The short answer

IBS: Finding the Root Cause When Conventional Medicine Says 'It's Stress'

IBS is not a life sentence and it's not 'just stress.' Here's how integrative medicine identifies and treats what's actually driving your symptoms.

IBS Is a Symptom, Not a Diagnosis

IBS is essentially a label that says "your gut isn't working right and we don't know why." It's a diagnosis of exclusion.

Common Root Causes

  • SIBO — Up to 78% of IBS patients test positive
  • Food Sensitivities — IgG-mediated delayed reactions
  • Parasitic and Fungal Infections — often overlooked
  • Bile Acid Malabsorption — causes chronic diarrhea or constipation
  • Histamine Intolerance — excess histamine mimics IBS

Our IBS Resolution Protocol

  1. SIBO breath testing
  2. Comprehensive stool analysis
  3. Food sensitivity testing
  4. Targeted treatment — antimicrobial herbs, biofilm disruptors, motility support
  5. Gut restoration — repair lining, restore microbiome. See our leaky gut healing protocol
  6. Nervous system regulation — vagus nerve support

We don't guess. We test.

Precision or nothing.

90% of the clarity that produces outcomes comes from a precise, investigative intake — a series of questions no one has ever asked you. Testing follows the hypothesis: epigenetic DNA in DNA Precision, doctor-selected blood and urine panels in Private Concierge. Nothing gets recommended that the data can't justify.

  • We never give up

    Complex, weird, and "nothing worked" cases are the ones we take.

  • We have your back

    You are not managing this alone between appointments.

  • We always find the root cause

    We keep going upstream until the pattern explains every symptom.

  • We look at all of you

    Mind, body, exposure history, genetics, and the life you are actually living.

  • Precision or nothing

    No shotgun protocols. If we cannot justify it, you do not take it.

  • Clarity produces outcomes

    When you understand why, implementation stops being a willpower problem.
