Understanding common benign conditions of the stomach

What are benign gastric diseases?

These are non-cancerous conditions of the stomach. The common examples are:

• Gastritis: inflammation of the stomach lining, often from infection (Helicobacter pylori), excessive alcohol, or NSAID medication.
• Peptic ulcers: open sores on the lining of the stomach or upper small intestine, usually from H. pylori infection or prolonged NSAID use.
• Gastric polyps: small growths on the stomach lining, usually harmless but sometimes needing removal.
• Gastroparesis: the stomach empties too slowly, often related to diabetes or nerve damage.

What are the symptoms?

• Upper abdominal pain or discomfort.
• Nausea or vomiting.
• Loss of appetite or unintentional weight loss.
• Bloating, or fullness after small meals.
• Heartburn or indigestion.
• Black or tarry stools, which may indicate a bleeding ulcer.

How are they diagnosed?

• Endoscopy: a flexible camera inserted into the stomach to visualise the lining and detect ulcers or polyps.
• Biopsy: a tissue sample taken during endoscopy to rule out infection, inflammation or malignancy.
• Imaging: X-ray, CT or barium swallow to detect structural problems.
• Laboratory tests: blood, stool or breath tests to check for H. pylori.

What are the treatment options?

• Antibiotics to eradicate H. pylori in gastritis or peptic ulcer.
• Proton pump inhibitors (PPIs) to reduce stomach acid and let ulcers heal.
• Antacids to relieve heartburn.
• Prokinetic agents for gastroparesis, to improve stomach emptying.
• Dietary and lifestyle change: avoiding spicy, acidic or greasy food; reducing alcohol and caffeine; eating smaller, more frequent meals.
• Polypectomy: removal of gastric polyps during endoscopy.

When is surgery required?

Most benign gastric disease is treated medically. Surgery becomes necessary in cases of:

• Persistent or recurrent bleeding from ulcers.
• Perforation — a hole in the stomach wall.
• Obstruction caused by scarring or polyps.
• Severe gastroparesis not responding to medical management.

What is recovery like after surgery?

• Hospital stay: most patients stay a few days.
• Diet: a gradual transition from liquids to solid food, with longer-term modification as needed.
• Activity: light activity within 1–2 weeks; avoid strenuous activity for 4–6 weeks.

Can benign gastric disease lead to cancer?

Most do not. However, chronic H. pylori infection, gastritis and large gastric polyps may increase the risk of gastric cancer over time. Regular monitoring and timely treatment reduce that risk substantially.

What lifestyle changes help?

• Eat a balanced diet: whole grains, lean protein and vegetables; avoid highly processed or acidic food.
• Avoid smoking and limit alcohol, both of which irritate the stomach lining.
• Use NSAIDs cautiously, with food or as prescribed.
• Manage stress, which contributes to gastric symptoms.
• Treat underlying conditions such as diabetes, which can lead to gastroparesis.
