GERD involves stomach contents refluxing into the esophagus. Gastritis is inflammation of the stomach lining. Similar discomfort does not make them the same diagnosis.
GERD centers on reflux into the esophagus
GERD can cause heartburn and regurgitation, as well as chest discomfort, cough, or swallowing symptoms. It reflects a recurring reflux problem rather than inflammation of the stomach lining itself.
Gastritis affects the stomach lining
Gastritis can be caused by Helicobacter pylori infection, certain medicines such as NSAIDs, alcohol, autoimmune disease, and other factors. Evaluation and treatment depend on the cause; a trigger-food search cannot diagnose it.
- Upper-abdominal pain or discomfort can occur in gastritis.
- Nausea, vomiting, appetite changes, or early fullness may occur.
- Bleeding can cause black or tarry stool or vomit that looks bloody or like coffee grounds.
Overlapping symptoms need context
Avoid assuming every upper-digestive symptom is GERD. If symptoms are new, persistent, severe, or include bleeding, swallowing difficulty, persistent vomiting, loss of appetite, or unexplained weight loss, seek medical care.
