Gastritis: When Your Stomach Lining Is Inflamed

Burning stomach pain, nausea, and bloating after meals could be gastritis — inflammation of the stomach lining. A clear guide to the causes, relief, and when stomach symptoms need a doctor.

Burning or gnawing pain in the upper stomach, nausea, bloating, or feeling full quickly — these are the hallmarks of gastritis, inflammation of the stomach lining. It's extremely common, especially in India, and while it's usually not serious, it can be uncomfortable and, left unchecked, sometimes leads to ulcers. The good news is it responds well to treating the cause and some simple changes. This is a clear, plain-language guide to gastritis. (It overlaps with acidity and reflux — see those guides too.)

What Is Gastritis?

Gastritis means the lining of the stomach is inflamed or irritated. It can be sudden (acute) or long-standing (chronic). Normally the stomach lining is protected from its own acid; when that protection is disturbed or the lining is irritated, you get the burning, nausea, and discomfort. It's related to — but not the same as — a peptic ulcer (an actual sore); untreated gastritis can sometimes progress toward one.

Common Causes

  • H. pylori infection — a common stomach bacterium (also a leading ulcer cause)
  • Regular painkillers (NSAIDs) like some anti-inflammatory tablets
  • Alcohol, smoking, and very spicy/oily food (can irritate/aggravate)
  • Stress (including physical stress from serious illness)
  • Skipping meals, excessive tea/coffee on an empty stomach
Often it's H. pylori or painkillers — not just "spicy food" People blame spicy food, and while it can aggravate symptoms, two of the biggest true causes are the H. pylori bacterium and regular NSAID painkillers. That matters, because treating those (antibiotics for H. pylori, reviewing painkillers) is what actually resolves gastritis — not just cutting chillies.

Symptoms

  • Burning or gnawing pain in the upper abdomen
  • Nausea, sometimes vomiting
  • Bloating, feeling full quickly, or indigestion
  • Loss of appetite
  • Symptoms often worse on an empty stomach or after trigger foods
Warning signs — seek prompt/urgent care
  • Vomiting blood, or vomit like coffee grounds
  • Black, tarry stools (a sign of bleeding)
  • Severe or persistent stomach pain, or unexplained weight loss
  • Difficulty swallowing, or symptoms in an older adult that are new

How It's Managed

  • Treat the cause — antibiotics if H. pylori is found; stop/change NSAIDs where possible
  • Acid-reducing medicines as advised, to let the lining heal
  • Ease off alcohol, smoking, and known trigger foods
  • Eat regular, smaller meals; avoid long empty-stomach gaps
  • Manage stress

When to See a Doctor

See a doctor or gastroenterologist for persistent or recurring upper-stomach burning, nausea, or indigestion — because treating the underlying cause (like H. pylori, or a painkiller) is what truly resolves it, and simple antacids alone often aren't enough. Treat vomiting blood, black stools, or severe pain as urgent. An online consultation is a good first step to describe symptoms, arrange testing (like for H. pylori), and get the right treatment. (See our guides on acidity/heartburn, chronic acid reflux/GERD, peptic ulcer, and using antibiotics wisely.)

A note on sources General education based on trusted public health and gastroenterology sources (NHS, NIH). It does not replace an assessment by a doctor, who diagnoses the cause and treats gastritis.
