Gastrointestinal Disorders & Diseases

Question 1

Which condition is characterized by chronic inflammation of the gastrointestinal tract, often affecting the small intestine and colon?

Accepted Answer

Crohn's disease

Answer

Crohn's disease is a type of inflammatory bowel disease (IBD) characterized by chronic inflammation that can affect any part of the gastrointestinal tract, from the mouth to the anus. It often involves patches of inflammation that penetrate deep into the bowel wall, commonly affecting the small intestine and colon. Symptoms include abdominal pain, diarrhea, and weight loss.

Question 2

Which bacterial infection is a common cause of peptic ulcers?

Accepted Answer

Helicobacter pylori

Answer

Helicobacter pylori (H. pylori) is a spiral-shaped bacterium that can infect the stomach lining. It is a major cause of peptic ulcers, which are open sores that develop on the inside lining of the stomach and the upper part of the small intestine. The bacteria weaken the protective mucus layer, making the stomach lining more susceptible to damage from stomach acid.

Question 3

What is the most common symptom of gastroesophageal reflux disease (GERD)?

Accepted Answer

Heartburn

Answer

Heartburn is the most common symptom of gastroesophageal reflux disease (GERD), characterized by a burning sensation in the chest, often behind the breastbone. It occurs when stomach acid frequently flows back into the esophagus, irritating its lining. This reflux is typically due to a weakened or relaxed lower esophageal sphincter.

Question 4

Which condition results from an autoimmune reaction to gluten, causing damage to the small intestine?

Accepted Answer

Celiac disease

Answer

Celiac disease is an autoimmune disorder where the ingestion of gluten, a protein found in wheat, barley, and rye, leads to damage in the small intestine. This damage impairs the absorption of nutrients, causing various digestive and systemic symptoms. It requires a strict, lifelong gluten-free diet for management.

Question 5

Which condition is characterized by small pouches forming in the walls of the colon that can become inflamed or infected?

Accepted Answer

Diverticulitis

Answer

Diverticulitis is a condition where small, bulging pouches, called diverticula, form in the walls of the colon. When these pouches become inflamed or infected, it leads to diverticulitis, causing symptoms like abdominal pain, fever, and changes in bowel habits. It is often associated with a low-fiber diet.
