Question 1

What are the main risk factors for developing inflammatory bowel disease?

Accepted Answer

IBD risk factors include genetic predisposition, with family history being critical, and environmental factors such as diet high in fat and sugar, smoking, and nonsteroidal anti-inflammatory drugs. Altered immune response to gut microorganisms, dysregulation of the immune system, and prior infections also contribute. Stress and certain medications like antibiotics increase susceptibility to disease development.

Question 2

How does ulcerative colitis differ from Crohn's disease in terms of affected areas?

Accepted Answer

Ulcerative colitis affects only the mucosal and submucosal layers of the colon and rectum, with lesions appearing sequentially. In contrast, inflammatory bowel disease ii crohn s disease can impact any segment of the gastrointestinal tract from the mouth to the rectum. Ulcerative colitis typically does not cause abscesses, fistulas, obstruction, or fissures, unlike Crohn's disease.

Question 3

What pathological changes occur in the colon during ulcerative colitis?

Accepted Answer

Ulcerative colitis causes ulceration, diffuse inflammation, and epithelial desquamation of the colonic mucosa, leading to bleeding. Over time, muscular hypertrophy and fat deposition cause structural changes including bowel narrowing, shortening, and thickening. The affected mucosa shows progressive damage to superficial layers while deeper layers remain relatively spared.

Question 4

What are the primary clinical manifestations of ulcerative colitis?

Accepted Answer

Predominant manifestations include diarrhea with blood or mucus, left lower quadrant abdominal pain, and intermittent tenesmus. Systemic symptoms include anorexia, weight loss, fever, vomiting, and dehydration. Patients may experience six or more liquid stools daily. Extraintestinal manifestations such as skin lesions, eye abnormalities, and enteropathic arthritis affecting peripheral joints like the knees also occur.

Question 5

What serious complications can develop from ulcerative colitis?

Accepted Answer

Severe complications include toxic megacolon, where inflammation impairs colonic contraction causing distention, and perforation resulting from severe inflammation and ulcer formation, which can lead to peritonitis. Bleeding occurs directly from ulceration and inflammation. Additional complications include hypoalbuminemia, electrolyte imbalances, anemia, and liver abnormalities requiring careful monitoring and management.

Question 6

How do cycles of remission and exacerbation affect ulcerative colitis management?

Accepted Answer

Ulcerative colitis features cycles of remission and exacerbation, requiring ongoing monitoring and treatment adjustments. During exacerbations, symptoms intensify with increased diarrhea, abdominal pain, and systemic involvement. Understanding these disease patterns helps guide inflammatory bowel disease pharmacological management strategies and nutritional support. Patients benefit from consistent care planning that addresses both acute flares and maintenance therapy.

Question 7

What extraintestinal manifestations can accompany ulcerative colitis?

Accepted Answer

Extraintestinal manifestations include skin lesions, eye abnormalities, and enteropathic arthritis, which typically affects peripheral joints such as the knees. Liver abnormalities may also develop. These systemic complications reflect the broader inflammatory nature of IBD and require comprehensive assessment beyond gastrointestinal symptoms. Recognition of these manifestations is essential for complete patient evaluation and holistic nursing care.
