Irritable Bowel Syndrome (IBS) is one of the most commonly diagnosed digestive disorders, yet many people may receive this label when another underlying condition is actually responsible for their symptoms.

IBS is a functional disorder, meaning no structural abnormality is present, and diagnosis relies on symptom patterns and ruling out other conditions. But with overlapping symptoms, conditions such as Coeliac disease, SIBO, inflammatory bowel disease, microscopic colitis, and food intolerances can sometimes be mistaken for IBS.

Stress and lifestyle factors play a big role too. Anxiety, poor sleep, diet, and high-stress levels can trigger IBS-like symptoms, further complicating accurate diagnosis.

What this means for patients:

➡️ A thorough assessment by a gastroenterologist is essential
➡️ Tests, dietary review, and lifestyle evaluation can help rule out other causes
➡️ Understanding the gut-brain connection is key to addressing symptoms

IBS is real and can impact quality of life, but careful evaluation ensures the right diagnosis and the most effective approach to treatment.

Many people confuse colonoscopy and endoscopy / gastroscopy, but they serve different purposes.

Colonoscopy: Examines the lower gastrointestinal tract — the colon, large bowel, or large intestine. It’s commonly used to detect polyps, colorectal cancer, inflammation, and other conditions affecting the lower gut.

Endoscopy / gastroscopy: Examines the upper digestive tract, including the oesophagus, stomach, and small intestine. This procedure helps diagnose conditions like ulcers, reflux, and upper GI bleeding.

Understanding the difference can help you know which procedure is recommended for your symptoms or screening needs. Both are important tools in maintaining digestive health and detecting issues early.

If you receive a positive screening test result, the next step is to have a blood test and colonoscopy.

If your result is negative, meaning no blood was detected in your samples, this does not guarantee you are free from bowel cancer now or in the future. It is important to stay vigilant, watch for any symptoms, and repeat the screening test in two years.

While colonoscopy is one of the most effective tools for reducing deaths from bowel cancer, it does have limitations. There is a risk of “missed lesions,” but recent advancements are helping reduce this risk. These include:

➡️ Improved colon preparation
➡️ High-definition wide-angle colonoscopes and video technology
➡️ Carbon dioxide insufflation
➡️ Retroflexion to examine behind folds
➡️ Careful monitoring of withdrawal time and adenoma detection rates

These developments strengthen the role of colonoscopy in preventing bowel cancer deaths.

The key message remains: Early detection and intervention offer the greatest chance of survival.
