The main symptom of indigestion (dyspepsia) is pain or a feeling of discomfort in your chest or stomach.


This usually comes on soon after eating or drinking, although there can sometimes be a delay between eating a meal and experiencing indigestion.


The symptoms of indigestion are often described as ‘heartburn’, which you may experience as a burning pain behind your breastbone. Heartburn is caused by acid that passes from your stomach into your oesophagus (gullet).


If you have indigestion, you may also have symptoms such as:


  • feeling uncomfortably full or heavy

  • belching

  • bringing food back up from your stomach

  • bloating

  • nausea (feeling sick)

  • vomiting

When you should see a doctor


In some cases, indigestion symptoms can indicate a more serious underlying health problem, such as stomach cancer. Seek immediate medical attention if you have recurring indigestion and you:


  • are 55 years old or over

  • have lost a lot of weight without meaning to

  • have increasing difficulty swallowing (dysphagia)

  • have persistent vomiting

  • have iron deficiency anaemia

  • have a lump in your stomach

  • have blood in your vomit or blood in your stools
