A colonoscopy is a procedure in which a doctor uses a flexible tube with a camera to examine the inner lining of the colon and rectum. It is a vital tool for detecting colorectal cancer, as well as other issues like polyps, ulcers, and inflammation. A colonoscopy is typically recommended for individuals aged 50 and older. However, a colorectal specialist may recommend an earlier screening if you have specific intestinal problems or other risk factors for colorectal cancer. Early detection through a colonoscopy can significantly improve treatment outcomes and prevent serious complications.

Below are five warning signs that may indicate the need for a colonoscopy, along with their possible implications and why this procedure is important:

Persistent changes in bowel patterns, such as diarrhoea, constipation, or the presence of thinner, ribbon-like stools, are often the first signs of potential colon issues. These changes may be caused by conditions like infections, inflammatory bowel disease (IBD), or even colorectal cancer. A colonoscopy can help pinpoint the root cause, such as inflammation, blockages, or abnormal growths, for timely treatment.

Blood in the stool, whether bright red or darker, is a symptom that should never be overlooked. Rectal bleeding may result from haemorrhoids, anal fissures, or more serious conditions like diverticulitis or colorectal cancer. Through a colonoscopy, doctors can visualise the inside of the colon and identify the source of bleeding. Tissue samples may be taken for further analysis if any abnormal growths or inflamed areas are found.

Losing weight without intentional changes to diet or exercise can be concerning, particularly when accompanied by other problems in the colon. Colon cancer or other severe digestive disorders can affect the body’s ability to absorb nutrients properly. A colonoscopy can help detect abnormalities, such as tumours, that may be linked to unexplained weight loss.

Persistent or recurring abdominal pain, cramping, or bloating may signal underlying issues in the colon, such as inflammation, diverticulitis, or growths. While some causes are benign, others require medical intervention. A colonoscopy is an effective way to investigate the cause of abdominal pain, providing a detailed view of the colon lining.

Feeling unusually weak or fatigued can be a subtle sign of severe issues with the gastrointestinal tract. In some cases, colorectal cancer causes slow internal bleeding, which gradually leads to iron-deficiency anaemia. As iron levels decrease, individuals may experience exhaustion, dizziness, or shortness of breath. A colonoscopy can provide valuable insights and guide treatment to improve health and energy levels.

For individuals at high risk, ignoring symptoms such as bowel habit changes, rectal bleeding, and unexplained weight loss may delay the diagnosis of potentially severe colorectal conditions. A colonoscopy is a crucial diagnostic tool that can significantly improve outcomes and reduce the risk of advanced disease.
