Chapter 52: Concepts of Care for Patients With Inflammatory Intestinal Disorders

Ulcerative colitis involves continuous inflammation of the colon and rectum, manifesting through frequent bloody diarrhea, severe abdominal pain triggered by intestinal muscle contractions known as tenesmus, and potential complications including lower gastrointestinal bleeding and toxic megacolon. Crohn's disease affects any portion of the digestive tract but commonly impacts the small intestine, creating transmural inflammation that frequently results in malnutrition due to reduced nutrient absorption and formation of abnormal tissue connections called fistulas. The chapter addresses peritonitis, a life-threatening inflammation of the peritoneal membrane lining the abdominal cavity, which presents with characteristic findings such as severe pain and board-like abdominal rigidity. Pharmacological management encompasses anti-inflammatory medications, immunosuppressive monoclonal antibodies including natalizumab, and related therapies, with careful monitoring for serious adverse effects such as progressive multifocal leukoencephalopathy. Celiac disease receives attention as an immune-mediated condition requiring complete gluten elimination from the diet to prevent intestinal damage and malabsorption symptoms including fatty stools. The chapter integrates multiple nursing concepts including nutritional support, fluid and electrolyte restoration, pain management, bowel elimination regulation, and infection prevention. Dietary modifications represent a cornerstone of management, distinguishing between high-fiber approaches for diverticulosis prevention and low-fiber consumption during acute diverticulitis episodes. Nursing care emphasizes patient education regarding dietary triggers such as alcohol and caffeine, medication adherence, recognition of exacerbation signs, and strategies for maintaining quality of life despite chronic disease burden.
