Stomach Disorders | Clinical Medicine

Gastritis involves inflammation of the stomach lining, primarily affecting the mucosa, with causes including NSAID use and Helicobacter pylori infection, leading to symptoms like epigastric pain and shallow erosions. Peptic ulcer disease, characterized by deeper ulcers and various complications such as GI bleeding and perforation, necessitates prompt diagnosis and treatment, often utilizing proton pump inhibitors and antibiotics for H. pylori eradication.
Insights
- Gastritis is an inflammation of the stomach lining, primarily affecting the mucosa, and is characterized by shallow erosions that do not penetrate deeper than the muscularis mucosa, distinguishing it from more severe conditions like peptic ulcers, which can extend into the submucosa and cause more significant complications.
- Helicobacter pylori infection plays a crucial role in the development of both gastritis and peptic ulcer disease by increasing gastrin production, which leads to elevated hydrochloric acid levels, contributing to mucosal damage and inflammation; this bacterium also produces urease, which alters the stomach's pH and enhances its survival while harming the mucosal cells.
- Effective treatment for gastritis and peptic ulcer disease centers on reducing stomach acid through proton pump inhibitors (PPIs) and addressing H. pylori infections with a combination therapy known as CAP, which includes antibiotics and PPIs; timely diagnosis and management of complications like GI bleeding or perforation are essential to prevent serious health risks.

Recent questions
What is gastritis?
Gastritis is the inflammation of the stomach lining, primarily affecting the mucosa. It often occurs in the antrum of the stomach, where small erosions can develop. These erosions are typically shallow and do not penetrate deeper than the muscularis mucosa, which distinguishes gastritis from peptic ulcers that extend into the submucosa. Symptoms of gastritis may include epigastric abdominal pain, and the condition can be caused by various factors, including the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and infections like Helicobacter pylori.
How to treat peptic ulcer disease?
Treatment for peptic ulcer disease primarily focuses on reducing hydrochloric acid production through acid suppression therapy, typically using proton pump inhibitors (PPIs). These medications help alleviate symptoms and promote healing of the ulcer. In cases where Helicobacter pylori infection is present, a combination therapy known as CAP is often employed, which includes clarithromycin, amoxicillin, and a PPI. For patients allergic to penicillin, alternatives like metronidazole may be used. Additionally, medications such as sucralfate can be administered to enhance the protective alkaline mucus barrier in the stomach.
What causes gastric outlet obstruction?
Gastric outlet obstruction (GOO) can occur as a complication of peptic ulcer disease, primarily due to intense antral fibrosis and edema. This condition leads to a narrowing of the passage from the stomach to the duodenum, resulting in symptoms such as severe abdominal pain, massive gastric dilation, and profound vomiting. A key diagnostic sign for GOO is the presence of a succussion splash, which can be detected through auscultation over the epigastric area, indicating fluid movement against an obstructed outlet. Prompt diagnosis and treatment are essential to alleviate symptoms and prevent further complications.
What are the symptoms of peptic ulcers?
Symptoms of peptic ulcers can vary depending on the type of ulcer present. Patients with gastric ulcers often experience increased epigastric pain when food is consumed, while those with duodenal ulcers typically find that their pain decreases after eating, only to return a few hours later as hydrochloric acid enters the duodenum. Other common symptoms may include nausea, vomiting, and in severe cases, complications such as gastrointestinal bleeding, which can manifest as hematemesis (vomiting blood) or melena (black, tarry stools). Monitoring for these symptoms is crucial for timely intervention.
How is H. pylori diagnosed?
Diagnosis of Helicobacter pylori (H. pylori) infection typically involves non-invasive methods such as the urea breath test and stool antigen tests. The urea breath test is particularly effective, as it measures CO2 levels in the breath after the patient ingests urea, which H. pylori converts to ammonia and CO2. In cases with alarm features, such as significant weight loss or gastrointestinal bleeding, an esophagogastroduodenoscopy (EGD) may be performed to directly assess the stomach lining and obtain tissue samples for microscopic examination. This comprehensive approach ensures accurate diagnosis and appropriate treatment.
