You may have heard of diverticulitis, been diagnosed with it, or your GP might suspect it; and you’re wondering when it’s serious enough to see a gastroenterologist. If you’ve had pain, bloating, or sudden changes in your bowel habits, it’s normal to have questions.
Before we get into when to seek help, let’s quickly clear up what diverticulitis actually is and whether it’s the same as diverticulosis.

Diverticulosis vs diverticulitis? What’s the difference?
Diverticulosis happens when small pouches, called diverticula, form in the lining of your colon. This usually develops over time, especially as we get older. Most people with diverticulosis never know they have it. It’s often found incidentally during a colonoscopy for something else.
It usually doesn’t cause any symptoms, though some people might notice bloating or changes in their bowel habits. But on its own, it’s not dangerous.

But when those pouches do become inflamed or infected, that’s when we call it diverticulitis. This is where the symptoms begin; pain, often sudden and sharp, typically shows up in the lower left side of your abdomen.
You might also feel bloated, nauseous, or slightly feverish. Bowel habits can change too; some people become constipated, while others have looser or more urgent bowel movements.
What does diverticulitis feel like?
It often feels like a sharp or cramping pain in the lower left side of your belly. Some people describe it as a constant ache that worsens over time. You may also feel bloated, sluggish, or a bit feverish.
What does poop look like with diverticulitis?
It can vary. Some people notice their stool becomes loose or more urgent; others might be constipated. You might also see mucus or a change in colour. Blood is not common but should always be checked if it appears.
How diverticulitis is treated (and when to see a doctor)
If you’re having a diverticulitis flare, your first step is usually a visit to your GP. They’ll assess your symptoms, check for signs of infection, and may start you on antibiotics. For many people, that’s enough to settle things down. Rest, simple pain relief, and a temporary change in diet often do the trick.
But if the pain is severe; if you have a fever; or if the symptoms aren’t improving after a few days, it may be time to take the next step. That’s where a gastroenterologist comes in.
At Westside Gastroenterology in Murdoch, we specialise in gut health and can help manage diverticulitis with a personalised plan tailored to you.
Dr Callum Pearce
Gastroenterologist Perth
Seeing a gastroenterologist means going beyond short-term treatment. Once your symptoms are under control, we look at the bigger picture: what triggered the flare, whether there’s any ongoing inflammation, and how to reduce the chance of it happening again.
We may recommend a colonoscopy (once the inflammation has settled) to assess the health of your bowel, check for diverticulosis, and rule out other possible causes of your symptoms, like polyps or bowel cancer.

How do you treat diverticulitis?
Mild episodes are treated with antibiotics, rest, and a liquid or soft diet. We avoid fibre at first to give the gut a break. If you’re not improving or you develop complications, hospital care may be needed.
How to relieve diverticulitis pain fast?
Fast relief usually comes from resting your digestive system. Stick to clear fluids, follow your antibiotic plan, and use simple pain relief like paracetamol. A heat pack on the belly can help too.
Does diverticulitis go away?
Yes; most people recover fully with treatment. However, repeated diverticulitis flares may require further tests or long-term management to prevent future issues.
How long does diverticulitis last?
Mild cases often improve within 3 to 5 days. More severe or recurrent cases may take a week or longer, especially if complications develop.
