Erosive Gastritis: What You Need to Know

What is Erosive gastritis?

Erosive gastritis, also called acute or hemorrhagic gastritis, is an inflammation of the stomach lining that leads to superficial erosions (tiny breaks) in the mucosal surface. Unlike chronic gastritis, which develops slowly and often without obvious bleeding, erosive gastritis appears suddenly and can cause visible blood in the stomach, vomiting, or black, tarry stools. The condition may be self‑limited, but in some people it can progress to ulceration or bleeding that requires urgent care.

Histologically, the lining shows edema, inflammatory cell infiltrates (especially neutrophils), and loss of the protective gastric mucosal barrier. The barrier disruption allows gastric acid and digestive enzymes to damage the underlying tissue, creating the erosions that give the condition its name.

Common Causes

Many factors can damage the gastric mucosa enough to produce erosive gastritis. The most frequent contributors include:

• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – ibuprofen, naproxen, aspirin, and selective COX‑2 inhibitors.
• Excessive alcohol consumption – especially binge drinking.
• Stress‑related mucosal damage – severe physiologic stress such as major surgery, trauma, burns, or septic shock.
• Helicobacter pylori infection – the same bacterium that causes peptic ulcers can trigger acute inflammation.
• Gastric acid hypersecretion – conditions like Zollinger‑Ellison syndrome.
• Corticosteroid therapy – especially when combined with NSAIDs.
• Smoking – nicotine impairs mucosal blood flow and mucus production.
• Chronic vomiting or bulimia nervosa – repeated exposure of the stomach lining to vomit’s acidic contents.
• Radiation therapy to the abdomen – damages rapidly dividing mucosal cells.
• Autoimmune disorders – rare cases linked to systemic lupus erythematosus or vasculitis.

Associated Symptoms

Because erosive gastritis often involves bleeding, the clinical picture can vary from mild discomfort to overt hemorrhage. Commonly reported symptoms are:

• Upper abdominal (epigastric) pain or burning that may improve or worsen after meals.
• Nausea and occasional vomiting; vomitus may contain fresh blood (hematemesis) or look coffee‑ground like.
• Black, tarry stools (melena) indicating digested blood passing through the intestines.
• Loss of appetite and early satiety.
• Generalized weakness or fatigue, especially if blood loss is significant.
• Feeling of fullness after only a few bites of food.
• Occasional low‑grade fever if infection or severe inflammation is present.

When to See a Doctor

Most cases of mild erosive gastritis improve with medication and lifestyle changes, but you should seek medical attention promptly if you experience any of the following:

• Vomiting blood or material that looks like coffee grounds.
• Black, tarry stools or bright red blood per rectum.
• Persistent abdominal pain lasting more than 24 hours.
• Sudden weakness, dizziness, or fainting spells (possible anemia).
• Unexplained weight loss or loss of appetite lasting several weeks.
• Fever above 101 °F (38.3 °C) accompanying gastrointestinal symptoms.

Diagnosis

Evaluation begins with a thorough history and physical exam, followed by targeted tests to confirm erosive gastritis and rule out other conditions.

1. Laboratory Tests

• Complete blood count (CBC) – detects anemia from chronic bleeding.
• Serum electrolytes & renal function – especially important if the patient is on NSAIDs or diuretics.
• Stool guaiac test – screens for occult (hidden) blood.
• Helicobacter pylori testing – breath test, stool antigen, or biopsy‑based.

2. Endoscopic Examination (EGD)

Upper gastrointestinal endoscopy is the gold‑standard. It allows direct visualization of erosions, assessment of bleeding, and biopsy for histology or H. pylori detection. In most cases, the endoscopist will see multiple linear or punctate erosions, sometimes with superficial hemorrhage.

3. Imaging (when needed)

• CT abdomen – reserved for patients with severe abdominal pain or suspicion of perforation.
• Abdominal ultrasound – may help rule out gallbladder disease that can mimic epigastric pain.

Treatment Options

Treatment aims to stop the source of injury, protect the mucosa, and promote healing.

1. Medication

• Proton‑pump inhibitors (PPIs) – omeprazole, esomeprazole, or pantoprazole reduce acid production and are first‑line for most patients (7‑14 days course).
• H2‑blockers – ranitidine (where still available) or famotidine as alternatives or adjuncts.
• Sucralfate – forms a protective coating over erosions; useful when PPIs are contraindicated.
• Antibiotics – triple‑therapy regimens if H. pylori is present (e.g., clarithromycin + amoxicillin + PPI).
• Octreotide – for patients with severe bleeding not responding to endoscopic therapy.
• Iron supplementation – if anemia is identified.

2. Stopping the Offending Agent

Discontinue NSAIDs, aspirin, and alcohol. If an anti‑platelet or anticoagulant is essential, discuss alternatives with a cardiologist or hematologist.

3. Endoscopic Therapy

For active bleeding, endoscopists can apply:

• Thermal coagulation.
• Hemoclips.
• Injection of epinephrine.

4. Lifestyle & Home Care

• Dietary adjustments – small, frequent meals; avoid spicy, fried, or highly acidic foods.
• Hydration – sip water throughout the day; limit caffeine.
• Alcohol moderation – abstain while healing.
• Smoking cessation – improves mucosal blood flow.
• Stress management – yoga, meditation, or counseling can lower physiologic stress.

Prevention Tips

While some risk factors (age, genetics) cannot be changed, most cases of erosive gastritis are preventable with simple measures:

• Use the lowest effective NSAID dose for the shortest possible time; consider acetaminophen for mild pain.
• Take NSAIDs with food or a PPI prophylaxis if long‑term use is unavoidable.
• Limit alcohol to ≤1 drink per day for women and ≤2 for men, or abstain if you have a history of gastritis.
• Quit smoking; resources such as nicotine replacement therapy or counseling increase success rates.
• Maintain a healthy weight – obesity raises intra‑abdominal pressure and can exacerbate reflux.
• Screen and treat H. pylori infection, especially before beginning long‑term NSAID therapy.
• Manage stress through regular exercise, adequate sleep, and relaxation techniques.
• If you require chronic steroids, discuss gastro‑protective strategies (PPIs or H2‑blockers) with your physician.

Emergency Warning Signs

Key Take‑aways

Erosive gastritis is an acute inflammation of the stomach lining that can cause painful ulcer‑like erosions and bleeding. Early recognition, removal of the offending agents, and appropriate acid‑suppressive therapy usually lead to full recovery. However, because bleeding can be hidden or catastrophic, it is essential to seek prompt medical attention when warning signs appear.
