Peptic ulcer disease (PUD) is characterized by a break or ulceration in the protective mucosal lining of the lower esophagus, stomach, or duodenum. This condition stems from damage caused by hydrochloric acid buildup, leading to erosions that affect the superficial mucosa. Over time, persistent erosion can penetrate through the muscularis mucosae, damaging blood vessels and potentially causing hemorrhage or perforation of the gastrointestinal wall (McCance & Huether, 2018). The primary risk factors for PUD include genetic predisposition, infection with Helicobacter pylori (H. pylori), and the habitual use of NSAIDs and aspirin (McCance & Huether, 2018).

In contrast, gastroesophageal reflux disease (GERD) results from the backflow of stomach acid, pepsin, or bile salts into the esophagus, leading to inflammation known as esophagitis. This reflux occurs primarily due to irregularities or weakening of the lower esophageal sphincter (LES), which normally acts as a barrier to prevent reflux (McCance & Huether, 2018). Risk factors for GERD include obesity, pregnancy, smoking, hiatal hernia, and the use of certain medications such as antihistamines, calcium channel blockers, antidepressants, and sedatives (Cheng et al., 2021).

Analyzing the patient's symptoms suggests that he exhibits features characteristic of PUD. The patient reports epigastric burning, weight loss, and an occasional dry cough at night, which are hallmark symptoms of peptic ulcers. Furthermore, his history of daily aspirin intake and alcohol consumption are significant risk factors that predispose him to develop gastric mucosal erosion and ulcers (Salsabila et al., 2021). His symptom of epigastric pain and burning aligns with the typical presentation of PUD caused by mucosal damage and acid secretion.

H. pylori infection also plays a critical role in PUD's pathogenesis, with the bacteria promoting increased gastric acid secretion by stimulating gastrin release and disrupting normal gastrointestinal motility (Salsabila et al., 2021). Patients infected with H. pylori often present with epigastric pain, nausea, early satiety, and sometimes vomiting, all of which align with the patient's complaints. Moreover, H. pylori is associated with increased risk of gastric carcinogenesis if untreated, emphasizing the importance of accurate diagnosis and management (McCance & Huether, 2018).

Contrastively, while GERD's symptoms include heartburn, sore throat, regurgitation, and chest discomfort, the patient's predominant symptoms do not heavily emphasize these features. The absence of frequent acid regurgitation or typical chest burning supports the likelihood that his symptoms are more consistent with PUD rather than GERD. Although GERD can sometimes cause chronic coughs and chest discomfort, the combination of epigastric discomfort, weight loss, and risk factors such as NSAID use and alcohol intake point more strongly toward PUD.

In conclusion, the clinical presentation—epigastric burning, weight loss, NSAID use, alcohol consumption, and symptoms related to mucosal erosion—most closely aligns with peptic ulcer disease. The pathophysiology involving mucosal damage driven by acid and H. pylori infection underscores the importance of targeted treatment strategies, including eradication of H. pylori, acid suppression therapy, and lifestyle modifications to prevent complications such as perforation or bleeding.

Peptic ulcer disease (PUD) and gastroesophageal reflux disease (GERD) are two common gastrointestinal conditions that involve mucosal injury caused by acidic gastric contents, but they differ significantly in their pathophysiology, risk factors, and clinical presentations. Understanding their distinctions is fundamental in accurate diagnosis and effective management.

The pathophysiology of PUD primarily involves an imbalance between aggressive factors such as gastric acid, pepsin, and H. pylori infection, and defensive factors like the mucosal barrier, bicarbonate secretion, and mucosal blood flow. In PUD, the erosion of the mucosal layer in the stomach or duodenum results from sustained acid exposure damaging the mucosa over time (McCance & Huether, 2018). When the mucosa's defenses are overwhelmed, ulcers form, which can extend into the muscularis mucosae, leading to complications including hemorrhage and perforation. H. pylori infection plays a central role in PUD's pathogenesis, promoting inflammation and increasing gastric acid secretion through stimulation of gastrin release, disrupting gastrointestinal motility, and impairing mucosal defenses (Salsabila et al., 2021). The bacteria's colonization of the gastric lining also perpetuates mucosal injury, making eradication therapy a key component of treatment.

In contrast, GERD results from a dysfunctional lower esophageal sphincter (LES) that allows gastric contents, primarily acid and pepsin, to reflux into the esophagus. This reflux causes irritation and inflammation, leading to symptoms such as heartburn, sore throat, and regurgitation. The primary mechanism involves transient relaxation or weakening of the LES, which can be affected by various factors including obesity, pregnancy, smoking, and certain medications such as antihistamines and calcium channel blockers (Cheng et al., 2021). Unlike PUD, GERD does not typically involve mucosal ulceration but rather inflammation of the esophageal lining due to acid injury. The backflow of acidic contents in GERD results in symptoms that are predominantly related to esophageal inflammation and irritation.

Clinically, the patient's symptoms—including epigastric burning, weight loss, and a history of NSAID and alcohol use—are more indicative of PUD. Epigastric pain is a hallmark of ulceration, and weight loss suggests possible complication or significant mucosal damage. The daily aspirin use and alcohol consumption are important risk factors for gastric mucosal injury, as both can impair mucosal defenses and increase acid production (McCance & Huether, 2018). The presence of an occasional dry cough at night could be related to aspiration of refluxed gastric contents; however, this is more characteristic of GERD and is less specific.

The literature supports the clinical distinctions: patients with H. pylori infection often present with epigastric pain, fullness, nausea, and early satiety—symptoms consistent with the patient’s complaints (Salsabila et al., 2021). Conversely, GERD is typically characterized by heartburn, regurgitation, sore throat, and chest discomfort, with less association to H. pylori infection. Since the patient's predominant symptoms and risk factors align with the presentation of PUD, it is reasonable to conclude that he most closely represents a case of peptic ulcer disease.

In summary, while both conditions involve acid-related mucosal injury, the differences in their pathophysiology—erosion due to hyperacidity and infection versus reflux-induced esophageal inflammation—underpin their distinct clinical features. Proper diagnosis requires understanding these mechanisms, and treatment should be tailored accordingly, including eradication of H. pylori in PUD and lifestyle modifications for GERD.
