Study Notes
Gastrointestinal Disorders Overview
- Gastroesophageal Reflux Disease (GERD) can lead to Barrett’s esophagus, increasing the risk of esophageal adenocarcinoma.
- Symptoms of GERD include heartburn, sour taste in the mouth, hoarseness, cough, asthma symptoms, bad breath, ear aches, and increased saliva production.
- Gastritis refers to inflammation of the stomach lining, which can be acute or chronic and may be caused by factors such as H. pylori infections, autoimmune reactions, alcohol, tobacco, or NSAIDs.
- Chronic gastritis can lead to mucosal atrophy, metaplasia, and an increased risk of gastric cancer and peptic ulcer disease.
- Autoimmune metaplastic atrophic gastritis can lead to pernicious anemia due to the destruction of gastric parietal cells.
- Peptic Ulcer Disease affects approximately 10%-17% of the population and can lead to bleeding or perforations, with NSAIDs and H. pylori as major risk factors.
- NSAIDs inhibit cyclo-oxygenase enzymes, leading to reduced prostaglandin production and increased susceptibility to ulceration.
- Helicobacter pylori, a gram-negative bacterium, infects approximately 50% of the world's population and is linked to gastritis and peptic ulcer disease.
- H. pylori secretes urease to neutralize stomach acid, adheres to epithelium, and promotes inflammation while impairing the immune response.
- H. pylori eradication dramatically reduces the rate of ulcer recurrence, and untreated infections can persist throughout an individual’s lifetime.
- H. pylori secretes factors that impair the immune response and is associated with the majority of gastric adenocarcinomas and lymphomas.
- H. pylori pathogenesis involves toxins like VacA and mucinase, and inflammation from immune cells that damage the epithelial barrier.
