Acute inflammation of the gallbladder, typically caused by obstruction of the cystic duct by gallstones or biliary sludge. Without prompt treatment, complications include gangrene or perforation.

Rapid onset inflammatory process of the pancreas causing local and systemic manifestations. Ranges from mild edematous to severe necrotizing pancreatitis with multi-organ failure.

Mucosal defects extending through the muscularis mucosae of the stomach or duodenum. Most commonly caused by H. pylori infection or NSAID use.

Functional gastrointestinal disorder characterized by chronic/recurrent abdominal pain with altered bowel habits in the absence of structural or biochemical abnormalities. Involves gut-brain axis dysregulation.

Mechanical obstruction of the small intestine preventing normal passage of intestinal contents. Most commonly caused by adhesions from prior surgery, hernias, or tumors.

Chronic dyspeptic symptoms (epigastric pain, early satiety, postprandial fullness) without identifiable structural cause on investigation. A disorder of gut-brain interaction.

Delayed gastric emptying in the absence of mechanical obstruction. Most commonly idiopathic or diabetic in etiology. Causes nausea, vomiting, early satiety, and bloating.

Life-threatening rupture of an abdominal aortic aneurysm causing massive internal hemorrhage. Mortality exceeds 80% without emergency surgical repair. Classic triad: abdominal/back pain, hypotension, pulsatile mass.

Sudden reduction in intestinal blood flow causing bowel ischemia and potentially infarction. Most commonly due to arterial embolism (50%), arterial thrombosis (25%), or non-occlusive mesenteric ischemia (20%). Mortality 60-80% if diagnosis delayed.

Symptom complex of epigastric pain/burning, postprandial fullness, or early satiation. Requires systematic approach to distinguish organic causes (PUD, malignancy) from functional dyspepsia.

Gram-negative bacterial infection of the gastric mucosa affecting approximately 50% of the world's population. Major cause of peptic ulcer disease and gastric cancer. Eradication cures most H. pylori-associated ulcers.

Systematic approach to evaluating acute abdominal pain in adults. Requires rapid assessment to identify life-threatening conditions requiring urgent intervention while systematically working through the differential diagnosis.
