3. PPI therapy for GERD should be stopped before endoscopy is performed to confirm a diagnosis of EE.
A clinical diagnosis of GERD can be made if the presenting symptoms are heartburn and regurgitation, without chest pain or alarm symptoms such as dysphagia, weight loss, or gastrointestinal bleeding. In this setting, once-daily PPIs are generally prescribed for 8 weeks to see if symptoms resolve. If symptoms have not resolved, a twice-daily PPI regimen may be prescribed. In patients who do not respond to PPIs, or for whom GERD returns after stopping therapy, an upper endoscopy with biopsy is recommended after 2-4 weeks off therapy to rule out other causes. Endoscopy should be the first step in diagnosis for individuals experiencing chest pain without heartburn; those in whom heart disease has been ruled out; individuals experiencing dysphagia, weight loss, or gastrointestinal bleeding; or those who have multiple risk factors for BE.
4. The most serious complication of EE is BE, which can lead to esophageal cancer.
Several complications can arise from EE. The most serious of these is BE, which can lead to esophageal adenocarcinoma. BE is characterized by the conversion of normal distal squamous esophageal epithelium to columnar epithelium. It has the potential to become malignant if it exhibits intestinal-type metaplasia. In the industrialized world, adenocarcinoma currently represents more than half of all esophageal cancers. The most common symptom of esophageal cancer is dysphagia. Other signs and symptoms include weight loss, hoarseness, chronic or intractable cough, bleeding, epigastric or retrosternal pain, frequent pneumonia, and, if metastatic, bone pain.
5. Lifestyle modifications can help control the symptoms of EE.
Guidelines recommend a number of lifestyle modification strategies to help control the symptoms of EE. Smoking cessation and weight loss are two evidence-based strategies for relieving symptoms of GERD and, ultimately, lowering the risk for esophageal cancer. One large prospective Norwegian cohort study (N = 29,610) found that stopping smoking improved GERD symptoms, but only in those with normal body mass index. In a smaller Japanese study (N = 191) specifically surveying people attempting smoking cessation, individuals who successfully stopped smoking had a 44% improvement in GERD symptoms at 1 year, vs an 18% improvement in those who continued to smoke, with no statistical difference between the success and failure groups based on patient body mass index (P = .60).
Other recommended strategies for nonpharmacologic management of EE symptoms include elevation of the head when lying down in bed and avoidance of lying down after eating, cessation of alcohol consumption, avoidance of food close to bedtime, and avoidance of trigger foods that can incite or worsen symptoms of acid reflux. Such trigger foods vary among individuals, but they often include fatty foods, coffee, chocolate, carbonated beverages, spicy foods, citrus fruits, and tomatoes.
