Acidity & Gastritis

Burning in the upper abdomen or chest caused by irritation of the stomach lining or acid moving upward.

Overview

Acidity describes the burning discomfort that follows meals, while gastritis refers to inflammation of the stomach lining. The two often occur together and share most of their triggers.

Occasional acidity is common. Symptoms that recur several times a week, or that need frequent over-the-counter antacids, deserve proper assessment.

Symptoms people notice

  • Burning in the upper abdomen or behind the breastbone
  • Sour or bitter fluid rising into the throat
  • Nausea, especially on an empty stomach
  • Belching and a bloated feeling after meals
  • Discomfort that worsens on lying down

Causes and risk factors

  • Long gaps between meals, or eating very late at night
  • Spicy, oily and heavily processed food
  • Tea, coffee and carbonated drinks in excess
  • Frequent painkiller use
  • Smoking, alcohol and ongoing stress
  • H. pylori infection of the stomach lining

When to seek help

Do not wait on these

  • Difficulty or pain on swallowing
  • Vomiting blood, or black tarry stools
  • Weight loss without trying
  • Chest pain — which always needs to be assessed urgently
  • Symptoms that persist despite four weeks of care

Lifestyle and daily guidance

  1. 1Eat smaller portions at fixed times instead of two heavy meals
  2. 2Finish dinner two to three hours before lying down
  3. 3Raise the head of the bed slightly if night symptoms are common
  4. 4Cut back on tea, coffee and smoking
  5. 5Identify and reduce your two or three strongest food triggers

Frequently asked questions

Occasional use is generally fine, but needing them daily is a signal to look for the underlying cause rather than to continue self-medicating.
