Definition
- Gastritis: Inflammation of the stomach lining, which can be acute or chronic and caused by various factors.
- Peptic Ulcer: Refers to an open sore on the lining of the stomach (gastric ulcer) or the first part of the small intestine (duodenal ulcer).
- Helicobacter pylori (H. pylori): A bacterium that lives in the stomach lining and is often associated with gastritis and peptic ulcers.
Pathogenesis
- Gastritis: Can result from exposure to toxic substances (e.g., alcohol, smoking), medications (NSAIDs), infections, autoimmune disorders, or stress.
- Peptic Ulcer: Occurs when the balance between digestive fluids and the protective mechanisms of the stomach lining is disrupted. Often linked to H. pylori infection and prolonged use of anti-inflammatory medications.
Diagnosis
- Gastritis and Peptic Ulcer: Diagnosed through endoscopy and biopsy of the stomach lining.
- H. pylori: Diagnosed using breath tests, blood tests, stool tests, or samples obtained during endoscopy.
Treatment
- Gastritis and Peptic Ulcer:
- Medications to reduce acid production, such as proton pump inhibitors (PPIs).
- For H. pylori infection, eradication therapy using antibiotics.
- Lifestyle changes, including dietary management, avoiding alcohol and smoking, and reducing stress.
Regular medical follow-up is crucial to effectively manage the condition and prevent complications.
