This assignment presents a series of healthcare case studies focusing on various gastrointestinal disorders. The cases cover conditions such as peptic ulcer disease (PUD), gastroesophageal reflux disease (GERD), upper GI bleeding, diverticulitis, portal hypertension, ascites, hepatic encephalopathy, sudden onset abdominal pain, acute cholecystitis, and pancreatitis. Each scenario includes a patient presentation, relevant medical history, and questions regarding the causes, mechanisms, and contributing factors related to each condition. The assignment explores the factors that contribute to the development of these disorders, the mechanisms behind their formation, and the clinical manifestations observed in each case. The cases also delve into the diagnostic processes and the rationale behind the healthcare provider's diagnoses. The student's analysis provides insights into the complex interplay of factors leading to these gastrointestinal issues.
