General patient information

Symptoms, alarm symptoms and when to contact a doctor

General information about gastrointestinal symptoms. This page does not calculate a result from your answers and does not point to a specific investigation.

This page is general information. You cannot enter your own symptoms and receive an individual assessment or a recommendation for a specific investigation. Which assessment is relevant depends on symptoms, duration, age, family history, previous investigations and the overall clinical picture - and is decided by the doctor during the consultation.

Alarm symptoms - contact a doctor

  • Visible blood in the stool, or black, tarry stools.
  • Unexplained weight loss.
  • Difficulty swallowing or persistent vomiting.
  • Anaemia without a known explanation.
  • Fever or night-time symptoms that wake you.
  • New persistent symptoms after the age of 50.
  • A close relative with bowel cancer or inflammatory bowel disease.

For acute or severe symptoms - such as significant bleeding, severe abdominal pain or feeling generally unwell - contact your doctor, an out-of-hours service or emergency services. An alarm symptom does not automatically mean endoscopy; it means a doctor needs to assess the context.

Common symptoms often discussed in the consultation

  • Bloating and wind.
  • Abdominal pain or discomfort that comes and goes.
  • A change in bowel habit - frequency or consistency.
  • Symptoms that change after meals.
  • Bad breath (halitosis), which most often originates in the mouth.

What you can prepare before a consultation

  • How long the symptoms have lasted and how they have developed.
  • Whether any alarm symptoms have occurred.
  • Previous investigations, diagnoses, operations and current medication.
  • Gastrointestinal disease in close relatives.
