due to frequent stools. - **Nursing Diagnoses:** Diarrhea, Acute pain, Deficient fluid volume, Imbalanced nutrition, Activity intolerance, Risk for impaired skin integrity. - **Planning and Goals:** Restore normal bowel patterns, manage pain, prevent dehydration, maintain nutrition, reduce risk of complications, provide education. - **Interventions:** - **Manage Diarrhea:** Identify triggers, provide easy access to bathrooms, record stool frequency and characteristics. - **Skin Integrity:** Protect perianal skin with barrier creams, frequent hygiene after bowel movements. - **Nutritional Support:** May require total parenteral nutrition (TPN) if malnutrition is severe. - **Patient Education:** - Understanding Disease: Chronic nature of IBD, triggers, and management techniques. - Diet: Low-residue, high-protein, high-calorie diet to minimize irritation. - Medication Adherence: Importance of compliance with prescribed medications. - Ileostomy Care: For patients requiring surgery, stoma care, and dietary adjustments. ### Practice Questions with Answers **1.
