GI and GU Chronic Condition Case Studies: GERD, IBS, BPH
This paper presents three case studies involving chronic gastrointestinal and genitourinary conditions. The first case examines a 46-year-old male diagnosed with gastroesophageal reflux disease (GERD), covering differential diagnoses, upper endoscopy workup, proton pump inhibitor therapy, and lifestyle modifications. The second case analyzes a 27-year-old female diagnosed with irritable bowel syndrome (IBS), applying Rome criteria and addressing stress- and diet-related triggers alongside pharmacological options. The third case evaluates a 65-year-old male with benign prostatic hyperplasia (BPH), detailing combination drug therapy with finasteride and tamsulosin and relevant patient education strategies. Each scenario integrates clinical reasoning, diagnostic testing rationale, and both pharmacological and nonpharmacological treatment approaches.
- Scenario 1: Gastroesophageal Reflux Disease (GERD): GERD diagnosis based on presenting symptoms and differentials
- Diagnostic Testing and Differential Diagnosis for GERD: Upper endoscopy, x-ray, and manometry workup
- Treatment and Lifestyle Modifications for GERD: PPIs, Baclofen, surgery, and diet changes
- Scenario 2: Irritable Bowel Syndrome (IBS): IBS diagnosis using Rome criteria and trigger identification
- Scenario 3: Benign Prostatic Hyperplasia (BPH): BPH diagnosis, combination drug therapy, patient education
- Conclusion: Summary of clinical reasoning across all three cases

What makes this paper effective
- Each case follows a consistent clinical reasoning structure — primary diagnosis, differential diagnoses, diagnostic workup, and treatment — making the paper easy to follow and professionally organized.
- The paper integrates both pharmacological and nonpharmacological interventions for each condition, demonstrating a holistic approach to patient management.
- Evidence-based support from authoritative sources (NIDDK, National Cancer Institute, peer-reviewed journals) lends credibility to each diagnostic and treatment recommendation.
Key academic technique demonstrated
The paper demonstrates applied clinical reasoning by anchoring each diagnosis to specific patient-reported symptoms and then systematically ruling out alternative conditions. For IBS, the use of the Rome criteria as a named diagnostic framework shows familiarity with specialty-specific evidence-based standards, elevating the analysis beyond simple symptom matching.
Structure breakdown
The paper is divided into three parallel scenario sections, each progressing from diagnosis to workup to treatment. This parallel structure is effective for a case study format: it allows readers to compare clinical approaches across conditions while keeping each scenario self-contained. The inclusion of patient-specific details (age, lifestyle factors, comorbidities) ties the clinical recommendations directly to the individual, which is characteristic of well-executed case-based writing at the undergraduate health sciences level.
Scenario 1: Gastroesophageal Reflux Disease (GERD)
The primary diagnosis in this scenario is gastroesophageal reflux disease (GERD). This diagnosis is based on the strength of the presenting symptoms. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK, 2014), symptoms associated with GERD include "regular heartburn, a painful, burning feeling in the middle of your chest, behind your breastbone, and in the middle of your abdomen." The 46-year-old male in this case presents those very same symptoms. In essence, the patient's symptoms result from the backflow of stomach contents into his esophagus. Given that this has been occurring over the past couple of months, the lining of his esophagus is irritated, hence the need for immediate medical attention to ease symptoms.
The differential diagnosis in this scenario is peptic ulcer disease — specifically gastric ulcers, which are open sores on the stomach's inner lining. A person suffering from gastric ulcers is likely to experience discomfort in the middle of the abdomen described as a burning sensation. The differential diagnosis could also include gastroparesis, dyspepsia, and gastritis.
Diagnostic Testing and Differential Diagnosis for GERD
To confirm the primary diagnosis, additional diagnostic testing is warranted. An upper endoscopy would be useful for examining the 46-year-old's esophagus and stomach. In the case of GERD, this procedure would most likely reveal esophagitis. Upper endoscopy also permits biopsy, in which case the collected tissue could be assessed further — for example, for Barrett's esophagus. Other diagnostic procedures to consider include an upper digestive system X-ray and esophageal manometry.
