What Is Irritable Bowel Syndrome (IBS)?
Irritable Bowel Syndrome (IBS) is a common functional digestive disorder characterized by abdominal pain or discomfort, bloating and changes in bowel habits (diarrhea, constipation, or both). It does not cause permanent damage to the intestines but can significantly affect daily life and well-being.
Common Causes and Risk Factors
Abnormal gut-brain signaling leading to heightened bowel sensitivity
Trigger foods and beverages (e.g., caffeine, fatty or spicy meals)
High stress, anxiety or other emotional factors
Family history of IBS or other functional bowel disorders
Hormonal fluctuations (IBS is more common in women)
Prior gastrointestinal infections or antibiotic use
Signs and Symptoms
Recurrent cramping or pain in the lower abdomen
Abdominal bloating, gas or distention
Altered bowel habits: diarrhea, constipation or mixed pattern
Mucus in the stool
Sensation of incomplete bowel evacuation
How Dr. Scott Diagnoses Irritable Bowel Syndrome (IBS)?
Dr. Scott uses a step-by-step approach:
Medical History and Symptom Evaluation
He reviews your pattern of abdominal and epigastric pain, bowel habits (diarrhea, constipation or both), diet, stress levels and family history of GI disorders.
Laboratory and Stool Tests
Blood work (CBC, metabolic panel, inflammatory markers) to rule out anemia, infection or systemic inflammation.
Stool analysis for pathogens, calprotectin or lactoferrin to exclude infections and inflammatory bowel disease.
Imaging and Endoscopic Evaluation
Abdominal ultrasound or CT scan to identify structural abnormalities or inflammation.
Upper endoscopy (EGD) to examine the esophagus, stomach and duodenum when epigastric pain is prominent.
Colonoscopy if there's persistent diarrhea, bleeding or to rule out colonic pathology.
Functional and Motility Testing
Breath tests for small intestinal bacterial overgrowth or carbohydrate malabsorption, and specialized motility studies when gut dysmotility is suspected.
