Diverticular Disease: Symptoms & Treatment

Small pouches in the bowel wall are extremely common with age and usually silent — but when they cause symptoms or complications, proper assessment matters.

Key Takeaways

Diverticula are small, pea-sized pouches that develop in the wall of the large bowel over time, almost always in the lower left side (sigmoid colon). They're a normal feature of an ageing bowel — most people who have them never know, and never develop symptoms. Diverticular disease describes the minority of cases where these pouches cause pain or altered bowel habit; diverticulitis is the more acute situation where one becomes inflamed or infected.

Seek Urgent Medical Review If You Have

Seek prompt (same-day, if severe) assessment for suspected diverticulitis with:

How It's Managed

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.

Because diverticular disease sits right at the boundary between medical and surgical management, having one consultant who can do both avoids being passed between teams if a flare becomes recurrent or complicated.

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 is diverticular disease?

Diverticula are small pouches that form in the wall of the large bowel, most often in the lower left side (sigmoid colon). Having them without symptoms is called diverticulosis and is extremely common with age — by 60, roughly half of people have some. Diverticular disease refers to when these pouches cause symptoms; diverticulitis is when one or more become inflamed or infected.

What are the symptoms?

Typically left-sided lower abdominal pain, altered bowel habit, and bloating. Diverticulitis (inflammation) causes more acute, often severe pain, usually with fever and sometimes nausea, and needs prompt medical attention.

How is it diagnosed?

Colonoscopy is commonly used to confirm diverticula and rule out other causes of symptoms, though it's usually avoided during an acute flare of diverticulitis. CT scanning is the preferred investigation during an acute episode.

Does diverticular disease need surgery?

Most cases are managed with diet, lifestyle measures and, for flares, antibiotics or other medical treatment — surgery is reserved for recurrent or complicated diverticulitis (such as an abscess, perforation, or stricture), or where symptoms significantly affect quality of life despite medical management.

Can diverticular disease cause bleeding?

Yes — diverticular bleeding can be sudden and sometimes significant, though it often settles on its own. Any diverticular bleeding should still be assessed; see the rectal bleeding page.

Is diverticular disease linked to bowel cancer?

No direct causal link, but because the symptoms can overlap with other bowel conditions, colonoscopy is often used to confirm the diagnosis and exclude other causes, particularly if symptoms are new.
