IBS Case Study: SOAP Note Assessment and Treatment
This case study presents a clinical encounter with a 45-year-old Caucasian female experiencing persistent abdominal pain, bloating, and alternating bowel habits over two weeks. Using the SOAP (Subjective, Objective, Assessment, Plan) note framework, the paper documents the patient's history, physical examination findings, and diagnostic reasoning. The primary diagnosis of Irritable Bowel Syndrome (IBS) is established through Rome IV criteria after excluding differential diagnoses including gastrointestinal infection, ovarian cyst, and small intestinal bacterial overgrowth (SIBO). The treatment plan integrates pharmacologic intervention (dicyclomine), dietary modification targeting high-FODMAP foods, lifestyle changes, and structured follow-up, reflecting a holistic, patient-centered approach to chronic functional gastrointestinal disease.

What makes this paper effective
- The paper follows a clear, structured clinical format (SOAP) that mirrors real-world practice, making complex diagnostic reasoning easy to follow.
- Differential diagnoses are addressed systematically, with reasoning provided for why each alternative was deprioritized — demonstrating rigorous exclusionary logic.
- The treatment plan is genuinely holistic, balancing pharmacologic, dietary, lifestyle, and follow-up components, each supported by brief evidence-based rationale.
Key academic technique demonstrated
The paper demonstrates diagnosis by exclusion anchored in formal criteria — specifically the Rome IV criteria for IBS. Rather than simply naming a diagnosis, the writer methodically rules out competing conditions by linking the absence of specific findings (fever, blood in stool, gynecological symptoms) to the elimination of each differential, showing how clinical reasoning works in practice.
Structure breakdown
The paper opens with a brief theoretical framing of the SOAP method, then moves through patient demographics and history (HPI, medications, social/family history, ROS), physical exam findings, primary diagnosis with supporting evidence, three differential diagnoses with ICD-10 codes, a multi-part treatment plan, and closes with a personal reflective paragraph. This mirrors the standard clinical case study genre expected at the graduate nursing or advanced practice level.
Introduction
In clinical practice, the patient assessment and management process stands as the cornerstone of healthcare provision. This case study presents a detailed exploration of a patient encounter from a recent practicum site visit. Drawing upon the essential components of the SOAP (Subjective, Objective, Assessment, Plan) note template, the paper examines the patient's subjective experiences, objective manifestations, differential diagnoses, treatment strategy, and reflective insights. The overarching aim is to illustrate the integration of clinical reasoning, evidence-based practices, and thoughtful reflection in patient-centered care. Through this case study, a deeper understanding of the interplay between medical science and compassionate care is sought, fostering appreciation for the multifaceted nature of healthcare provision.
Patient History and Subjective Findings
Patient Information: Age: 45 | Sex: Female | Race: Caucasian
Chief Complaint (CC): Persistent abdominal pain and bloating.
History of Present Illness (HPI): The patient is a 45-year-old Caucasian female presenting with a chief complaint of persistent abdominal pain and bloating that has been distressing her for the past two weeks. The pain is primarily localized in the lower abdomen and occasionally radiates to her lower back. The discomfort is characterized as a dull ache accompanied by noticeable gassiness. She describes her bowel habits as alternating between periods of constipation and diarrhea. She denies any recent dietary changes or modifications in her medication regimen. The pain tends to worsen following meals. She rates the severity of her pain as 6 out of 10 on the pain scale and has not sought prior medical attention for these symptoms.
Current Medications: None reported.
Allergies: No known medication, food, or environmental allergies.
Past Medical History (PMHx): Immunization status up to date. No significant past medical illnesses or surgeries.
Social History (Soc Hx): The patient works as an office manager and engages in recreational activities such as gardening and hiking. She is a non-smoker and occasionally consumes alcohol. She consistently uses her seatbelt while driving and maintains functional smoke detectors at her residence. She resides with her spouse and two adult children. She adheres to safe driving practices regarding cell phone use. Her support system is robust, rooted in strong familial ties, and she actively participates in social activities within her community.
Family History (Fam Hx): Family history of hypertension on the maternal side. Deceased father due to a heart attack.
Review of Systems (ROS):
General: No weight loss, fever, chills, weakness, or fatigue.
Gastrointestinal: No anorexia, nausea, vomiting, or diarrhea. No blood in stool or abdominal pain reported outside of the chief complaint.
Genitourinary: No burning on urination. Last menstrual period: 28 days ago.
Neurological: No headache, dizziness, syncope, paralysis, ataxia, numbness, or tingling. No change in bowel or bladder control.
Psychiatric: No history of depression or anxiety.
Physical Examination and Objective Findings
Upon physical assessment, the patient appeared anxious and uncomfortable. Her vital signs were within normal limits. Abdominal examination revealed mild distention with tenderness upon palpation in the lower quadrants. Bowel sounds were present and normal in frequency. No palpable masses or organomegaly were noted. Pertinent positive findings included abdominal tenderness and bloating, while relevant negative findings included the absence of fever and rebound tenderness.
Assessment and Differential Diagnoses
The primary diagnosis of Irritable Bowel Syndrome (IBS) encapsulates a condition that remains enigmatic and prevalent within gastroenterology. The patient's persistent abdominal pain, bloating, and alternating bowel habits form a clinical picture that corresponds closely with the established profile of IBS (El-Salhy et al., 2019). The hallmark of this diagnosis is its characteristic symptomatology — a constellation of gastrointestinal distress including abdominal discomfort, bloating, and alternation between constipation and diarrhea — all of which mirror the patient's presentation.
A central facet of the IBS diagnosis is its status as a diagnosis of exclusion. The comprehensive review of the patient's medical history, combined with careful analysis of her presenting symptoms, systematically eliminates alarming features that might indicate an alternative or more severe underlying pathology. Application of the Rome IV criteria — the cornerstone of IBS diagnosis — confirms alignment of her symptoms with this functional disorder. The absence of fever, significant weight loss, blood in the stool, and other red flags serves as crucial confirmatory checkpoints. Moreover, the chronicity of her symptoms over a two-week period is consistent with the chronic nature of IBS (El-Salhy et al., 2019). The primary diagnosis of IBS thus emerges as a comprehensive encapsulation of the patient's clinical narrative, substantiated by meticulous clinical reasoning and evidence-based criteria.
Gastrointestinal Infection (ICD-10: A09): Given the recent onset of symptoms, consideration of a gastrointestinal infection is warranted. However, the absence of fever, vomiting, and recent travel history makes this diagnosis less likely (Natarajan et al., 2022).
Ovarian Cyst (ICD-10: N83.20): Although less likely, an ovarian cyst could contribute to abdominal discomfort and bloating. This diagnosis is of lower priority due to the absence of significant gynecological symptoms.
Small Intestinal Bacterial Overgrowth — SIBO (ICD-10: K90.89): SIBO is a condition characterized by an abnormal increase in bacteria within the small intestine, leading to gastrointestinal symptoms (Rao & Bhagatwala, 2019). Symptoms can include abdominal pain, bloating, and changes in bowel habits similar to those described by the patient. SIBO can arise from altered gut motility, structural abnormalities, or underlying conditions that affect gut health.
