When It’s Not IBS: How to Advocate for Your Own Diagnosis

It starts with a bit of bloating. A weird bowel habit. Some cramps. Maybe your poo looks different. You Google the symptoms and end up in a rabbit hole of “gut health” influencers trying to sell you supplements, drinks, and “bloat-free” guides. You mention it to a GP, and they say it’s probably IBS. But what if it’s not?

For too many young Australians, those early symptoms, dismissed as “just IBS” turn out to be something far more serious. Like bowel cancer.

This blog is for anyone who’s been brushed off, told to drink more water, cut out gluten, or just “manage stress.” It’s about how to advocate for your own diagnosis, especially when you feel like something’s wrong and no one’s listening.

Why IBS Gets Thrown Around So Easily

Irritable Bowel Syndrome (IBS) is a real condition. It affects around 1 in 5 Australians and can cause all sorts of symptoms, bloating, diarrhoea, constipation, cramps, urgency, and discomfort.

The problem is, it’s also a “diagnosis of exclusion”. That means IBS is what you’re told when they can’t find anything else wrong. But too often, people (especially young people) are handed that label without proper investigation.

Why? Because:

• You’re “too young” for anything serious (spoiler: you’re not)
• You don’t “look sick”
• Your symptoms overlap with IBS, so doctors make assumptions
• Healthcare is under pressure and it’s quicker to default to a common diagnosis

And while doctors are human and most are doing their best, these shortcuts can delay serious diagnoses like bowel cancer, sometimes for months or even years.

Symptoms That Overlap And Why It Matters

Here’s the kicker: IBS symptoms and early bowel cancer symptoms can look very similar.

Think:

• Changes in bowel habits (more frequent, less frequent, looser, harder)
• Bloating or abdominal discomfort
• Urgency or incomplete emptying
• Mucus in stools
• Tiredness or low energy

The big red flags like bleeding or unexplained weight loss don’t always show up straight away, especially in younger people. So if something feels “off” and you’re not getting answers, you have every right to dig deeper.

The Danger of Self-Diagnosing via Instagram

Let’s call out the social media nonsense while we’re here.

There’s a wave of gut-health marketing that goes something like this:

“Do you have bloating, fatigue, or toilet troubles? It’s probably IBS. Try our $89 supplement and feel better in 7 days!”

These ads are everywhere. They sound science-y. They often include long lists of vague symptoms that make you think, “Yep, that’s me.” But they’re not diagnosing you, they’re selling to you.

The danger is this: You start treating yourself for a condition you’ve never actually been diagnosed with. That’s risky. Because it might not be IBS. And the longer you wait, the more time a serious illness like bowel cancer has to grow undetected.

Don’t let a sponsored post decide your health plan. See a GP first.

How to Advocate for Better Testing

If you’ve been told it’s IBS but something still doesn’t feel right, here’s how to speak up:

1. Track Your Symptoms

Keep a diary of what’s happening, bowel movements, pain, bleeding, bloating, fatigue, anything unusual. Specific examples make it easier for your GP to understand what’s going on.

2. Ask About Red Flags

Say something like: “I know IBS is common, but I’m worried there could be something more serious. Can we rule out bowel cancer or other conditions first?”

3. Request Appropriate Tests

Depending on your symptoms, that might include:

• Faecal Immunochemical Test (FIT) to check for blood in your stool
• Blood tests (to look for anaemia or inflammation)
• Referral to a gastroenterologist
• Colonoscopy if symptoms persist or there are risk factors

4. Don’t Be Afraid to Get a Second Opinion

If your gut says something’s wrong, listen to it. You’re not being difficult, you’re being proactive. Many young patients are only diagnosed after pushing for further tests.

5. Mention Your Family History

If anyone in your family has had bowel cancer, speak up. Even if it’s distant. It matters.

“Too Young” Is Not a Diagnosis

This one deserves its own heading.

You are not too young for bowel cancer. Rates of early-onset bowel cancer (under 50) are rising fast in Australia, and more young people are being diagnosed every year.

So if a doctor ever says “you’re too young for it to be cancer,” remind them that’s not how cancer works. Age doesn’t give you immunity.

Dismissal delays diagnosis. And in cancer, delayed diagnosis costs lives.

Where to Turn If You Need Backup

If you’re struggling to be heard or aren’t sure what to ask for, here are a few supports:

• Bowel Cancer Australia’s Never Too Young campaign – focused on early-onset cases and raising GP awareness
• Ask your GP for a referral to a specialist if symptoms persist beyond a few weeks
• Contact your local health consumer advocacy service if you feel your concerns are being dismissed

Final Thought

If you’ve got symptoms that won’t settle, don’t settle for an easy answer.

IBS is real, but so is the risk of misdiagnosis. Especially for younger people. Don’t let the algorithm or a rushed appointment decide your future. Push for proper tests. Speak up. Ask questions. Be annoying if you have to.

Because if it’s not IBS, you deserve to find out sooner, not later.
