Is It Really Just IBS? What Your IBS Diagnosis Isn’t Telling You

If you’ve ever left your doctor’s office with a diagnosis of Irritable Bowel Syndrome (IBS) and not much else, you’re not alone. IBS is one of the most common digestive diagnoses, affecting up to 15% of the population. But here’s the thing: IBS isn’t really a diagnosis at all. It’s more like a label for a cluster of symptoms, and for many, it ends up being what we in functional nutrition call a wastebasket diagnosis that’s typically given by doctors when they don’t know what’s really going on 

Let’s break down what IBS really is

What Is IBS?

IBS, or Irritable Bowel Syndrome, is defined by a group of symptoms that affect the digestive system. These often include:

• Bloating

• Abdominal pain or cramping

• Gas

• Diarrhea, constipation, or a mix of both

• Irregular bowel movements

  
  

While IBS can significantly impact your quality of life, it doesn’t point to a specific root cause. In fact, the conventional medical model defines IBS as a functional disorder, meaning symptoms are present, but no structural or biochemical abnormalities can be detected through standard testing, meaning it’s really hard to get a definitive conclusion to your symptoms.  

Why IBS Termed a "Wastebasket Diagnosis"

The term wastebasket diagnosis refers to the way IBS is often used: as a default explanation when all standard tests come back “normal.” You may have had blood work, an ultrasound, or even a colonoscopy, yet everything appears fine. So, you’re told, “You have IBS.”

Here’s why this is problematic:

• It lacks clarity. IBS doesn’t tell us why your symptoms are happening.

• It halts deeper investigation. Once the IBS label is applied, the search for root causes often stops.

• It usually leads to symptom management, not resolution. You may be prescribed laxatives, antispasmodics, or fiber supplements, but none of these truly heal the gut.

As a functional nutritionist who works closely with clients struggling with bloating, irregular digestion, and chronic gut issues, I see firsthand how frustrating this can be. You're seeking answers, and instead you're handed a vague label and told to follow a low FODMAP diet that doesn't actually solve anything 

The Functional Approach: Why IBS Is the Starting Point, Not the End

In functional nutrition, we view IBS not as the end of the road, but as a signpost. Your symptoms are real, and they’re trying to tell us something.

Here are some of the real root causes I often see in clients with an IBS diagnosis:

• Imbalances in the gut microbiome (dysbiosis)

• Small Intestinal Bacterial Overgrowth (SIBO)

• Food sensitivities or intolerances (like gluten or dairy)

• Chronic stress and dysregulated nervous system

• Low stomach acid or digestive enzyme insufficiency

• Parasitic or bacterial infections

• Gut-brain axis dysfunction

• Histamine intolerance or mast cell activation

When we dig deeper, we can often identify the why behind the symptoms and that’s where the healing really starts! 

Why Addressing IBS Is Essential to Gut Healing

Even if you’ve been told it’s “just IBS,” ignoring those symptoms can lead to more chronic issues down the line. Inflammation, leaky gut, nutrient deficiencies, and immune dysfunction can all stem from unresolved digestive imbalances.

Healing your gut is about so much more than reducing symptoms. It's about:

• Rebalancing your microbiome

• Restoring proper digestive function

• Reducing systemic inflammation

• Supporting your immune and nervous systems

• Rebuilding your relationship with food and your body

You Deserve Better Than a Catch-All Diagnosis

If you’ve been told you have IBS and sent on your way, know this: there is so much more we can explore. You deserve more than a label, you deserve answers a plan that helps you feel your best

In my practice, I use functional stool testing, comprehensive intake assessments, and personalized nutrition protocols to uncover the root causes behind your digestive symptoms.
