Key Takeaways

Your bowel habit is personal — what's 'normal' for one person is different for another. What matters clinically is a genuine, persistent change from your own baseline: new or worsening constipation, looser or more frequent stools, urgency, or alternating patterns, lasting more than around six weeks without an obvious explanation like a change in diet, medication, or a short-lived stomach bug.

Common Causes

Why See a Surgeon-Endoscopist for GI Symptoms

Most GI symptoms are first assessed by a gastroenterologist — a physician who diagnoses and manages digestive conditions medically. Mr Papettas offers a complementary route: as a Consultant Colorectal & General Surgeon who also holds JAG dual accreditation in colonoscopy and gastroscopy, he can take your history, examine you, perform the relevant endoscopic investigation himself, and — if a surgical problem is found — move straight to planning treatment, without a separate referral cycle. For symptoms that may ultimately need a surgical opinion (persistent pain, a mass, bleeding, hernia-related symptoms, or a diagnosis that turns out to need an operation), this can mean one consultant relationship from first appointment to treatment, rather than several.

What Happens at Your Consultation

  1. A detailed history and examination — the majority of GI symptoms are significantly clarified by this alone.
  2. Where indicated, same-consultant access to colonoscopy and/or gastroscopy, avoiding a separate referral for endoscopy.
  3. Blood tests or imaging arranged directly where needed (e.g. iron studies, ultrasound, CT).
  4. A clear diagnosis and management plan explained in the same relationship — through to surgery, if that turns out to be the right next step.

Frequently Asked Questions

What counts as a 'change in bowel habit'?

It means a persistent, unexplained shift away from what's normal for you — for example, new or worsening constipation, looser or more frequent stools, or alternating between the two — lasting more than around six weeks, rather than a short-lived episode linked to diet, travel, or a stomach bug.

Why do doctors take this symptom seriously?

Because a persistent, unexplained change in bowel habit — particularly in people over 50, or alongside rectal bleeding, weight loss, or anaemia — is one of the recognised features that prompts urgent investigation to rule out bowel pathology, including bowel cancer. Most cases turn out to have a benign cause (IBS, diet, medication), but the symptom itself always merits assessment rather than being dismissed.

What investigation will I need?

A colonoscopy is the standard way to directly examine the bowel lining when change in bowel habit needs investigating, particularly with any red-flag features. Mr Papettas performs this himself as a JAG dual-accredited endoscopist, with a near-100% caecal intubation rate (meaning the scope reliably reaches and examines the full colon).

Is it likely to be something serious?

Most persistent bowel habit change turns out to be due to IBS, diet, medication side-effects, or diverticular disease rather than cancer — but the only way to know is proper assessment, particularly given how treatable bowel cancer is when caught early.

What's the difference between IBS and a more serious cause?

IBS is typically a longer-standing pattern without weight loss, bleeding, or anaemia, often linked to stress or specific foods. New-onset change after 50, or any change alongside bleeding, weight loss, or a palpable lump, is treated differently and investigated promptly. See the IBS vs IBD page for more on how these are distinguished.

How soon can I get a colonoscopy privately?

Typically within a week or two of consultation at Nuffield Health Warwickshire Hospital, Leamington Spa, with the same consultant carrying out both the assessment and the procedure.
