Gastroesophageal Reflux and Peptic Ulcer Disease

Gastroesophageal reflux disease (GERD) and peptic ulcer disease are the principal acid-peptic disorders of the upper digestive tract. In GERD, gastric contents move back into the oesophagus and cause symptoms such as heartburn and regurgitation or mucosal injury; in peptic ulcer disease, defects in the lining of the stomach or duodenum develop largely because of Helicobacter pylori infection or non-steroidal anti-inflammatory drug use. Both are common reasons for adults to seek care and are central topics in medical-surgical nursing.

Definition

Gastroesophageal reflux disease is a condition in which reflux of stomach contents causes troublesome symptoms or complications, while peptic ulcer disease is the presence of mucosal breaks in the stomach or duodenum that reach the submucosa, both grouped as acid-peptic disorders.

Scope

The entry covers the definitions, mechanisms, presentation, and management context of GERD and peptic ulcer disease as a reference subject for nursing. It addresses the role of acid, H. pylori, and NSAIDs, the recognition of complications such as bleeding, and the multidisciplinary management framework, without giving individualised drug dosing or treatment instructions.

Core questions

• How do reflux and mucosal ulceration arise from imbalance between acid-peptic aggression and mucosal defence?
• How do GERD and peptic ulcer disease present, and how are alarm features recognised?
• What roles do Helicobacter pylori and NSAIDs play in peptic ulcer disease?
• How are complications such as upper gastrointestinal bleeding identified and monitored?

Key concepts

• Acid-peptic aggression and mucosal defence
• Lower oesophageal sphincter and reflux
• Erosive versus non-erosive reflux disease
• Helicobacter pylori infection
• NSAID-related ulceration
• Upper gastrointestinal bleeding
• Alarm symptoms (dysphagia, weight loss, anaemia)

Mechanisms

GERD results when the antireflux barrier at the gastro-oesophageal junction, principally the lower oesophageal sphincter, fails to prevent retrograde movement of acidic gastric contents, leading to symptoms or mucosal injury; transient sphincter relaxations, hiatal hernia, and impaired oesophageal clearance contribute (Katz et al., 2013). Peptic ulcer disease arises when the balance between aggressive factors (gastric acid and pepsin) and mucosal protective factors is disrupted, most often by Helicobacter pylori infection, which provokes inflammation and impairs defence, or by non-steroidal anti-inflammatory drugs, which reduce protective prostaglandins; eradication of H. pylori changes the natural history of the disease (Malfertheiner et al., 2017).

Clinical relevance

GERD and peptic ulcer disease are encountered across primary, medical, and surgical settings, and their complications—including erosive oesophagitis, strictures, and gastrointestinal bleeding—can be serious. Recognising typical and alarm presentations supports timely escalation; this entry describes the disorders for reference and is not a basis for individual diagnostic or treatment decisions.

Epidemiology

GERD is among the most prevalent gastrointestinal conditions, with a systematic review estimating population prevalence in the order of 10-20% in Western countries and somewhat lower in Asia (El-Serag et al., 2014). Peptic ulcer disease is closely tied to the prevalence of Helicobacter pylori infection and to NSAID use, and its incidence has declined in many regions as H. pylori prevalence has fallen and eradication has become routine (Malfertheiner et al., 2017).

Frequently asked questions

What is the difference between GERD and peptic ulcer disease?

GERD is the backflow of stomach contents into the oesophagus causing symptoms or mucosal injury, whereas peptic ulcer disease is the formation of ulcers in the lining of the stomach or duodenum; both are acid-peptic disorders but affect different parts of the upper digestive tract.

What are the main causes of peptic ulcers?

The two predominant causes are Helicobacter pylori infection and the use of non-steroidal anti-inflammatory drugs, which together account for the large majority of peptic ulcers.
