Final answer:
Crohn's disease is an inflammatory bowel disease that can affect any part of the GI tract but most commonly affects the ileum of the small intestine, leading to various gastrointestinal symptoms and potential complications.
Step-by-step explanation:
Crohn's disease (CD) is an inflammatory bowel disease with the potential to affect any part of the gastrointestinal (GI) tract, though it most commonly impacts the ileum, or the final part of the small intestine. Symptoms such as abdominal pain, diarrhea, fever, and weight loss are typical of this condition. Owing to faulty absorption, malnutrition can be a significant issue for those with the disease.
Additionally, Crohn's disease sufferers may experience complications such as bowel obstructions and an elevated risk of bowel cancer. A key aspect of managing Crohn's disease is aimed at symptom palliation, as there is no known cure, with treatments such as anti-inflammatory drugs and lifestyle adjustments helping to control the disease and improve life quality.
