Safety

When to seek urgent medical advice

If you experience any of the following, seek prompt medical attention:

• Vomiting blood
• Black stools
• Severe abdominal pain
• Persistent vomiting
• Unexplained weight loss
• Difficulty swallowing

• Symptoms of dehydration
• Severe weakness or fainting

If symptoms are severe or urgent, attend the nearest emergency department. This website is not for emergency care.

Bowel cancer screening

Bowel Cancer Screening Matters

Colonoscopy is commonly used to investigate bowel symptoms, detect polyps, and screen for bowel cancer in appropriate patients. Early detection can improve outcomes — patients with a family history, previous polyps, rectal bleeding, unexplained anaemia, or change in bowel habit should seek medical advice.

Patient education

Common topics, simply explained

Reflux & Heartburn

Persistent reflux that doesn't settle with medication, or which is associated with swallowing difficulty, weight loss, or anaemia, often warrants gastroscopy assessment.

H. pylori & Gastritis

Inflammation of the stomach lining can cause pain, nausea, and ulcers. Gastroscopy allows visualisation and testing for H. pylori infection.

Anaemia

Unexplained iron deficiency anaemia may indicate slow GI blood loss. Gastroscopy and colonoscopy help identify the source.

Rectal Bleeding

Bleeding from the rectum should never be dismissed. Colonoscopy can identify causes ranging from haemorrhoids to polyps or more serious conditions.

Change in Bowel Habit

A persistent change in bowel habit lasting more than a few weeks — particularly in adults over 40 — warrants assessment.

Polyps & Bowel Cancer Screening

Polyps are common and can sometimes develop into cancer over time. Detection and removal during colonoscopy reduces this risk.
