“Gastritis” cannot be confirmed from symptoms alone. In a 28-year-old with 14 days of upper-abdominal burning that began with heartburn and is worse later in the day, acid reflux (GERD) or uninvestigated dyspepsia is more likely than a dangerous cause, but peptic ulcer disease, H. pylori infection, or irritation from alcohol/NSAID painkillers can also cause this pattern. Heartburn as the predominant symptom particularly points toward reflux. Harrison’s Principles of Internal Medicine, p. 2533.
What to do now
- Arrange a primary-care visit soon, particularly since symptoms are increasing rather than settling.
- A clinician may offer a 4-week course of a proton-pump inhibitor (PPI) and/or arrange noninvasive H. pylori testing. Current NICE guidance supports both an empirical 4-week full-dose PPI trial and a “test-and-treat” approach for H. pylori in uninvestigated dyspepsia. If a breath or stool test is planned, PPIs need to be stopped for 2 weeks before testing to avoid a false-negative result: NICE recommendations.
- Avoid ibuprofen, diclofenac, naproxen, aspirin and similar anti-inflammatory pain medicines unless a clinician specifically says otherwise. Avoid alcohol and smoking/vaping if applicable.
- For the next 1 to 2 weeks: smaller evening meals; avoid lying down for 3 hours after eating; reduce trigger foods if they clearly aggravate symptoms, commonly spicy/fatty meals, tea/coffee, chocolate, mint, citrus, and carbonated drinks; elevate the head of the bed if symptoms occur at night.
- An over-the-counter antacid/alginate after meals or at bedtime may give short-term relief. Check with a pharmacist if taking other medicines.
Seek urgent care today if there is black/tarry stool, vomiting blood or coffee-ground material, fainting, severe or worsening abdominal/chest pain, repeated vomiting, difficulty or pain on swallowing, unintentional weight loss, or marked fatigue/pallor. Alarm features such as weight loss, obstruction symptoms, gastrointestinal bleeding, or iron-deficiency anemia warrant prompt endoscopy assessment. Harrison’s Principles of Internal Medicine, p. 2533.
Useful details to tell the clinician: exact site of pain, relation to meals, sour regurgitation, nausea/vomiting, bowel or stool changes, any painkiller use, alcohol/tobacco use, and any history of ulcer or H. pylori treatment.
