8. Case Study Name: Dawn Tootin Age: 42 Sex: Female Medical History: Non-smoker, No prior history of major illnesses No known drug allergies Presenting Complaint: Patient reports frequent heartburn, especially after eating, and occasional regurgitation of food and spicy food.

10. What do you think is going on with Dawn? Irritable bowel syndrome (IBS) Allergic to spicy food Gastroesophageal reflux disease (GERD) Peptic Ulcer Disease

11. Pathophysiology Lower Esophageal Sphincter Dysfunction Hiatal Hernia Gastric Motility disorders Delayed gastric emptying Gastroparesis Gastroesophageal reflux disease (GERD)

12. What medications would be effective? Lifestyle Changes could we recommend? Education: What education could we provide our patient? What types of food should she avoid?

13. Medication Prescribed: Omeprazole 20 mg daily: A proton pump inhibitor (PPI) that reduces stomach acid production, thereby minimizing esophageal irritation. Lifestyle Advice: Avoid trigger foods (e.g., spicy foods, caffeine, and chocolate). Eat smaller, more frequent meals. Avoid lying down immediately after eating and elevate the head of the bed.
